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 :

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 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)?
