The two ends of a metal rod are maintained at temperatures 
and 
. The rate of heat flow in the rod is found to be 
. If the ends are maintained at temperatures 
and 
, the rate of heat flow will be
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Rate of heat flow 
temperature difference between two ends
Here, temperature difference in both case is same (i.e. 
)
So, rate of heat flow will also be same
So,
