Question

If the door of a refrigerator is kept open then which of the following is true

• A. Room is cooled
• B. Room is heated
• C. Room is either cooled or heated
• D. Room is neither cooled nor heated

Answer 1

The correct option is B Room is heated

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.

Hence,

option $B$ is correct answer.
