Problem 111HP

The piston/cylinder in Fig. P3.111. contains 0.1 kg water at 500°C, 1000 kPa. The piston has a stop at half of the original volume. The water now cools to a room temperature of 25°C.

a. Sketch the possible water states in a Pv diagram.

b. Find the final pressure and volume.

c. Find the heat transfer and work in the process.
