Question|Free Expansion |Heat Engine |Refrigerator

Assertion : A room can be cooled by opening the door of a refrigerator in a closed room. Reason : Heat flows from lower temperature (refrigerator) to higher temperature (room).

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 :
