Define the following and state their numerical values in si unit system:A) specific latent heat of fusion of iceB) specific latent heat of vaporization of system

A) Specific latent heat of fusion of ice:
The specific latent heat of fusion of ice, denoted by the symbol L_f, is the amount of heat energy required to convert a unit mass of solid ice at its melting point into liquid water at the same temperature, without changing its temperature.

The numerical value of the specific latent heat of fusion of ice is approximately 334,000 joules per kilogram (J/kg) in the SI unit system.

B) Specific latent heat of vaporization of a substance:
The specific latent heat of vaporization, denoted by the symbol L_v, is the amount of heat energy required to convert a unit mass of a substance from its liquid phase to its gaseous phase at its boiling point, without changing its temperature.

The numerical value of the specific latent heat of vaporization varies depending on the substance. For water, which is the most common example, the specific latent heat of vaporization is approximately 2,260,000 joules per kilogram (J/kg) in the SI unit system.
