Cv is given by__________________?
Correct answer: A. (∂E/∂T)V
- A. (∂E/∂T)V
- B. (∂E/∂V)T
- C. (∂E/∂P)V
- D. (∂V/∂T)P
Explanation
By definition, heat capacity at constant volume is the change in internal energy with temperature while volume is fixed: Cv = (∂E/∂T)V. The other derivatives do not represent constant-volume heat capacity.

The more specific you are, the faster it gets fixed. A source beats an opinion.
