\nThe specific latent heat of vaporization is defined as the heat energy required to change the state of a unit mass of a substance from liquid to vapour at a constant temperature.
\n<\/section>\n
\nLatent heat is the heat energy absorbed or released during a phase transition (like melting, freezing, vaporization, condensation) at a constant temperature and pressure. Specific latent heat refers to the amount of heat per unit mass. Vaporization specifically refers to the transition from liquid to gas. This phase change occurs without a change in temperature, as the energy is used to break intermolecular bonds.
\n<\/section>\n
\nThere are two main types of specific latent heat: specific latent heat of fusion (solid to liquid or liquid to solid) and specific latent heat of vaporization (liquid to gas or gas to liquid). Each substance has characteristic values for these latent heats.
