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 maintaind at temperatures `200^(@)C` and `210^(@)C`, the rate of heat flow will be :

A

16.8 J `//`s

B

8.0 J`//`s

C

4.0 J`//`s

D

44.0 J`//`s

Text Solution

Verified by Experts

The correct Answer is:
C
As the rate of heat flow is directly proportional to the temperature difference and the temperature difference in both the cases is same i.e. `10^@C`
Hence, the same rate of heat will flow.
