A 0.15 kg of air contained in a piston-cylinder device where the initial pressure was 2000 kPa and the temperature was 350°C. The substance has undergone several expansion and compression processes. The air is first expanded at a constant temperature to a pressure of 500 kPa and then compressed polytropically with a polytropic exponent of 1.2 to the initial pressure, and finally compressed isobarically to the initial state. Determine the boundary work for each process and the net work of the cycle.
