A uniform copper bar 100 cm long is insulated on side, 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. `K_(Cu)=1.04` and `K_(water)=0.0014` in CGS units.

A uniform copper rod 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 1 mm thick at each end, calculate the temperature gradient in the bar. The thermal conductivity of copper is 436 W m^(-1) K^(-1) and that of water is 0.436 Wm^(-1) K^(-1) .

A uniform steel rod of length 50 cm is insulated on its sides. There is a layer of water of thick ness 0.2 mm at each end of the rod. If the ends of the rod are exposed to ice at 0^(@)C , and steam at 100^(@)C, calculate the temperature gradient in the rod. Thermal conductivities of steel and water are 0.11calcm^(-1)s^(-1) ""^(@)C^(-1) and 1.5xx10^(-3)calcm^(-1)s^(-1) ""^(@)C^(-1)

The densities of ice and water at 0^(@)C and 1 bar are 0.96 and 0.99 gm cm^(-3) respectively. If the percentage of occupied space in ice is x, the the percentage of empty space in water is:
