(Q1) A piston-cylinder device contains 3.6 kg of carbon monoxide at 1400 kPa and 370°C is expanded according to the relation PV127 to 140 kPa. Then the gas is compressed isothermally to the initial pressure. Finally, the gas undergoes a constant pressure process to return to the initial state. Determine (a) the temperature after the polytropic expansion, (b) the work done during each process, (c) the net work done of the cycle and (d) the net amount of the heat transfer. C
