Please show the work you've done on the problem so far, then you'll likely get suggestions for continuing.
 
This is a qualitative question not quantitative. But for some equations that do go with this are the following:
Delta(E)=Q-W --First law of Thermodynamics
 
It would be a good idea to define both: the specific heat at constant volume, and the specific heat at constant pressure.
 
Nevermind, I found the answer.
