Ice starts forming in a lake with water at `0^(@)C` when the atmosphere temperature is `-10^(@)C` .If the time taken for first 1cm of ice be formed is 12 minute; the time taken for the thickness of the ice to change from 1cm to 2cm will be:

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

An ice layer of thickness d_1 is floating on a pond of water. The atmospheric temperature is - T^@C . What is the time taken for the thickness of the layer to increase from d_1 to d_2 if L, rho and K are the latent heat of fusion of water, density of ice and thermal conductivity of ice, respectively?

The atmospheric temperature above a lake is below 0^(@)C and constant. It is found that a 2 cm layer of ice is formed in four days. In how many days will the thickness increase to 3 cm?
