What is the temperature of the junction of an iron bar (L1 = 0.1 m, A1 = 0.02 m2, K1 = 79 W ${{m}^{-1}}$ ${{K}^{-1}}$ ) and a brass bar (L2 = 0.1 m, A2 = 0.02 m2, K2 = 109 W ${{m}^{-1}}$ ${{K}^{-1}}$ ) when their free ends are maintained at 373 K and 273 K respectively?

Question

What is the temperature of the junction of an iron bar (L1 = 0.1 m, A1 = 0.02 m2, K1 = 79 W

{{m}^{-1}}

{{K}^{-1}}

) and a brass bar (L2 = 0.1 m, A2 = 0.02 m2, K2 = 109 W

{{m}^{-1}}

{{K}^{-1}}

) when their free ends are maintained at 373 K and 273 K respectively?
