Question 345: Properties of Matter

Question

The two ends of a metal rod are maintained at temperatures 100oC and 110oC. The rate of heat flow in the rod is found to be 4.0 J/s. If the ends are maintained at temperatures 200oC and 210oC, the rate of heat flow will be

Accepted Answer

As the temperature difference $$\Delta T$$ = 10ÃÂ°C as well as the thermal resistance is same for both the cases, so thermal current or rate of heat flow will also be same for both the cases.

Answer

8.0 J/s

Answer

4.0 J/s

Answer

44.0 J/s

Answer

16.8 J/s
