The radiator of a steam heating system has a volume of 20 L and is filled with superheated water vapor at 200 kPa and 1508C. At this moment both the inlet and the exit valves to the radiator are closed. After a while the temperature of the steam drops to 408C as a result of heat transfer to the room air.
