A sample consisting of a 2.5 mol of a perfect gas at 220 K and 202.6 kPa is compressed reversibly and adiabatically unitil the temperature reaches 225 K. Given that it's molar constant volume heat capacity is 27.6 JK^-1 mol^-1. calculate (a) q, (b) w, (c) delta U, (d) delta H and final pressure and volume.
