PV=nRT
PV=NkT
C=(dU/dT)
The Attempt at a Solution
I'm just frustrated with this review problem and think I may be over thinking it but I am not given an initial pressure or volume and so I am not sure where to even start with this problem. Could someone please give me a push in the right direction.
