(2) A well-insulated 106 m' room initially at 3°C and 88 kPa is heated by the radiator of a steam heating system. The radiator has a volume of 35 L and is filled with superheated vapor at 300 kPa and 250°C. At this moment both the inlet and the exit valves to the radiator are closed. A 100-W fan is used to distribute the air in the room. The pressure of the steam is observed to drop to 100 kPa after 148 min as a result of heat transfer to the room. Assuming constant specific heats for air at room temperature and that the room is perfectly sealed, the temperature rise will be:
