An engine is working . It takes 100 calories of heat from source and leaves 80 calories of heat to sink . If the temperature of source is `127^(@)` C, then temperature of sink is

A Carnot engine takes 300 calories of heat from a source at 500 K and rejects 150 calories of heat to the sink. The temperature of the sink is

For a heat engine the temperature of the source is 127^(@)C .To have 60% efficiency the temperature of the sink is

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

The source tempreature of a Carnot engine is 127^(@)C . It takes 500 cal of heat from the source and rejects 400 cal to the sink during each cycle. What is the temperature of the sink ?

A Carnot engine draws 500 cal of heat from a source at 500K and rejects 300 cal of heat to the sink. Calculate the temperature of the sink and the efficiency of the engine.

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

A Carnot engine, whose temperature of the source is 400K receives 200 calories of heat at this temperature and rejects 150 calaroies of heat to the sink. What is the temperature of the sink? Also, calculate the efficiency of the engine
