State molar constant-volume heat capacity

Reference no:

A sample consisting of 3.0 mol of ideal gas molecules at 200K at 2.00 atm is compressed reversibly and adiabatically until the temperature reaches 250K. Given that its molar constant-volume heat capacity is 27.5J/Kmol, calculate q,w, delta U, and delta H. and final pressure and final volume. Use PV=nRT to find the initial volume in order to help solve this problem?
