A Carnot engine is operated between two heat reservoirs at temperatures of 530K and 300K.
Part A If the engine receives 6.50kJ of heat energy from the reservoir at 530K in each cycle, how many joules per cycle does it reject to the reservoir at 300K ?
Part B How much mechanical work is performed by the engine during each cycle?
Part C What is the thermal efficiency of the engine?
