Specific latent heat of vaporization si unit
WebLatent heat of fusion, also known as enthalpy of fusion, is the amount of energy that must be supplied to a solid substance (typically in the form of heat) in order to trigger a change in its physical state and convert it into a liquid (when the pressure of the environment is kept constant). For example, the latent heat of fusion of one ... WebThe specific latent heat ( L) of a material… is a measure of the heat energy ( Q) per mass ( m) released or absorbed during a phase change. is defined through the formula Q = mL. is often just called the "latent heat" of the material. uses the SI unit joule per kilogram [J/kg].
