Specific latent heat of fusion and vaporization is a measure of the amount of energy required to change a specific amount of a substance from a solid to a liquid or from a liquid to a vapor without changing the temperature of the surrounding environment.
The specific latent heat of fusion is defined as the amount of heat energy required to convert one kilogram of a substance from a solid to a liquid at a constant temperature. Conversely, the specific latent heat of vaporization is the amount of heat energy required to convert one kilogram of a substance from a liquid to a vapor at a constant temperature.
Here,
L_f is the specific latent heat of fusion
L_v is the specific latent heat of vaporization
These two values are equal because the change in heat energy for a phase transition is the same for all substances. This means that it takes the same amount of energy to melt or vaporize a kilogram of a substance, regardless of its chemical composition.
The specific latent heat of fusion and vaporization is an extensive property that is independent of the temperature. This means that the specific latent heat of fusion and vaporization will be the same for a substance at any temperature, as long as the temperature is kept constant
