Honking For Honks

 Laura: Hello and welcome to another episode of Lexx Education, the comedy science podcast, where comedian me, Laura Lexx tries to learn science from her Happy New Year, brother Ron.

Ron: That's how you can tell that you're a professional because you're just right back into it.

Ron: But my blood is still seeding.

Laura: So, listeners, we are recording this intro directly after finishing last week's redo of a lesson.

Laura: He should have been so straightforward, Ron.

Laura: I don't know why he made it so difficult.

Laura: Look, last week didn't go well and that's confusing given that we'd already done it before.

Laura: And then I think it was an extra difficulty lesson, wasn't it, Ron?

Ron: It was higher tier.

Ron: Yeah.

Laura: He's drinking from his cow bell.

Laura: I got up.

Laura: How are you always so thirsty?

Laura: And why do you wait until we're recording to be talking a lot?

Ron: I'm enunciating.

Ron: I need to wet my pipes.

Laura: Don't say wet your pipes.

Laura: So, thank you very much for tuning back in again.

Laura: That is a testament to you guys, really, that you listened to last week and thought, yeah, I'll continue with this in my 2023 journey.

Ron: What I'm happy about, though, is that we might have sloughed off some dead weight.

Ron: Anyone that listened to the Christmas episodes and went, you know what, I do like this, but I'm probably not enough to binge and go back through it all.

Ron: I like that.

Ron: We've now just lost them.

Ron: They're gone.

Laura: Yeah, quitters.

Laura: They're in the rearview mirror today's episode.

Laura: Now, we haven't got any social stuff to chat because we are pre recording this a little bit ahead of time.

Ron: So that quarter can drive on the 16 December.

Laura: Yeah, because we're having some time off, like reasonable people.

Laura: Now, this episode that you're about to go into, to me, it feels like a bit like a bottle episode, which in sitcom terms, a bottle episode is an episode where you trap the characters in something like the episode of Friends, where they're all getting ready for Ross's big event but no one's getting dressed.

Laura: That's a bottle episode, a good one.

Laura: And this feels like that, to be honest.

Laura: Ron has a meltdown.

Laura: Like, Ron, I don't know what you were going through at this point, but.

Ron: Weird, I tried to count up to, like 100,000 or something, don't I?

Laura: Yeah, it goes badly for you.

Laura: But listen, we are discussing specific latent heat of fusion and all sorts of things like that.

Laura: Hey, it's better than last week in terms of scientific development, but I don't think it's going to be the one that gets us the Nobel Prize because it's very beliek in terms of understanding levels.

Laura: But listen, you enjoy it and we'll be back to say goodbye afterwards.

Ron: It's weird that this is only happening now because we talk about the specific latent heat of fusion in the Christmas episodes.

Ron: You don't remember it's fine.

Laura: Hello, Ron.

Laura: Hey, let's have a good physics.

Ron: Let's do it.

Ron: I'm pumped.

Ron: I've got a new thing where I put coffee in my protein shake, and I'm just really living.

Laura: Wow.

Laura: All right.

Laura: I've started taking iron supplements.

Ron: How heavy are you now?

Laura: So much heavier.

Laura: And my blood is more infused noise.

Laura: What we're doing today oh, God.

Ron: I mean, I know that we were going to have a good physics episode.

Laura: Don't be sad sounding.

Ron: You're not going to care about this at all.

Laura: I want to care.

Laura: No, I am.

Laura: I'm going to care real hard.

Ron: Okay, so we're going to be talking about, for a while, changes of state and specific latent heat.

Laura: All right.

Laura: I love changes of state and specific latent heat.

Ron: Yeah.

Ron: It's like when you go from Idaho to Illinois and then you have a specific latent heat.

Ron: So you know what a change of state is, don't you?

Laura: Yes, it's when the particles change from a gas to a liquid to a solid.

Ron: Exactly.

Ron: Yes.

Ron: Now, the specific latent heat of these things is that there is a certain amount of energy needed to do that change of state, which basically means that when something is like melting or going into a gas, you would be functionally heating it, but it for some time would not get hotter because it is absorbing energy to make that change.

Laura: Okay.

Ron: The internal energy of the sun is going up, but the temperature isn't changing during this process.

Laura: Okay.

Laura: Because they're converting the heat energy into.

Ron: The change of state.

Laura: Yeah.

Laura: Okay.

Ron: So it take more energy for some water that's the same thing as ice to go from minus five degrees to five degrees.

Ron: Then it would for the same water to go from five degrees to 15 degrees.

Laura: Okay.

Laura: Yeah, that makes sense.

Ron: Okay, cool.

Ron: So this is called the specific latent heat.

Ron: Okay.

Ron: The specific latent heat is the amount of energy that it would take for.

Laura: One specific latent heat.

Laura: Sounds like a man that might be in charge of your investment portfolio.

Ron: It sounds like a character from Toast of London.

Ron: Yes, toast.

Ron: The specific laden heat is coming in later.

Ron: You have that for every material.

Ron: That is the amount of energy that it takes for one kilo of that substance.

Ron: Let's take a random one.

Ron: Wood.

Ron: So if wood were to melt, for example, that would have a specific latency.

Laura: They'Ll slog in that bottle of glue.

Ron: Are you maybe so long till they hear this without a change in temperature.

Ron: So we have a formula for this.

Laura: I'll put in the sound effect of the little girl saying woohoo, because I'm not woohoo.

Laura: That's a little girl woho.

Laura: Yeah.

Laura: What do you think?

Ron: I thought you were talking about the sarcastic.

Laura: No, I think that that's you watching a man who's already dead get tortured whilst someone else does the sound effect.

Ron: Right.

Ron: So the formula is capital E.

Ron: Good to be capital E.

Ron: Laura Echo, someone.

Laura: On TikTok was explaining to me hello, Alex.

Laura: About why c means the speed of light.

Laura: And it's because the C stands for constant, and constant just happens to be the speed of light.

Ron: Yeah.

Ron: That makes sense.

Laura: Yeah.

Ron: Makes sense for both of us to.

Laura: I've memorised that sentence.

Laura: I don't fully understand what it means, but I can say that sentence.

Ron: I think it's because the speed of light is constant.

Laura: It's a constant in the universe.

Laura: The speed of light.

Ron: Yeah.

Laura: It's always the same.

Ron: Yeah.

Ron: Anywho, so capital E, fifth letter of the alphabet, echo.

Laura: It's like an upward line.

Ron: London or green?

Ron: Washington DC.

Laura: Lines coming off the side.

Ron: Yeah.

Ron: Equals that's just like two lines next to each other.

Ron: Looks like a Chinese number two.

Laura: Didn't know that.

Ron: Then we go for a small M.

Ron: We know this guy.

Ron: We've sat next to him on the bus before.

Ron: That's masked.

Ron: We've done all of the possible jokes.

Ron: We have scraped that barrel dry.

Laura: A little M.

Laura: Sort of looks like a bum sticking up.

Ron: Does little bum with a tail or maybe a winkie.

Laura: Why don't give it a tail?

Laura: A little M.

Laura: Oh, I just do it like a little soft bum and.

Ron: Then a capital L.

Ron: That is the specific latent heat.

Laura: Energy equals mass multiplied by the specific latent heat.

Ron: Yup.

Laura: I've got a couple of properties in West London.

Ron: So that tells us that mass and the specific latent heat, they have just a proportional relationship.

Laura: Yeah.

Ron: If you double the mass, you double the amount of energy you need.

Ron: You double the latent heat, you double the amount of energy you need.

Ron: Can you laura a smart woman that went through higher education.

Ron: Higher tell me what the unit of specific latent heat is.

Laura: Jules, don't just say things.

Ron: Apply months of context.

Laura: I f****** did.

Laura: You think Jules would have been the first word out of my mouth three months ago?

Ron: Well, you and I know, being a house of learned doctors, that the unit for energy is dual, so potentially no, it's not.

Laura: Jewels again, that's why I thought it would be.

Laura: Because you said it was latent energy.

Ron: No, I said it was specific latent heat.

Laura: Heat kelvin.

Ron: No, that's a heat and temperature at very different things.

Laura: Are they?

Ron: Yeah.

Laura: That sounds like a lie.

Laura: Is that a word?

Ron: I know it's a unit.

Laura: Is it a unit I know?

Ron: No, I'm asking you to work it out.

Laura: How can I work it out?

Ron: Because it's not just like brimblies.

Ron: It's something that you can work out from the information I've already given you.

Laura: Have I got to rearrange this equation?

Ron: Yeah.

Ron: So what's the unit for?

Ron: Mass.

Laura: Mass kilogrammes.

Ron: Yeah.

Ron: Okay.

Ron: As discussed, the unit for energy is joules.

Laura: So L equals let me think about this.

Ron: E equals should we start drinking out of a cup when we yeah.

Laura: You are so weird.

Laura: E equals M times l.

Laura: That's what I can't do.

Laura: That's a revelation, and I'm not I'm thinking it through.

Laura: E equals M times L.

Laura: So to get L on its own, you've got to divide M out of it again.

Laura: So I think there's two options here.

Laura: It's either going to be L equals M over E or E over M.

Laura: Is it one of those, Ron?

Ron: Yeah, quite apparent.

Laura: Which so let me think.

Ron: When you do math so the heat thing, you need to you got loading to both sides.

Ron: Stop just trying to suss this out with wily Earthy knowledge.

Laura: I've got to do the same to both sides.

Laura: So it's e over.

Laura: M then?

Ron: Yes.

Ron: You got to divide both sides.

Laura: Both sides by M.

Laura: Yes.

Laura: Okay.

Ron: So what does that make the unit for?

Ron: L?

Laura: E over m.

Laura: No, that's how you.

Ron: Would calculate L.

Ron: You'd divide the energy by the mass.

Laura: So Joules killer jewels don't just say.

Ron: Things I don't think ever in science is the answer of Portmanteau.

Laura: Jules kilogramme.

Ron: Because it's joules divided by kilogrammes.

Ron: So joules per kilogramme, which makes sense because it's the amount of energy needed per kilogramme.

Laura: Yes.

Laura: All right.

Ron: Yeah.

Ron: Okay.

Ron: So just a couple of terminology things.

Ron: So in general, this is called specific latent heat, but then we also have the specific latent heat of fusion, so that is solid to liquid.

Ron: And we have the specific latent heat of vaporisation, which is the change from liquid to a gas.

Laura: Okay.

Ron: Is that what fusion means, fusing things together?

Laura: It always sounds more like tropical science than just freezing is fusion.

Ron: What's tropical science, babe?

Laura: Like cooler signs than just freezing.

Laura: Something like the kind of science you.

Ron: Might do to make a coconut radio.

Laura: Nucleus.

Laura: Space exploration feels more intense science than just freezing ice cubes.

Ron: Well, if you've got the episode title sorted.

Ron: Right, okay.

Ron: So we're going to do some calculations.

Ron: Okay.

Laura: Okay.

Ron: So firstly, we're going to work out how much.

Ron: We're going to do a calculation about condensing some steam into water.

Ron: Okay?

Laura: Okay.

Ron: Write this down.

Ron: 5.65 times ten to the power of six joules of heat energy is removed from wow.

Laura: Because could you go a bit slower if you're going to go drag it down five now on .6 yeah.

Ron: Times ten to the power of six times ten.

Laura: And that's the little six up the top yes.

Ron: Of heat energy is removed from a mass of steam.

Laura: Heat energy.

Laura: I just write out the words heat energy.

Laura: Or is there a symbol for that?

Ron: Well, you could call it E, because in this it would be e heat energy removed from a massive steam at 100 degrees Celsius to produce war.

Laura: This is a sentence.

Ron: You don't have to write all of this down.

Laura: Well, f****** how do I know why I'm supposed to be right down?

Ron: Listen to it and write down the bits you need.

Laura: I don't know what bits I need.

Ron: Is removed from a massive steam at 100 degrees Celsius to produce water at 100 degrees Celsius.

Laura: Now, which bits of that.

Laura: Do you want me to write?

Laura: Bearing in mind I've already put 5.6 times ten, six heat energy brackets E removed.

Ron: Sorry, say that again.

Laura: 5.6 times ten.

Laura: Six heat energy e removed.

Ron: From some steam.

Laura: From some steam.

Ron: The steam is at 100 degrees Celsius.

Laura: Okay.

Ron: It makes some water that is also at 100 degrees Celsius.

Laura: Okay.

Ron: So what does that tell you?

Ron: Instantly?

Laura: Somebody's lying.

Ron: Why?

Laura: You can't no, don't have to be lying.

Laura: You can be steam or water at 100 degrees.

Laura: You get to choose.

Ron: Yeah, because it's kind of the concept that we discussed in the first part of the episode about the specific latent heat.

Ron: You remember that?

Ron: Remember ten minutes ago?

Laura: Yeah about it.

Ron: So remember when we were talking about that and I said that you can put a lot of energy in, but it wouldn't necessarily raise or drop the temperature because we've removed a bunch of energy from the steam, but it stayed the same temperature, which means that that.

Laura: Energy is changing its mass matter.

Ron: Yeah, exactly.

Ron: But it's not changing the temperature.

Ron: So we can use this to work out with the specific latent heat.

Ron: Yeah.

Ron: Okay, so write this down.

Ron: The specific latent heat of vaporisation for water is 22.64 hang on.

Laura: That accounts for vaporisation of water is.

Ron: 22.64 times ten to the power of five joules per kilogramme.

Ron: And now the question is how much?

Ron: How much water have we produced?

Laura: F*** knows.

Laura: There's no way of knowing.

Laura: Can you just know that from those?

Ron: Laura, I think this formula could scarcely be more simple.

Ron: It's literally just two numbers multiplied together.

Ron: Yet in this case, you need to do a modicum of rearranging.

Ron: But to be honest, yeah, this is well easy.

Laura: Wait.

Laura: Oh, my God.

Laura: You did your lingo for, like, three months and you think to yourself, I'm practically fluent now.

Laura: And then you listen to a podcast in that language or something and you go, oh, what's the point?

Laura: That is how I feel right now.

Laura: So what's happening?

Ron: We've got the amount of energy I.

Laura: Run, and can we just go back to the beginning now?

Laura: I've written all that out.

Ron: Okay, so 5.65 times ten to the power of six joules of heat energy is removed from some steam.

Laura: How do you even do that?

Laura: Let's stick an ice pack in.

Ron: Yeah.

Ron: It dissipates.

Ron: You know how things cool down?

Ron: Things don't just get hotter.

Laura: Yeah.

Ron: Like all the time.

Ron: So, yeah, that amount of heat energy is getting removed from some steam.

Laura: Yeah.

Ron: The temperature is not dropping.

Ron: No.

Ron: So we know that this is all to do with the latent heat of vaporisation.

Ron: Now, I know what you're thinking.

Ron: This water is not getting vaporised.

Ron: Wrong.

Ron: This water is getting condensed.

Laura: It's fusioned.

Ron: It's getting fusioned.

Ron: But vaporisation and condensation are the same process, but just in different directions.

Ron: So they take the exact same amount of energy, because in one, you're just putting the energy in and in the other you're just taking the energy out.

Laura: Yeah.

Ron: So we have E, we have L.

Ron: I gave that to you as well.

Ron: 22.6 times ten to the power of five.

Laura: Yeah.

Ron: Okay.

Ron: We're trying to work out how much water.

Ron: Now, we're going to do that as a mass, and handily mass is one of the things in the formula that we've got.

Ron: So work it out.

Ron: Get M on its own first.

Ron: How do we do that?

Laura: Hang on a minute.

Ron: No, do that.

Laura: F*** you.

Laura: And listen.

Laura: So, with the formula E equals ML.

Laura: Now, that formula looks like 5.65 times ten to the power six equals M times 22.64 times ten to the power five.

Ron: Yeah?

Laura: Yeah.

Laura: Okay, so to get M on its own, it would be M equals 5.65 times ten to the power six, divided by 22.64 times ten to the power five.

Ron: Yes.

Laura: Do you need me to do that or shall we just skip, like, a load of me hammering a calculator and you just tell me?

Ron: No, you can work that out.

Laura: I don't.

Ron: You understand standard form, right?

Laura: No.

Laura: What does standard form mean?

Ron: Like, all of this ten to the power of nonsense.

Laura: I know how to do ten to the power of it's.

Laura: Like, ten times ten times ten, five.

Ron: Times yeah, but, you know, sort of why that's used.

Ron: It's just a way of writing very large numbers quickly.

Ron: So the number above the ten that the ten has been done to is the number of zeros, basically, that you could whack on the end if you wanted to.

Ron: It's called standard form.

Ron: It's just a way of displaying large numbers.

Ron: I do remember when we did Moles and then it was like six to the times ten to the power of 23.

Laura: Yeah.

Ron: And then it was six with 23 zeros.

Ron: See how that's a big number?

Ron: That would be a ball lake to type out every time.

Laura: We hate this so much.

Laura: Oh, God.

Laura: When's it biology again?

Ron: Next week.

Ron: But we have to do cancer.

Laura: What?

Laura: Does biology have to betray us?

Ron: Yeah.

Ron: We're in the woods in every single subject at the moment.

Laura: F****** out.

Laura: I don't really know what you're saying.

Laura: I'm not listening.

Ron: Jesus Christ.

Ron: Divide the numbers, Laura.

Laura: Well, why were you telling me about something else, then?

Laura: It felt like that must have been important.

Ron: I just thought you might want to understand what you're doing.

Ron: But you know what?

Ron: After 25 episodes, my bad.

Ron: Divide the numbers, let's move on.

Laura: I've got to do some multiplying before I can do some dividing.

Laura: Is that what you were saying?

Laura: How to do this without doing all of it?

Ron: I was just trying to explain to you what standard form was because I thought it might be more I thought it might be less intimidating if you understood why these, errant, tens were everywhere.

Ron: What you could do is just cancel out the tens on either side.

Laura: Oh, just have ten.

Laura: One at the bottom.

Ron: Well, so it's ten to the power of five at the bottom.

Ron: So if you cancel that out with the ten to the power of six.

Laura: At the top, five at the top.

Ron: No, because it was E divided by M.

Ron: E divided by L, wasn't it?

Laura: E divided by l.

Laura: Yeah.

Laura: If I've been doing this the wrong way round, does the wrong other one go on the top?

Ron: If you've got the other one on the top, then yeah.

Laura: F****** h***.

Laura: Wait, when you do a divided by two divided by three, the three goes on the top?

Laura: No, two thirds.

Ron: Yeah.

Ron: Two over three.

Laura: Two.

Laura: Wait, but two thirds is two times three.

Laura: Oh, my God.

Laura: The world's collapsing in on me and I can't remember making this.

Ron: Two thirds isn't two times three, this is two times three.

Laura: Bits.

Ron: It's two times a third.

Ron: Yeah.

Ron: Jesus Christ.

Laura: Well, I just feel despondent the numbers.

Ron: Laura.

Ron: Right, let me make this a lot easier for you.

Laura: Yes, please.

Ron: What we can do first is we can just divide ten times ten to the power of six by ten to the power of five, and the answer to that is just ten.

Ron: So then we can just multiply 5.65 by ten and then we can divide 56.5 by 22.64, and then we get our answer.

Laura: But which one goes on the top?

Ron: The one that you're dividing.

Laura: That feels wrong somehow.

Ron: Sorry, but it's not.

Laura: Lord, this feels like, you know when you say a word too much and so it just loses all meaning to you.

Ron: Don't pretend you've been doing lots of division in your spare time.

Ron: It's lost all meaning to you.

Ron: Yeah, I was just dividing some numbers the other day and yeah, also, I did so many divides then.

Laura: No, I can't remember which way round they go.

Laura: So 2.5, essentially.

Ron: 2.5 kilogrammes.

Laura: Kilogrammes, yeah.

Ron: Because mass is measured in kilogrammes.

Laura: So what have we done?

Ron: We've worked out how much water there was, essentially.

Laura: Okay.

Ron: You need to stop expecting the f****** cure to diabetes to be at the end of one of these questions, because it's always just going to be a number.

Laura: I just get I have to zoom in so far to do the middle bit that then it's like my eyes can't readjust to what we were doing overall.

Ron: There wasn't a middle bit, there was all that dividing.

Laura: That was the only bit.

Ron: It was a one step formula.

Laura: First of all, I had to set the formula up into numbers out of letters.

Laura: It does count.

Laura: Yes.

Laura: Because otherwise it's just L equals em.

Laura: And I turned that into M equals 22.64 over 10.5.

Ron: That's just writing things down.

Laura: No, it's translating.

Ron: We're going to do another one.

Laura: Same thing.

Ron: No, completely different, actually.

Laura: F****** h***.

Ron: This time we're going to work out how much energy we need to change.

Ron: Zero point 65 kilogrammes of ice.

Laura: I'm worried about our relationship because I'm worried I'm just going to start phasing you out.

Ron: Oh.

Ron: I'm just putting money away so that I can put you in a home at some point.

Laura: Just going to start associating your voice.

Ron: With can you stop fiddling, please?

Laura: Yeah.

Laura: My little national treasures.

Laura: Travel cup.

Ron: I had one of those.

Laura: Which one had where's?

Ron: It on the logo, rubbed off of it.

Ron: So now it's just a cup.

Laura: Did you put it in the dishwasher?

Ron: I think so.

Ron: Right.

Ron: So we're going to calculate the amount of energy that it takes to melt zero point 65 kilogrammes of ice, basically.

Laura: Okay.

Laura: Have I got everything I need to do that?

Ron: No.

Ron: The piece of information that you're missing is that the specific latent heat of fusion for water, that is the one that happens at this end of the temperature scale is 3.34 times ten to the power of five.

Laura: 3.34 times ten to the power of five.

Laura: That's e in this equation.

Ron: No, that's L.

Ron: We're trying to work out E.

Laura: F****** L.

Laura: And how much mass did you say I had?

Ron: 0.65 kilogrammes.

Laura: So to get E on its own, I need to multiply it by zero 65.

Ron: Look at the formula again.

Laura: L equals E over M.

Laura: Look at.

Ron: The formula when I first gave it to you.

Laura: Equals ML.

Ron: Yeah, that's the formula I gave you the formula in.

Laura: Where did I get the other one from?

Ron: Well, we were trying to calculate L when we were working out the unit, so we did that.

Laura: Okay, so we don't have to do a flip reverse on this one?

Ron: No, because we've just got it.

Laura: So it's just zero 65 times 3.34 times ten to the power five.

Laura: Yeah, it's ten to the power 5100,010.

Ron: Times ten is 110, times ten to the two is a 1010, times ten to the three is 10,010, times ten to the four is 100,000.

Laura: That's a million.

Ron: Ten on its own is 1010, times ten is 110, times ten to the two is ten times ten to the four is 10,000.

Ron: But ten times ten no, I did 10,000 twice.

Laura: It's a new feature called Ron's Breakdown.

Ron: Believe it or not, I just made up that song.

Laura: Yeah.

Laura: Did it help you?

Ron: It confused me.

Laura: Yeah, you and me both, buddy.

Ron: So have you multiplied these two numbers together?

Laura: Well, I think I have.

Laura: I can do a scientific calculator.

Laura: I've managed to get my calculator to just display the words, not a number.

Laura: That's fun.

Laura: Ron, how do I do ten to about five?

Ron: Doesn't it let you just do that in your calculator?

Laura: I don't know what any of these buttons do.

Ron: There's usually, like, a button that you can press.

Ron: There's, like, ten times ten, and then you just put a number after it and then you do it.

Ron: Or didn't we just work out that it was a million?

Laura: I don't know.

Laura: Did we?

Ron: Let's have another try ten on it.

Ron: But ten to the power of one is 110 times ten to the power of two is 1000, and to the power of three is 10,009.

Laura: Zeros is?

Ron: A million is 100,005 is 1 million.

Ron: Yes, it's a million.

Laura: It's a million.

Laura: Okay, if it's a million, then you're doing a million times 3.34 times zero point 65.

Laura: So that makes e 2,171,000.

Laura: And what was the sum that you did?

Laura: I did 3.34 times a million for L multiplied by zero point 65 for M equals 2,171,000.

Ron: You'Re a power of ten out according to BBC byte size.

Laura: Why is that, then?

Ron: I don't know, I thought we were solid, but can you do the song, see if it works for you?

Laura: Well, I just googled instead of a song, I just Googled ten to the power ten and it comes up with a million.

Ron: Wait, but ten times ten to the power of what?

Laura: No, it doesn't.

Laura: It's 100 million.

Laura: No, it's 10 million.

Ron: No.

Laura: Oh, my God.

Laura: Ten, two, three.

Laura: Yeah, it's 10 million, Ron.

Ron: No, it's not.

Laura: Isn't it?

Ron: No.

Ron: Ten squared.

Laura: 100.

Ron: So then ten to the three is a 1010, to the four is 10,010 to the five is 100,000.

Ron: Yeah, it's 100,000.

Ron: The song really f***** me up.

Laura: Wait, why was I doing ten to the power ten?

Laura: It's ten to the power five.

Laura: Googled that.

Laura: Yeah, okay.

Laura: Oh, my God.

Laura: 334 times zero point 65.

Laura: So E equals 217,100.

Laura: Joules.

Ron: Yes.

Ron: And that's what we're going to do today.

Laura: Okay.

Laura: And now, as I stare at the page, and this vaguely makes sense, it's like someone just pours a glass of water over it, a jingle will play and we'll be back next week.

Laura: And I'll be looking at this and going, what the h***?

Laura: Ronnie.

Laura: Ronnie Holmes.

Ron: Ronnie.

Ron: Ronnie Holmes.

Laura: Nicer Bratto.

Ron: Thank you.

Ron: I'm a singer.

Laura: Oh, my goodness.

Laura: People are angry outside your house today.

Ron: That Friday honk vibes running.

Ron: Honks.

Laura: Honking for honks, honking for honks.

Laura: There's a merch idea if ever we had one.

Laura: Honk, honk air.

Laura: Hons that say honking for honks.

Laura: That will be for when you run as local councillor.

Laura: Ow.

Laura: I punched the microphone.

Laura: Sorry about that noise.

Ron: Right, time for physics.

Laura: Was it physics?

Ron: Yeah.

Laura: Oh, no, it was more sums those f******.

Ron: Moles, wasn't it?

Ron: No, it was physics.

Laura: Isn't that moles?

Ron: No, moles.

Laura: Oh, no.

Laura: It was that Tory MP.

Laura: Just for latent heat.

Laura: I remember now.

Ron: Yes, exactly.

Ron: Well, yeah.

Ron: So what is specific latent heat, Laura?

Ron: That's the first question.

Laura: Latent specific latent heat is when you can put more energy into a thing, but the temperature doesn't rise because it's changing matter state.

Ron: Yeah, that's it.

Laura: I wish you hadn't been pinching your nose all the way through that.

Laura: No, I was just really tin for garbage.

Ron: No, but you were kind of speaking like this, so I just needed to really focus to pull all of the words together.

Ron: But no, yeah, it was.

Ron: Right.

Laura: It's because I haven't actually written down I've written down specific latent heat and then I've written about heating things, but I hadn't actually drawn an arrow between the two to say whether that was what that was.

Ron: Yeah, but again, there shouldn't be an exercise in just you writing a small s***** book about these s***** science.

Ron: Is this supposed to be about you learning?

Ron: It so good that you didn't write it down.

Laura: I don't know what the difference is between learning it in my book and learning it.

Laura: I'm not going to ever have all of this just in my head run.

Laura: I think if that's your aim, you.

Ron: Are going to be teaching because like I say, at the moment, you're just making a crap book.

Laura: Yeah, but that's unreasonable.

Laura: It's unreasonable to assume that there's going to be a point where I just know all this.

Ron: That's the idea.

Laura: I know it's the idea, but it's unreasonable.

Laura: It's not going to happen because I've already learned all of this and sat an exam on it and now it makes me the angriest I've ever been in my life.

Laura: So I think understanding my small s***** book is about as good as my.

Ron: Learning is going to become fair of that.

Laura: F*** if you do that, is that an extra point?

Laura: No, I wish.

Ron: You're doing a debate on your ship.

Ron: Okay, so second question.

Laura: Calculate what's happening.

Ron: I'm sitting on my foot.

Ron: Calculate the thermal energy needed to freeze 500 grammes of water at zero degrees.

Laura: Oh my God.

Laura: OK.

Ron: The specific latent heat of fusion for water is 334 times a thousand.

Laura: Immediately I feel furious, I feel angry, my eyelids feel sweaty.

Laura: I'm mad at you and I think insulting you personally would alleviate the agony of this.

Ron: Can I loop you in on something then?

Laura: Yeah.

Ron: So what episode is this?

Ron: Is like episode 30 or something?

Laura: 28.

Ron: 28?

Ron: Yeah.

Ron: So up until last episode, basically, I've just been making all of these sums and stuff up.

Ron: I've been working them out and doing the calculations myself and stuff.

Ron: Then last week I was just like, I could just get these from the internet, so I'm just on BBC buysize right now.

Laura: So you're not learning anything either, you're just repeating it off a small s***** website.

Laura: At least I wrote my own book.

Ron: I know this stuff.

Ron: No, it's not that I'm not doing the research, I'm still doing that.

Ron: It's the sums and stuff like and like the balancing of equations and things like this before.

Ron: I've been making all of that up and working it all out myself.

Ron: I don't need to do that.

Laura: No, no.

Laura: Smart one.

Laura: What was the question?

Ron: 500 grammes of water?

Laura: Yeah.

Laura: What am I doing to it?

Ron: How much energy does it take to melt?

Laura: Melt water?

Ron: The specific latent is melt.

Laura: Melting.

Laura: You can't melt water?

Ron: Yeah.

Ron: Frozen water.

Laura: Oh, yeah.

Ron: The specific latent heat of fusion is.

Ron: 334 kilojoules per kilogramme.

Laura: What's happening outside Honk's house, Ronnie?

Laura: Honks honkandi.

Laura: Honker tea.

Laura: Right, energy equals the mass, which 500 grammes of water.

Laura: I think the IRS of water is kilogrammes.

Laura: So let's say 0.5 of water times by.

Ron: It'S 334 kilojoules per kilogramme.

Laura: I don't know what that means.

Ron: Well, you know the difference between a gramme and a kilogramme?

Laura: Yeah.

Ron: The same as the difference between a joule and a kilojoule.

Ron: So same as the difference between a metre and a kilometre.

Ron: Same as the difference between a metre and a kilometre.

Laura: Oh, patch it in.

Laura: L equals joules per kilogramme.

Laura: So kilojoule is bigger than a joule.

Laura: So I got to divide that by 1000.

Ron: No, because the kilojoule is bigger.

Laura: So that is 334,000 times one.

Ron: Where did you get that from?

Laura: Because an L, which is the latent heat, which I need to finish my E equals ML equation, and L is joules per kilogramme.

Laura: That bit was right, but the M 334,000.

Ron: But where did you get the one from?

Laura: Because you said the latent specific fusion of water was 334 kilojoules times a thousand kilogrammes.

Ron: Times a thousand kilogrammes.

Ron: Yeah, I didn't say that.

Laura: What did you say?

Ron: I didn't particularly comment.

Laura: You definitely said something about I've written down 334 times 1000.

Ron: Yeah, that's how you convert between kilojoules and joules.

Laura: So did that have nothing to do with kilogrammes?

Ron: No, you worked out the mass, you quite astutely said 500 grammes and then you were like, kilogrammes is the IRS, which I assume you mean the Si unit.

Laura: Yeah.

Laura: So E equals 0.5 times just 334,000 kwh.

Laura: Yeah, I can do that.

Laura: Where's my calculator?

Laura: I don't know why you confused it by talking about kilogrammes.

Laura: Three.

Laura: Three 4000 divided by two.

Laura: So e equals 167,000.

Ron: Yep.

Ron: That's a mark.

Laura: 167,000 watts.

Ron: Work it out.

Ron: What's the unit of mass?

Laura: Kilogrammes.

Ron: What's the unit of the specific latent heat of fusion?

Laura: Joules.

Ron: No.

Laura: Kilojoules?

Ron: No.

Laura: Degrees?

Ron: No.

Laura: What is it?

Laura: Specific latent heat.

Laura: Fusion.

Ron: Specific latent heat?

Ron: Yeah.

Ron: What's the unit of that?

Laura: Oh, is this one of the E over M?

Ron: Yeah.

Laura: So it's joules per kilogramme.

Ron: Yeah.

Ron: So what's the unit for E?

Laura: Joules per kilogramme.

Ron: No, that's the unit.

Laura: Okay.

Ron: You just used it to work that out.

Ron: You're like E over M.

Ron: That must be jewels per kilogramme.

Ron: We're trying to figure out what the unit for E is right now.

Ron: This is like that bit in one of those Bugs Bunny cartoons where he pops out the hole on the other side and hands down a fudder shotgun.

Ron: And you used it somewhere else.

Laura: E equals its.

Laura: Wait, what's L?

Ron: Joules per kilogramme.

Ron: Remember?

Laura: Because E.

Ron: You said that E over M, e means Jules per kilogramme.

Ron: So what's E?

Ron: What's the unit for e?

Laura: Jewels.

Laura: Yeah, I thought I'd already guessed that.

Laura: I guessed that for L, though.

Ron: Yeah, and then you used it in the equation to work out L.

Laura: So E equals 167,000 joules per kilogramme.

Ron: No, joules.

Ron: That's energy.

Laura: It's just joules.

Ron: Joules is the unit of energy, no matter what type of energy.

Laura: First thing, I guess.

Ron: Well, you were guessing for L then.

Laura: Okay, never mind, I got the point.

Ron: Yeah.

Ron: Word of the day thing on my laptop and it just flashed up and said, disgruntled.

Ron: Give me a definition.

Laura: Any more questions?

Ron: No.

Ron: Honestly, I couldn't give a s*** with this quiz.

Laura: Your energy is slipping.

Ron: That's not true.

Ron: It's just I could not force myself to care about this, because also, any question I ask you is going to be like, yeah, there's this much of a liquid that's either condensing or evaporating.

Ron: Work it out.

Ron: And I cannot stress enough that formula is two numbers f****** multiplied together.

Ron: I don't have time to teach a pilchard like you how to do that anymore.

Laura: Pilched.

Laura: So there we go.

Laura: Ron, specific latent heat.

Laura: I think you'll agree that listening back to that, you are very mean.

Ron: Yeah, you deserve this.

Laura: Anyway, if you've got the answers to whatever ten to the Power Five should be, or perhaps you've got a little song that might help us understand it, let us know, get in touch on social media, and we'd be happy to hear from you.

Laura: Thanks for listening, beautiful listeners.

Laura: Don't forget.

Laura: You can follow us on Twitter, Facebook, Instagram, TikTok You can email us.

Laura: Lexeducation@gmail.com.

Laura: Lil ronnie Honks loves an email.

Ron: Long form.

Laura: He loves an email.

Laura: He just loves friends.

Laura: And we will be backing next week with beautiful, sexy biology.

Laura: Yeah, cluster Smith, where everybody's happy?

Laura: Sorry, Ron.

Laura: I talked over your cluster.

Laura: Smith.

Laura: You can do it.

Ron: Cluster Smith on your bike.
