QUESTION:

One-half kg of Refrigerant- 22 is contained in a piston-cylinder assembly, initially saturated vapor at 5 bar. The refrigerant undergoes a process for which the pressure specific volume relation is pv= constant to a final pressure of 20 bar. Kinetic and potential energy effects can be neglected. Determine the work and heat transfer for the process, each in kJ.
