Very good video, but at 47:37 he says "room temperature liquid helium." I'd love to see the phase diagram that shows room temperature liquid helium.

I'm starting to love physics through these videos.

Excellent, It took me a while before finding this knowledge mine, great job Doc.

@jiin5993 It took a bit of puzzling through but you are correct. The ' v ' in (dU/dT)v should have reminded him that it was at constant volume. Luckily the lecture notes, page 3, Lec 3) have it correct.

@marqtheballer1013 : d is "infinitesimal change". It comes from calculus, which you should take. Until then, you can pretty much think of it as the same thing as "delta": it just means change, except to find it you don't use 'final - initial', but "(x+h) - x", where x is a variable in a function and h is any number so small it's practically zero.

what does the letter d stand for?
IMPORTANT! This guy is awesome and i love these lectures BUT @ 14:30 he makes a mistake by saying that Cv is equal to the internal energy change with the volume at constant T ((dU/dV)t). Cv is equal to the relation next to that: (dU/dT)v. This of course makes sense because heat capacity tells you how much energy must go in or out of the system (dU) to raise or lower the temperature (dT).
Have fun studying!
