Vedclass · Answer

(B) refrigerator works on the principle of a heat pump. It extracts heat from the inside (the freezer compartment) and rejects it into the surroundings (the room). When the door is kept open,the refrigerator continues to extract heat from the room air and rejects it back into the room along with the heat generated by the compressor motor. Since the compressor does work on the system,the total heat rejected into the room is greater than the heat extracted from it. Therefore,the net effect is an increase in the temperature of the room,making it warm.

If the door of a refrigerator is kept open in a room,will it make the room warm or cool?
