What is the temperature of the steel-copper junction in the steady-state of the system shown in the figure?
The length of the steel rod = 15.0 cm, length of the copper rod = 10.0 cm, temperature of the furnace = 300 °C, temperature of the other end = 0 °C. The area of the cross section of the steel rod is twice that of the copper rod.
(Thermal conductivity of steel = ; and of copper = ).
