To determine the latent heat of fusion of ice and compare the value obtained with the accepted value.


The amount of heat needed to raise the temperature of a mass of one kilogram of a substance by one Kelvin is called the specific heat capacity, c ,of the material. To raise the temperature of a mass m by △T degrees, the amount of heat required therefore, Q=mc△T.

  1. Prepare the equipment.
  2. Measure the mass of container, and put little water into the container.
  3. Put the boiling water into the container when it reach the half volume of container.
  4. measure the initial temperature of water, and record data.
  5. Measure the container with water, then calculate the mass of water.
  6. Put the ice into the water.
  7. After the disappear of the ice, measure the mass of the caontainer and calculate the mass of ice.
  8. Measure the final temperature of water and record data.

The specific heat capacity of water: 4.18E3 Jkg-1K-1

The speaific heat capacity of ice: 2.1E3 Jkg-1K-1


     4.18×87.8*(58-46)+0.91*29.3*(58-46)= 8.9*Li+4.18*8.9*46



Our conclusion of the latent heat of fusion of the ice is about 338.5J/g.


I think there are some heat transfer to air. And when we measure the initial temperature, the heat transferred during the time we waiting.

    ice is 0.00 �C without any uncertainty, and therefore, the change in temperature for ice has an uncertainty of 0.05 �C only. Now, using the equations above and the values in Table 2, the latent heat of fusion of ice can be calculated as follows:- Latent heat of fusion of

  2. Experiment to Measure the Heat of Fusion of Ice

    Hf = heat of fusion of ice (J/g) cw = specific heat of water (J/g?C) ?Ti = T2 = difference in temperature between that of the ice and the final temperature of the mixture (?C) ?Qlost = ?Qgained By substituting values of mc, cc, mw, cw, mi, ?T, and ?Ti,, we can solve for Hf.

    In the other hand both of the values for specific heat capacity had a very low percentage uncertainty, 0.165% for the aluminium and 0.164% for the aluminium with the insulator.

    Moreover, the percentage uncertainty of 11% suggests that the determination was done quite accurately as well. However, these are only theoretical assumptions as much energy and heat was transferred to air during the water cooling process. Further, I have to state more weaknesses and limitations of my determination.
