Apiston-cylinder apparatus contains 5 kg of refrigerant r-134a at 200 kpa and 20 °c. the piston is slowly pressed downward by a force applied to the piston. the compression process is slow such that the temperature of the system remains constant. at some point, the system becomes nearly incompressible regardless of the amount of applied force.

for the process: a) determine the initial and final volume (m3), b) determine the final pressure (kpa, minimum), c) draw the process on a p-v diagram labeling the initial and final states and including the vapor dome on the diagram.
