Explain what specific latent heat is
WebA specific latent heat (L) expresses the amount of energy in the form of heat (Q) required to completely effect a phase change of a unit of mass (m), usually 1 kg, of a substance as an intensive property: =. Intensive properties are material characteristics and are not dependent on the size or extent of the sample. ... WebDefinition And The Formula for Specific Latent Heat. Specific latent heat is the amount of energy required to change the state of 1 kg of a substance without changing its temperature. The specific latent heat changes from substance to substance. It can be determined experimentally using the following formula. L = E m.
