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