An insulated piston-cylinder device contains 0.14 m of saturated refrigerant-134a vapor initially at a pressure of 0.8 MPa. The refrigerant is then allowed to come to equilibrium with the surrounding environment in a reversible manner. The surrounding atmosphere is at 0.4 MPa. a) Sketch a possible process on Pv and Ts diagrams. (Hint: what do you know about the initial and final state if this process is both adiabatic and reversible?)
