Two rods of copper and brass having the same length and cross - section are joined end to end. The free end of the copper is at `0^(@)C` and of brass is at `80^(@)C` in steady-state. If thermal conductivity of copper is 4 times of that of brass find the temp. at junction of two rods

Assume the thermal conductivity of copper is 4 times that of brass.Two rods of copper and brass having the same length and cross section are joined end to end.The free and end of copper is at 0°C and the free end of brass is at 100°C.Calculate the temperature of the junctionof thw two rods at equilibirum.

The thermal conductivity of copper is four times that of brass. Two rods of copper and brass of same length and cross-section are joined end to end. The free end of copper rod is at 0^(@)C and that of brass rod at 100^(@)C . Calculate the temperature of junction at equilibrium. neglect radiation losses.

Two rods A and B of same area of cross-section are joined together end to end The free end of the rod A is kept in melting ice at 300 K and free end of B rod at 400 K. The rods are of the same length. The conductivity of A is 3 times that of B. Calculate the temperature of the junction of the rods.

A large cylindrical rod of length L is made by joining two identical rods of copper and steel of length ((L)/(2)) each. The rods are completely insulated from the surroundings. If the free end of copper rod is maintained at 100^(@)C and that of steel at 0^(@)C then the temperature of junction is (Thermal conductivity of copper is 9 times that of steel)

Three metal rods made of copper, aluminium and brass, each 20 cm long 4cm in diameter, are placed end to end with aluminium between the other two. The free ends of copper and brass are maintained at 100 and 0^(@)C respectively. Assume that the thermal conductivity of copper is twice that of aluminium and four times that of brass. The approximately equilibrium temperatures of the copper-aluminiu and aluminium-brass junctions are respectively.
