The door of an operating refrigerator is kept open. As a result, the temperature of the room will
- A remain unchanged
- B increases
- C decreases
- D depends on the contents inside the refrigerator
Answer & Solution
Correct Answer
(B) increases
Step-by-step Solution
Detailed explanation
A refrigerator is a heat engine which extracts heat from low temperature reservoir and transfer it to high temperature. If a refrigerator's door is kept open, then room will become hot, because in this situation, refrigerator exhaust more heat into the room than earlier. Hence,…
