Ice starts forming in lake with water at 0^(@)C and when the atmospheric temperature is -10^(@)C . If the time taken for 1 cm of ice be 7 hours. Find the time taken for the thickness of ice to change from 1 cm to 2 cm

Bottom of a lake is at 0^(@)C and atmospheric temperature is -20^(@)C . If 1 cm ice is formed on the surface in 24 h, then time taken to form next 1 cm of ice is

The ratio of time taken by ice on the surface of ponds or lakes to become triple the thickness is

One kg of ice at 0^(@)C is mixed with 1 kg of water at 10^(@)C . The resulting temperature will be

Ice has formed on a shallow pond, and a steady state has been reached, with the air above the ice at -5.0^(@)C and the bottom of the pond at 40^(@)C . If the total depth of ice + water is 1.4 m , (Assume that the thermal conductivities of ice and water are 0.40 and 0.12 cal//m C^(@)s , respectively.) The thickness of ice layer is

Thickness of ice on a lake is 5 cm and the temperature of air is -20^(@)C . If the rate of cooling of water inside the lake be 20000 cal min^(-1) through each square metre surface , find K for ice .

Most substances contract on freezing . However, water does not belong to this category. We know that water expands on freezing. Further , coefficient of volume expansion of water in the temperature range from 0^(@)C to 4^(@)C is negative and above 4^(@)C it is positive . This behaviour of water shapes the freezing of lakes as the atmospheric temperature goes down and it is still above 4^(@)C . If the atmospheric temperature is below 0^(@)C and ice begins to form at t = 0 , thickness of ice sheet formed up to a time 't' will be directly proprotional to

A layer of ice of 0^(@)C of thickness x_(1) is floating on a pond. If the atmospheric temperature is -7^(@)C . Show that the time taken for thickness of the layer of ice to increase from x_(1) to x_(2) is given by t=(pL)/(2kT)(x(2)/(2)-x_(1)^(2)) where p is the density of ice, k its thermal conductivity and L is the latent heat of fusion of ice.

A layer of ice of thickness y is on the surface of a lake. The air is at a constant temperature -theta^@C and the ice water interface is at 0^@C . Show that the rate at which the thickness increases is given by (dy)/(dt) = (Ktheta)/(Lrhoy) where, K is the thermal conductivity of the ice, L the latent heat of fusion and rho is the density of the ice.
