Heat energy transferred to a substance can raise the temperature of the substance and result in a change in state (or phase). In this report it will be shown how heat energy consistently being transferred to a frozen substance results in the raising of its temperature, thus the ice melting. I will also show how removing heat energy from a substance continually results in lowering its temperature in turn freezing it. The objective of this report is to find the value of the latent heat of fusion of ice. The accepted value for the heat of fusion of ice this is 3.33 x 10^5 Joules/kg.

To figure this out ice is added to warm water in an aluminum cup, with a calorimeter, then as the equilibrium temperature is reached the initial temperature of the cup and water is recorded, this is done before the ice is added. Then enough ice to cool the water and cup is added and the as the equilibrium temperature was met the final temperature was taken. Using the values of the temperatures as well as the masses, the latent heat of fusion was then able to be calculated.
