The efficiency of a heat engine if the temperature of source 127∘ C and that of sink is 27∘ C nearly

The efficiency of a heat engine if the temperature of source 227^(@)C and that of sink is 27^(@)C nearly?

The efficiency of a heat engine if the temperature of the source is 100^(@)C and sink is 27^(@)C is nearly

The efficiency of carnot's heat engine is 0.5 when the temperature of the source is T_(1) and that of sink is T_(2) .The efficiency of another crot's heat engine is also 0.5.the temperature of source and sink of the second engine are respecitvely

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 ?

Efficiency of carnot heat engine,if source temperature is T1K and sink temperature is T2K

The efficiency of heat engine is 1/6 when the temperature of sink is reduced by 62^0 C the efficiency doubles. What is the temperature of source?

The efficiency of a carnot engine is (1)/(6) . If the temperature of the sink is reduced by 62 K, the efficiency becomes (1)/(3) . The temperature of the source and the sink in the first case are respectively.
