A Carnot engine is operated between two heat reservoirs at temperatures of 505 K and 300 K.
a. If the engine receives 6.55 kJ of heat energy from the reservoir at 505 K in each cycle, how many joules per cycle does it reject to the reservoir at 300 K ?
b. How much mechanical work is performed by the engine during each cycle?
c. What is the thermal efficiency of the engine?
