Thermal Equilibrium - IB Physics

[@siyasingh7597]

Thanks for doing this series Prof Masley :) For everybody doing these sums, answer for example 2 is 657K

[@limetime1085]

Thanks, the first example just helped me solve an exam question I was stuck on.

[@kaatleemans9406]

Hello, I obtained 656.9 when doing example 2 how did you work it out?

[@1xn836]

yeah same here

[@minhajnabiorpit3959]

same, i think he got it wrong.

[@anishsujay2481]

He got it wrong cux he took the latent Heat of ice instead of water

[@pollamanxx3993]

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.

[@manreeque5887]

When he got Q for water, he rounded it up to 11400, when the actual value is 11359.6

Amazing video 👏🏽

If you think about it, the 0th law is literally just the transitive property from Geometry

[@vinanaser5604]

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

[@farrasahmadfadhlurrahman4436]

sir i got 656.9 for example 2, did i miss something? im kinda afraid that i did

[@aryaveersingh7339]

I got the same result twice with different methods, probably a calculation error in the video

[@marlondarlon1328]

yeah me too

[@Cristinee48]

How do you get 62°C in Example number 1? I solve them but the result is 0.111111

[@emekej]

There is a - before Q2 so it mean u have to put negative value in all of three brackets, (-3)(-1500)(-Tf+80)

[@aseerkhan1676]

Is contact /physical touch necessary for achieving thermal equilibrium of two system

[@zaidahmad704]

yes

[@flint9600]

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: kzbin.info/www/bejne/g3jbnKeFpNehfZY]. Is that because this video is slightly sped up/edited? Are there any meaningful differences? Thx!

[@AndyMasley]

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