One kg of water in a piston-cylinder assembly undergoes two processes in series from an initial state where p1 = 0.8 MPa, T1 = 500°C:

Process 1-2: Constant-pressure compression until the volume is half of the initial volume.

Process 2-3: Constant-volume cooling until the pressure drops to 400 kPa.

Sketch the two processes in series on a p-v and T-v diagram. Determine the work and heat transfer for both processes.
