He got it wrong 100% because I’m doing the calculation correctly and I don’t know why I don’t get his same answer. He should make a change because this things kill me.
Okay so if we are only considering the magnitude Q1=Q2 then delta T will have to be Thot-Tcold BUT if we considered that -Q1=Q2 then delta T will be Tfinal-Tinitial
Thank you so much! Your videos are incredibly helpful 🙌 But, I notice that some of your Topic 3 Thermal Physics videos like this one have a slightly longer unlisted version [example: ua-cam.com/video/MGxktOornG4/v-deo.html]. Is that because this video is slightly sped up/edited? Are there any meaningful differences? Thx!
Thanks for doing this series Prof Masley :)
For everybody doing these sums, answer for example 2 is 657K
Hello, I obtained 656.9 when doing example 2 how did you work it out?
yeah same here
same, i think he got it wrong.
He got it wrong cux he took the latent Heat of ice instead of water

When he got Q for water, he rounded it up to 11400, when the actual value is 11359.6
Thanks, the first example just helped me solve an exam question I was stuck on.
Amazing video 👏🏽
sir i got 656.9 for example 2, did i miss something? im kinda afraid that i did
I got the same result twice with different methods, probably a calculation error in the video
yeah me too
If you think about it, the 0th law is literally just the transitive property from Geometry
Okay so if we are only considering the magnitude Q1=Q2 then delta T will have to be Thot-Tcold
BUT if we considered that -Q1=Q2 then delta T will be Tfinal-Tinitial
How do you get 62°C in Example number 1? I solve them but the result is 0.111111
There is a - before Q2 so it mean u have to put negative value in all of three brackets,
(-3)(-1500)(-Tf+80)
Is contact /physical touch necessary for achieving thermal equilibrium of two system
yes

Yeah I went back and updated some of these to sound more natural, no other difference besides the speed of the audio!
