Ice at 0^@C is added to 200 g of water initially at 70^@C in a vacuum flask. When 50 g of ice has been added and has all melted the temperature of the flask and contents is 40^@C . When a further 80 g of ice has been added and has all melted the temperature of the whole becomes 10^@C . Find the latent heat of fusion of ice.

Ice at 0^@C is added to 200 g of water initially at 70^@C in a vacuum flask. When 50 g of ice has been added and has all melted the temperature of the flask and contents is 40^@C . When a further 80 g of ice has been added and has all melted the temperature of the whole becomes 10^@C . Find the latent heat of fusion of ice.

A 50 g ice at 0^(@)C is added to 200 g water at 70^(@)C taken in a flask. When the ice has melted completely, the temperature of the flask and the contents is reduced to 40^(@)C . Now to bring down the temperature of the contents to 20^(@)C , find a further amount of ice that is to be added.
