hey there !!!

Enthalpy, the sum of the internal energy and the product of the pressure and volume of a thermodynamic system. ... Other phase transitionshave similar associated enthalpychanges, such as the enthalpy (or latent heat) of fusion for changes from a solid to a liquid.

Hope it helps !!

all the best !!

❤. The conversion of solid into liquid is called melting or fusion;and the process of conversion of liquid into gas is called vapourisation.These processes are collectively called phase transformations.

❤. The enthalpy change accompanyning the conversion of 1 mole of a solid substancevinto the liquid state at its melting point is called enthalpy of fusion.

❤. The enthalpy change accompanyning the conversion of one mole of a liquid into its vapours at its boiling point is called enthalpy of vapourisation .

❤. Such type of enthalpies are called enthalpy of phase transformations.
