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 maintained at temperatures $$200$$°C and $$210$$°C, the rate of heat flow will be :

Question

Infinity Learn · Accepted Answer

Rate of heat flow ∞temperature difference between two ends ⇒dQdt∞(T2-T1)Here$$ temperature difference in both case is same $$(i$$.e.,$$100C). So, rate of heat flow will also be same.So,$$dQdt=4$$ $$J/s$$.

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 maintained at temperatures 200°C and 210°C, the rate of heat flow will be :
