How To Calculate The Heat Of Fusion. The amount of heat gained by a solid object to convert it into a liquid without any further increase in the temperature is known as latent heat of fusion.the content of latent heat is complex in the case of sea ice because it is possible for sea ice and brine to exist together at any temperature and melt at a temperature other than 0 o c when bathed in a concentrated salt solution, just. H = 12 + 14 (10) h = 12 + 140.
{eq}l_f = \frac {q} {m} {/eq} where {eq}l. This value is a constant for a given substance. H = h f + c p δt.
Latent heat is the heat per unit mass required for a phase change to occur. This value is a constant for a given substance. Find the latent heat of fusion, lf, according to lf = q ÷ m by dividing the heat, q, absorbed by the ice, as determined in step 3, by the mass of ice, m, determined in step 4.
The process is better known as the melting and makes the substances little. In this case, lf = q / m = 2293 j ÷ 7.0 g = 328 j/g. Predict the units your answer should have.

Q = ml, which is the required equation for the latent heat of fusion. We may think about what happens when we add ice and cold soda to glass.
Solids should be heated to a point when the molecules holding their bonds start breaking apart and results in liquid ahead. The enthalpy of fusion equation shows that the amount of heat used in causing a phase change is divided by the mass of the matter that is changing phases. Δhf is heat of fusion.
2) δh fus is the symbol for the molar heat of fusion. So, we may expect that the heat from the slightly warmer soda to melt the ice in the glass. H = 12 + 14 (10) h = 12 + 140.
