Refrigerant 134a expands in a piston-cylinder assembly from p₁ = 140 lb/in² and T₁ = 140°F to p₂ = 30 lb/in² and T₂ = 80°F. The mass of refrigerant is 0.44 lb. During the process, the work done by the refrigerant is 4.32 Btu. Kinetic and potential energy effects are negligible. Determine the initial volume of the refrigerant, V₁, in ft³, and the heat transfer for the process, in Btu.
