The length of the two rods made up of the same metal and having the same area of cross-section are 0.6 m and 0.8 m respectively. The temperature between the ends of first rod is `90^(@)` C and `60^(@)` C and that for the other rod is 150 and `110^(@)` C. For which rod the rate of conduction will be greater

A

First

B

Second

C

Same for both

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
C
In steady state heat conduction rate is given as `kA(DeltaT//l)` which comes out to be equal for both rods.
