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

In a refrigerator, the working substance takes heat $Q_2$ from the sink at lower temperature $T_2$ and gives out a larger amount of heat $Q_1$ to a hot body at higher temperature $T_1$ . Therefore the room gets heated if the door of a refrigerator is kept open.
