A piston-cylinder assembly is fitted with stops. The assembly contains 0.1 kg of water, initially at 1 MPa and 500°C. The water undergoes two processes in series:
Process 1-2:
Constant-pressure cooling until the piston face rests against the stops, at which point the volume occupied by the water is one-half of its initial volume.
Process 2-3:With the piston face resting against the stops, the water cools to 25°C.
(a) Sketch the two processes in series on a P-v diagram.
(b) Neglecting kinetic and potential energy effects, evaluate the work and heat transfer for each process (each in kJ).
