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

For an ideal heat engine, the temperature of the source is 127^(@)C . In order to have 60% efficiency the temperature of the sink should be _____ ""^(@)C . (Round off to the Nearest Integer)

In a Carnot engine the temperature of source is 1000 K and the efficiency of engine is 70%. What is the temperature of the sink ?

A carnot engine has efficiency of 60%. If the source is at 527^(@)C , then find the temperature of sink.

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

An engine has an efficiency of 1/6 . When the temperature of sink is reduced by 62^(@)C , its efficiency is doubled. Temperature of the source is

A reversible engine converts one-sixth of the heat input into work. When the temperature of the sink is reduced by 62^@C , the efficiency of the engine is doubled. The temperatures of the source and sink are
