6 Air is contained in a piston-cylinder device at 600 kPa and 927°C, and occupies avolume of 0.8 m². The air undergoes and isothermal process until the pressure inreduced to 300 kPa. The piston is now fixed in place and not allowed to move while aheat transfer process takes place until the air reaches 27°C.(a) Sketch the P-V diagram for the combined processes.(b) For the combined processes determine the net amount of heat transfer, in kJ,and its direction (i.e. heat in or heat out).

The radiator of a steam heating system has a volume of 20 L and is filled with superheated water vapor at 200 kPa and 200°C. At this moment both the inlet and the exit valves to the radiator are closed. After a while it is observed that the temperature of the steam drops to 80°C as a result of heat transfer to the room air, which is at 21°C. Assuming the surroundings to be at 0°C, determine the maximum amount of heat that can be supplied to the room if this heat from the radiator is supplied to a heat engine that is driving a heat pump. Assume the heat engine operates between the radiator and the surroundings.
