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 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

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)

A slab consists of two parallel layers of copper and brass of the same thichness and having thermal conductivities in the ratio 1:4 If the free face of brass is at 100^(@)C anf that of copper at 0^(@)C the temperature of interface is .

Two rods having thermal conductivity in the ratio of 5 : 3 having equal lengths and equal cross-sectional area are joined by face to face. If the temperature of the free end of the first rod is 100^(@)C and free end of the second rod is 20^(@)C . Then temperature of the junction is
