On opening the door of an operating refrigerator kept in a closed room, the temperature of the room will____________________?
Correct answer: B. Increase
- A. Decrease
- B. Increase
- C. Remain same
- D. Increase in summer and will decrease in winter
Explanation
An operating refrigerator removes heat from its interior but rejects that heat plus the compressor's work into the room. With the door open, the net effect is heat addition to the closed room, so its temperature increases.
