A uniform copper bar 50 cm long is insulated on the sides and has its ends exposed to ice and steam respectively. If there is a layer of water 0.1 mm thick at each end, calculate the temperature gradient in the bar at steady state.

Thermal conductivity of copper = 1.04 cgs units

Thermal conductivity of water = 0.0014 cgs units.
