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:
Text Solution
Verified by ExpertsC
The two ends of a rod are maintained at temperatures 
and 
.
Given, 
As the rate of heat flow is directly proportional to the temperature difference and the temperature difference in both cases is same, i.e. 
.
So, the same rate of heat will flow in the second case.
Hence, 
So, if the ends of the rod are maintained at temperatures 
and 
, then the rate of heat flow will remain same,
i.e. 
.
