From, Ice To water ⇒ The amount of the Heat Energy supplied at a constant temperature when Ice will changes to water is called as the Latent heat of Melting.
For water, Latent heat of Melting is 336 kJ/kg.
__________________________
From Water to Vapor ⇒ Also, the amount of the Heat energy required to convert the Water into water vapor at a Constant temperature is called as the Latent Heat of the Vaporization.
For water, It is 2260 kJ/kg.
___________________________
The Formula to Calculate the Latent heat is,
Q = mL,
here m is the mass of the substances undergoing change in the state, L is the Latent Heat, and Q is the amount of Heat energy released.
These Heat energy does not depends upon the temperature, these phenomenon occurs at a constant temperature. During these Changes of state, average kinetic energy does not changes because kinetic energy is the measure of absolute temperature, and it does not changes during these process.
