A Carnot's engine works as refrigerator between 250 K and 300K. It receives 500 cal heat from the reservoir at the lower temperature. The amount of work done in each cycle to operate the refrigerator is :

Find relation between efficiency (eta) of carnot engine and coefficient of performance (eta^( )) of refrigerator.

A carnot engine absorbs 1000J of heat energy from a reservoir at 127^(@)C and rejecs 600J of heat energy during each cycle. Calculate (i) efficiency of the engine, (ii) temperature of sink, (iii) amount of useful work done per cycle.

A carnot engine absorbs 500J of heat from a reservoir at 227^(@)C and rejects of seek (ii) efficiency of engine (iii) amount of useful work done per cycle.

Assertion : Efficiency of a Carnot engine increase on reducing the temperature of sink. Reason : The efficiency of a Carnot engine is defined as ratio of net mechanical work done per cycle by the gas to the amount of heat energy absorbed per cycle from the source.

The efficiency of Carnot engine is "0.6" . It rejects "20J" of heat to the sink. The work done by the engine is
