In a frictionless piston-cylinder arrangement, an ideal gas undergoes a compression process from an initial state of 1 bar at 300 K to 10 bars at 300 K. The entire process comprises the following two mechanically reversible processes:

(a) Cooling at constant pressure followed by heating at constant volume (b) Heating at constant volume followed by cooling at constant pressure. Calculate Q, AU and AH for the two processes, given that Cp = 29.10 kJ/kmol-K, Cy = 20.78 kJ/Kmol-K and volume of the gas at initial state equal to 24.942 m/kmol.
