The efficiency of a carnot heat engine is 0.6 when the absolute temperatures of the source and sink are T_(1) and T_(2) respectively. The efficiency of another carnot engine is also 0.6 but the source and sink temperatures are different. What are the temperatures of the source and the sink of the other engine ?

A perfect Carnot engine utilises an ideal gas as the working substance. The source temperature is 227^circC and the sink temperature is 127^circC . Find the efficiency of the engine, and find the heat received from the source and the heat released to the sink when 10,000 J of external work is done.

A Carnot engine, having an efficiency of eta= 1/10 as heat engine, is used as a refrigerator. If the work done on the system is 10 J, the amount of energy absorbed from the reservoir at lower temperature is
