Physics 32.5 Statistical Thermodynamics (27 of 39) Entropy Change for Moving N Molecules

To donate:

We will calculate what the change of entropy will be when we take a number of molecules in a box and reduce the box to a smaller section with the same number of molecules.

Next video in this series can be seen at:

If in free expansion the volume of the right part is twice that of the left part, calculate the entropy change of the system with both thermodynamic and statistical approaches. What's the

Now i can say that i am begaining to understand Statistical Thermodynamics, wonderful lecture, I want to clarify one thing is that delta U = 0 that means Q=W and W=pdV form ideal gas law we get Q= nrtlnV2/V1, Meaning this is Assumed to be right when we have low pressure and high temperature.
Again thank you very much for a wonderful lecture.

I just love the fact that President of Russia is also interested in science and explains beautifully!! 😜😊

Thank you very much for another great lecture! I just didn't understand where the equation for the probability came from, is it derived from the microstate distribution equations?

Thanks a lot sir! nice teaching style!

One of the best things I've learnt on the years of university was the english language. Without that, I wouldn't be watching your video! 😃
Thank you for your videos Michel! Regards from Argentina!
