If a refrigerator's door is kept open,will the room become cool or hot? Explain.

(N/A) If a refrigerator's door is kept open,the room will become hot. $A$ refrigerator works by extracting heat from its interior and rejecting it into the surroundings (the room). When the door is open,the refrigerator continuously extracts heat from the room air and rejects it back into the room,along with the additional heat generated by the compressor's motor work. Since the compressor consumes electrical energy and converts it into heat,the net effect is an increase in the total heat content of the room,causing the temperature to rise.
