Question

On a hot summer day we want to cool our room by opening the refrigerator door and closing all the windows and doors. Will the process work?

Solution

No. When the door of the refrigerator is left open in a closed room, the heat given out by the refrigerator to the room will be more than that taken from the room. Therefore, instead of decreasing, the temperature of the room will increase at a slower rate.

  Is there an error in this question or solution?
