If the doors of a refrigerator kept in the refrigerator are left open, then

If the doors of a refrigerator kept in the room are left open, the room will gradually get heated. A refrigerator works by removing heat from its interior and releasing it to the surrounding environment through coils at the back or bottom. When the door is left open, the refrigerator’s cooling system continuously tries to cool the entire room, an impossible task, causing the compressor to run constantly. This results in the refrigerator’s motor generating more heat than it can remove. The heat dissipated from the motor and coils will ultimately increase the room’s temperature. Additionally, the heat expelled by the refrigerator is greater than the cooling effect it produces because of inefficiencies in the refrigeration process. Consequently, the net effect of leaving a refrigerator door open in a room is an increase in the room’s temperature. Therefore, the correct answer is [C] The room will gradually get heated.
