What is the temperature of
the steel-copper junction in the steady
state of the system shown in Fig. 11.15.
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 cross
section of the steel rod is twice that of the
copper rod. (Thermal conductivity of steel
= 50.2 J s^–1 m^–1K^–1; and of copper
= 385 J s^–1m^–1K^–1)
