A Carnot engine works as a refrigerator in between `250K` and `300K`. If it acquires `750` calories form heat source at low temperature, then what is the heat generated at higher temperature (in calories)?

A carnot engine works as a refrigrator between 250K and 350K.If it receives 750 cal of heat from the reserviour at lower temperature .Calculate the amount of heat rejected at higher tempertaure.

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 :

Carnot engine working as a refrigerator between 260K and 300K receives 500cal of heat from the freezing chamber. Calculate the heat rejected by it to the higher temperature reservior and also the work done per cycle to operate the refrigerator.

A Carnot engine works between 600K and 300K. The efficiency of the engine is

A Carnot engine works between 600K and 300K. The efficiency of the engine 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
