The two ends of a metal rod are maintained at temperatures $$1000C$$ and $$1100C$$. The rate of heat flow in the rod is found to be $$4$$ Js−$$1$$. If the ends are maintained at temperatures $$2000C$$ and $$2100C$$, the rate of heat flow will be

Question

The two ends of a metal rod are maintained at temperatures $$1000C$$ and $$1100C$$. The rate of heat flow in the rod is found to be $$4$$ Js−$$1$$. If the ends are maintained at temperatures $$2000C$$ and $$2100C$$, the rate of heat flow will be

Here,  Δ$$T1=110$$−$$100=10$$∘$$CdQ1dt=4Js$$−$$1As$$ the rate of heat flow is directly proportional to the temperature difference and the temperature difference in both the cases is same, i.e. ∆$$T2$$ $$=$$ $$210$$ $$-$$ $$200$$ $$=$$ $$100C$$. So, the same rate of heat will flow in the second case. Hence,  $$dQ2dt=4Js$$−$$1$$

The two ends of a metal rod are maintained at temperatures 100⁰C and 110⁰C. The rate of heat flow in the rod is found to be 4 ${Js}^{- 1}$ . If the ends are maintained at temperatures 200⁰C and 210⁰C, the rate of heat flow will be
