NEET 2015 Physics Heat Transfer MCQ Question
The two ends of a metal rod are maintained at temperatures 100°C and 110°C. The rate of heat flow in the rod is found to be 4.0 J/s. If the ends are maintained at temperatures 200°C and 210°C, the rate of heat flow will be
44.0 J/s
16.8 J/s
8.0 J/s
4.0 J/s
Correct Answer
Detailed Explanation
The rate of heat flow is proportional to the temperature difference. Since the temperature difference remains the same, the rate of heat flow remains 4.0 J/s.
