Five kg of water is contained in a piston–cylinder assembly, initially at 5 bar and 500°C. The water is slowly heated at constant pressure to a final state. The heat transfer for the process is 2660 kJ and kinetic and potential energy effects are negligible. Determine the final volume, in m3, and the work for the process, in kJ. There is no final temperature information given.

Air is contained in a piston-cylinder. Initially, the 0.35 kg of air is at 2 MPa and 350°C. The air is first expanded isothermally to 500 kPa, then compressed polytropically with a polytropic exponent of 1.25 to the initial pressure, and finally compressed at the constant pressure to the initial state. Calculate the net heat transfer during the polytropic process in kJ assuming constant specific heats at 300 K (with 3 significant figures).
