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

Options

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

Answer

B

Explanation

The average room temperature in the room will rise because with the door open the temperature will start rise inside the refrigerator.
The thermostat will kick in and try to cool it back down. This means the motor is running, which means heat is being added to the room.
