Some water at `0^@C` is placed in a large insulated enclosure (vessel). The water vapour formed is puped out continuously. What fraction of the water will ultimately freeze, if the latent heat of vapourization is seven times the latent heat of fusion?

What is latent heat of fusion ? Give its value for water.

The specific latent heat of fusion of water is :

What are the values of specific latent heat of melting of ice and specific latent heat of vaporization of water ?

A non conducting vessel thermally insulated from its surroundings, contains 100 g of water 0^(@)C . The vessel is connected to a vacuum pump to pump to water vapour. As a result of this, some water is frozen. If the removal of water vapour is continued, what is the maximum amount of water that can be frozen in this manner? Laten heat of vaporisation of water =22.5xx10^(5)Jkg^(-1) and latent heat of fusion of ice =3.36xx10^(5)Jkg^(-1)

A thermally isolated vessel is maintained inside at 0^@C and contains 200 g of water. When the air above the water is pumped out, some of the water freezes while rest of it evaporated at 0^@C itself. Determine the mass of water that freezed. Take, Latent heat of vapourisation of water at 0^@C = 2.19 xx 10^3 J//g Latent heat of fusion of ice = 3.36 xx 10^2 J//g
