(2) A well-insulated 114 m room initially at 4°C and 90 kPa is heated by the radiator of a steam heating system. The radiator has a volume of 40 L and is filled with superheated vapor at 400 kPa and 300°C. At this moment both the inlet and the exit valves to the radiator are closed. A 120-W fan is used to distribute the air in the room. The pressure of the steam is observed to drop to 100 kPa after 146 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: Fan Steam radiator
