A closed, rigid tank contains Refrigerant 134a initially at 100°C. The refrigerant is cooled until it becomes saturated vapor at 20°C. Kinetic and potential energy effects can be ignored. For the refrigerant:

a) Show the process on a T-v diagram

b) Determine the initial and final pressures, each in bar

c) Determine the heat transfer, in kJ/kg.
