1. The problem statement, all variables and given/known data The energy of a gas is given by: E = 3/2*NkT-aN2/V, where E, N, k, and a are held constant (or are just constants). Volume V1 with temperature T1 expands adiabatically into V2. Determine T2. 2. Relevant equations All in part 1. 3. The attempt at a solution I'm not exactly sure how to start on this problem. I'm not asking for an answer, but some tips on how to proceed would be appreciated.
