The latent heat of fusion is the amount of heat energy that is required to change 1 kg of a substance from the solid phase to the liquid phase at its melting point, without any change in temperature.

Here are the steps to calculate it:

1. Identify the substance and find its specific heat of fusion. This is usually given in problems or can be found in a reference table. The unit is typically J/g or J/kg.

2. Determine the mass of the substance. This should be given in the problem or can be calculated if you know the volume and density of the substance.

3. Use the formula Q = m * Lf to calculate the latent heat. Q is the heat absorbed or released, m is the mass of the substance, and Lf is the specific heat of fusion.

4. Plug in the values you have and solve for Q. This will give you the amount of heat absorbed or released during the phase change.

Remember, the latent heat of fusion is always absorbed when a substance is melting and released when it is freezing.
