Refrigerant 134a in a piston cylinder assembly, from 180 psi and 140 F to 30 psi. The mass of refrigerant is 0.5 lb. During the process heat transfer to the refrigerant from its surrounding is 1.2 Btu while the work done by the refrigerant is 4.32 Btu. There are no significant kinetic and potential energy effects. • Determine the final temperature of the refrigerant in F •Determine the initial and final specific volume. • Diagram sketch of the P-v include critical point data
