1. Prove that the slope of an isochoric process in a T-S diagram is T/Cv where T is the temperature and Cv is the heat capacity at constant volume
2. dQ = T * dS (I understand this)
dQ = Cv * dT for isochoric processes (I don't understand this)
3. Since the two equations share dQ I set them equal to each other:
Cv * dT = T * dS
Then I just rewrote the equation as:
T/Cv = dT/dS
And dT/dS describes the slope of the line which is T/Cv
My main problem is that I don't understand why dQ = Cv*dT. The book just gave it to us, but I'm thinking that I need to be able to derive it or the problem is just too easy.
