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

Answer»

The room would get WARMER! ... If you LEAVE the door open, heat is merely recycled from the room into the refrigerator, then BACK into the room. A net room TEMPERATURE increase would result from the heat of the motor that would be constantly RUNNING to move energy around in a circle.
