- 11:07A copper rod and an aluminum rod of equal diameter are joined end to end in good thermal contact. The temperature of the free end of the copper rod is held constant at 100°C, and that of the far end of the aluminum rod is held at 0°C. If the copper rod is 0.24 m long, what must be the length of the aluminum rod so that the temperature at the junction is 50°C? Need Help? Read It Master ItQuestion 4If a copper kettle has a base of thickness 2 mm and area 3 x 10^-2 m², estimate the steady difference in temperature between inner and outer surfaces of the base which must be maintained to enable enough heat to pass through so that the temperature of 1 kg of water rises at the rate of 0.25 K s^-1. Assume that there are no heat losses, the thermal conductivity of copper = 380 Wm^-1K^-1. and the specific heat capacity of water is 4200 Jkg^-1 K^-1.
