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.

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.

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

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 .

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

The slab shown in the figure consists of two parallel layers of cooper anb brass of same thickness and having thermal conductivites in the ratio 4 : 1 . IF the free face of the brass is at 100^(@)C and that of copper is at 0^(@)C , then the temperature of the interface will be
