Air conditioners operate on the same principle as refrigerators. Consider an air conditioner that has 7.00 of refrigerant flowing during its circuit each cycle. The refrigerant enters the evaporator coils in phase equilibrium, with 54.0 of its mass as liquid and the rest as vapor. It flows during the evaporator at a constant pressure and when it reaches the compressor 95 of its mass is vapor. In each cycle, how much heat is absorbed with the refrigerant while it is in the evaporator? The heat of vaporization of the refrigerant is 1.50×105. Express your answer numerically in joules. =5.15×105 Correct Part B In each cycle, the change in internal energy of the refrigerant when it leaves the compressor is 1.20×105. What is the work done by the motor of the compressor? Express your answer in joules. =1.20×105 Correct Part C If the direction of the refrigerant flow is inverted in an air conditioner, the air conditioning unit turns into a heat pump and it can be utilized for heating rather than cooling. In this case, the coils where the refrigerant would condense in the air conditioner become the evaporator coils when the unit is operated as a heat pump, and, vice versa, the evaporator coils of the air conditioner become the condenser coils in the heat pump. Assume you operate the air conditioner explained in Parts A and B as a heat pump to heat your bedroom. In each cycle, what is the amount of heat released into the room? You might assume that the energy changes and work done through the expansion process are negligible compared to those for other processes through the cycle. Express your answer numerically in joules. =
