On a cold winter dry, the temperature of atmosphere is `-T^(@)C`. The cylindrical dram shown is made of insultating material and it contains water at `0^(@)C`. If `L` is latent heat of fusion of ice, `rho` is density of ice and `K_(R)` is thermal conductivity of ice, the time taken for total mass of water to freeze is

M g of ice at 0^@C is to be converted to water at 0^@C . If L is the latent heat of fusion of ice, the quantity of heat required for the above operation would be

On a cold winter day, the atmosheric temperature is -theta (on celsium scale) which is below 0^(@)C. A cylindrical drum oof height h made of a bad conductor is completely filled with water at 0^(@)C and is kept outside without any lid. Calculate the time taken for the whole mass of water to freeze. Thermal conductivity of ice is K and its laternt heat of fusion is L. Neglect expansion of water on freezing.
