Specific latent heat is the energy needed to change the state of a substance.
What is Specific latent heat?
Specific latent heat is the energy needed to change the state of a substance. Latent heat is the energy absorbed or released by a substance during a change in its physical state. The latent heat is normally shown as the amount of heat energy in joules per Kg mass of the substance undergoing the change of state.
Specific latent heat equation
To calculate Specific latent heat we use this equation.
$E = {\text{m} \text{L}}$
