Vedclass · Answer

(B) refrigerator is a device that extracts heat from a low-temperature reservoir (the inside) and transfers it to a high-temperature reservoir (the room) by performing work on the system.When the door of an operating refrigerator is kept open,the refrigerator continuously extracts heat from the room and releases it back into the room along with the heat generated by the work done by the compressor.Since the compressor consumes electrical energy and converts it into heat,the total heat rejected into the room is greater than the heat extracted from it.Therefore,the net effect is an increase in the total thermal energy of the room,causing the room temperature to increase.

The door of an operating refrigerator is kept open. As a result,the temperature of the room will
