Old homes are sometimes heated with so-called steam radiators. In operation, steam flows through the metal radiator causing the metal surface to become hot, which, in turn, results in heat transfer to the room air. A particular steam radiator has a volume of 0.1416m³ and initially contains dry, saturated vapor at 200 kPa. The inlet and outlet valves on the radiator are then closed, and, as a result of heat transfer to the room, the radiation temperature drops to 311 K. Determine the heat transfer (kJ) from the radiator to the room.
