Argon gas is initially at a pressure of 10 bar and temperature of 45oC (state 1), while occupying a volume of 0.8 m3 in a frictionless piston-cylinder arrangement. The gas then undergoes a reversible constant volume process to a pressure of 6 bar (state 2), followed by a constant pressure process in which the temperature is restored to 45oC (state 3). a) Sketch the processes on T-s and p-v diagrams b) Assuming perfect gas behaviour determine i) The work done by each process. ii) The heat transfer during each process. iii) The change in entropy in process state 3 to 1. (For Argon take Cp = 519.6 J.kg^-1K^-1 and relative molar mass M=40

. An ideal gas initially contained at 1 bar and 25ºC, is compressed to a final state of 5 bar and 25ºC. Although the initial and final temperatures are the same, the process is NOT isothermal. Rather, the change of state occurs in two steps. First, the gas is cooled at constant pressure (i.e., 1 bar). Second, the gas is heated at constant volume. Please calculate Q, W, DU, and DH for the two steps. Note: Cp*=29.1 J/mol/K, and 1...
