Question

Define latent heat of melting(fusion) .give it's units

Answer 1

The enthalpy of fusion of a substance, also known as (latent) heat of fusion, is the change in its enthalpy resulting from providing energy, typically heat, to a specific quantity of the substance to change its state from a solid to a liquid, at constant pressure.

Answer 2

latent heat of melting or fusion- is the amount of heat absorbed or released when a substance changes from solid to liquid or from liquid to solid without any change in temperature . the specific latent heat of fusion of ice is 336×10 raise to the power 3 j/kg
