Given the formula for latent heat which is: Q = mLF In our experiment, we allow the ice to melt in a heated water with a mass of 100g and we calculated its experimental value of latent heat of fusion using the mass of ice. In general, can the mass of the substance affect its latent heat of fusion? Where does the latent heat of fusion of a substance depend on? Is it directly proportional to the mass? Or it is inversely proportional?
