WebSpecific latent heat of fusion (The heat needed to change the substance from a solid at its melting point into liquid at the same temperature) and specific latent heat of vaporisation … WebSpecific latent heat is the energy that is required to change the phase of a 1 kilogram substance at a steady temperature (thus without causing any change in the temperature). Mathematically, the specific latent heat formula is: L=Q ⁄ M. Where, L = Specific Latent Heat, Q = Heat, M = Mass. The unit of specific latent heat is kJ/kg or J/g.
