Hello All, I am interpreting a diagram from the following question.
(I didnt have a chance to take thermo and I learned it by myself so I might have some problems)
http://www.physicsgrad.com/pgre/9677-15
I understand that I can just do ΔW and I get the right answer,
but upon doing it with the specific heats, I am a little confused.
The isobaric process (B->C) specifically:
I looked at this solution:
http://grephysics.net/ans/9677/15
Why, in the calculation of U, is there C_v present?
I thought the pressure was constant, and the volume changes,
then why is U = C_v(ΔT)??
Any advise appreciated.
