A piston-cylinder contains gas initially at 3500 kPaa with a volume of 0.03 m3. The gas is compressed during a process where pV1.25 = C to a pressure of 8500 kPaa. The heat transfer from the gas is 2.5 kJ. Determine the (a) Work and (b) change in internal energy, neglecting changes in kinetic and potential energies. (Ans: -90 kJ, 87.5 kJ)
