5 kg steam expands in a piston-cylinder device from a pressure of 5 bar and 700°C (h = 3925.97 kJ/kg, s = 8.5892 kJ/kg.K, u = 3477.52 kJ/kg) to a pressure and temperature of 3 bar and 600°C h = 3703.20 kJ/kg s = 8.5892 kJ/kg.K, u = 3300.79 kJ/kg ). If the process is reversible and adiabatic , the total work (kJ) for the process will be:
