On a hot day, you are in a sealed, insulated room. the room contains a refrigerator, operated by an electric motor. the motor does work at the rate of 378 w when it is running. the refrigerator removes heat from the food storage space at a rate of 450 w when the motor is running. in an effort to cool the room, you open the refrigerator door and let the motor run continuously. at what net rate is heat added to (+) or subtracted from (−) the room and all of its contents?

Refrigerant-134a flows through a carnot heat pump cycle at 0.5 kg/s. it is known that the maximum absolute temperature in the cycle is 1.1 times the minimum absolute temperature, and the net power input to the cycle is 2.5 kw. if the refrigerant changes from a saturated vapor to a saturated liquid during the heat rejection process, determine the maximum magnitude of the enthalpy of vaporization for this process in kj/kg (with 3 significant figures).
