Problem 2 ). Two moles of air is expanded in a piston-cylinder assembly from an initial state of 400 kPa and 341 K to a final pressure of 110 kPa. Assuming ideal gas behavior and a constant heat capacity of Cp =7R/2 calculate Q, W, AH, AU and AS if the expansion is carried out adiabatically and reversibly.
