Define specific latent heat of fusion.

The value of latent heat of fusion of ice is "______"

A well insulated container has a mixture of ice and water, at 0^(@)C . The mixture is supplied heat at a constant rate of 420 watt by switching on an electric heater at time t = 0. The temperature of the mixture was recorded at time t = 150s, 273s and 378s and the readings were 0^(@)C , 10^(@)C and 20^(@)C respectively. Calculate the mass of water and ice in the mixture. Specific heat of water = 4.2 J g^(-1) .^(@)C^(-1) , Specific latent heat of fusion of ice = 336 J g^(-1) . Assume that the mixture is stirred slowly to maintain a uniform temperature of its content.

Calculate the amount of ice, which is sufficient to cool 45g of water, contained at 30^(@)C , such that the final temperature of the mixture is 10^(@)C . (Take specific latent heat of fusion of ice is 336" J "g^(-1) )
