Hai suhas, i m goutham harsha

The answer is that, the refrigerator actually gives away its heat to the room and gets itself cooled (2nd law of thermodynamix)

so, when u keep it open , it loses more heat and gets itself cooled thus making its surroundings warm....

if my reply is correct, do reward me, if not, give me the correct answer.
