(1) Take a few pieces of ice in a glass beaker as shown in figure.

(2) Insert the bulb of a thermometer in ice and measure its temperature.
(3) Put the beaker on a stand and heat the ice using a burner.
(4) Record the temperature using the thermometer after every minute.
(5) As the ice is heated,it starts melting. Stir the mixture of ice and water.
(6) Continue the heating even after ice starts melting.
(7) Draw a graph of temperature versus time.

The specific latent heat of fusion of ice is `80 cal // g` .Explain this statement .

Explanation

What 1g of ice at a pressure of one atmosphere and at a temperature `0^(@)C ` is converted into 1g of water,heat absorbed by the ice is 80 cal.
