An ideal heat engine working between temperature `T_(1)` and `T_(2)` has an efficiency `eta`, the new efficiency if both the source and sink temperature are doubled, will be

An ideal heat engine working between temperature T_(H) and T_(L) has efficiency eta . If both the temperature are raised by 100 K each the new efficiency of heat engine will be

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 ?

The efficiency of Carnot engine when source temperature is T 1 and sink temperature is T 2 will be

A heat engine works between a source and a sink maintaned at constant temperatures T_(1) and T_(2) . For the efficiency to be greatest

A heat engine works between source and sink temperatures 150°C and 30°C respectively.The efficiency of heat engine may be
