A vapor initially at 50 psia and 100 F (State 1) is contained within a piston- cylinder device. The refrigerant is cooled at constant volume until its temperature reaches 25 F (State 2) and is then compressed isothermally to a pressure of 45 psia (State 3).

(a) Locate the state points on appropriately labeled P-v and T-v diagrams.

(b) Determine the specific volume (in ft3/lbm), internal energy (in Btu/lbm) and enthalpy (in Btu/lbm) at each state point.
