2. An internally reversible heat engine operates between intake and heat release temperatures between 627 and 27 °C. Part of the work generated by the heat engine is used to move an internally reversible refrigeration machine that works between temperatures of 27 and -23 °C. The heat supplied to the engine is 2100 kJ and the net work output (the work of the engine minus that consumed by the refrigerating machine) is 500 kJ. Detemine a) The heat transferred to the refrigerating machine at -23°c b) The net heat transferred at 27 °C
