Five Kg of water contained in a piston-cylinder assembly expands from an initial state where T1 = 400o C, P1 = 700 KPa to a final state where T2 =200o C, P2 = 300 KPa, with no significant effects of kinetic and potential energy. The accompanying provides additional data at the two states. It is claimed that the water undergoes an adiabatic process between these states, while developing work.
