A lake is covered with ice 5 cm thick and the atmospheric temperature above the ice is` – 10^(@)C`. At what rate (in cm/hour) will the ice layer thicken? Thermal conductivity of ice `= 0.005` cgs unit, density of ice `= 0.9 g//cc` and latent heat of fusion of ice = 80 cal/g.

Latent heat of fusion of ice : 80 cal/g :: Steam :…………..

The thickness of ice in a lake is 5cm and the atmospheric temperature is 10^(@)C Calculate the time rquired for the thickness of ice to grow to 7cm Therml conductivity for ice =4 xx 10^(-3) cal cm^(-1) s^(-1) c^(-10 density of ice =0.92 g //cm^(3) and latent heat of fusion of ice =80 cal//g .

What is the meant by the statement, 'Latent heat of fusion of ice is 80cal/gm ?

Complete the analogy: Latent heat of fusion of ice : 80 cal/g :: steam:

The thickness of ice on a Jake is 6 cm and the temperature of air is - 10^(@) C . At what rate is the thickness of ice increasing ? Thermal conductivity of ice = 2 "Wm"^(-1) "K"^(-1) . Density of ice = 920 "kg m"^(3) , specific latent heat of ice = 336 "KJ kg"^(-1)

A lake surface is exposed to an atmosphere where the temperature is lt 0^(@)C . If the thickness of the ice layer formed on the surface grows form 2cm to 4cm in 1 hour. The atmospheric temperature, T_(a) will be- (Thermal conductivity of ice K = 4 xx 10^(-3) cal//cm//s//.^(@)C , density of ice = 0.9 gm//ice. Latent heat of fustion of ice = 80 cal//m . Neglect the change of density during the state change. Assume that the water below the ice has 0^(@) temperature every where)
