A piston-cylinder device contains 0.8 kg of steam at 400K and 150 kPa. Steam is compressed at constant temperature until one-half of the mass condenses.

a. Sketch the process on a T- v diagram. Include the vapor dome and the constant pressure curves that pass through the initial and final states.

b. Find the final pressure.

c. Determine the initial and final volume.

d. Determine the quality at the final state.
