A frictionless piston cylinder is filled with air (0.4 MPa, 17°C). A paddle wheel provides 15,000 J of energy in the form of work. A. Calculate the boundary work: (10

points) B. Calculate the amount of heat transfer: (10 points) C. Sketch a P-V diagram of this process (3 points) D. Confirm that it is correct to assume that air behaves as an ideal gas in this problem. You must pick initial or final conditions. Explain your reasoning for that and show all your calculations.
