Argon gas is initially at a pressure of 10 bar and temperatureof 45oC (state 1), while occupying a volume of 0.8 m3 in africtionless piston-cylinder arrangement. The gas then undergoes areversible constant volume process to a pressure of 6 bar (state2), followed by a constant pressure process in which thetemperature is restored to 45oC (state 3). a) Sketch the processeson T-s and p-v diagrams b) Assuming perfect gas behaviour determinei) The work done by each process. ii) The heat transfer during eachprocess. iii) The change in entropy in process state 3 to 1. (ForArgon take Cp = 519.6 J.kg^-1K^-1 and relative molar mass M=40
