Question

Definitions of specific heat and latent heat of fusion and vaporization

Answer 1

Latent heat of vaporization of liquid is defined as the amount of heat required to change the unit mass of liquid at boiling point into vapour at the same temperature. So,latent heat of steam is defined as the amount of heat required to change a unit mass of water from100to steam at the same temperature.
Heat of fusion is the energy needed for one gram of a solid to melt without any change in temperature. Heat of vaporization is the energy needed for one gram of a liquid to vaporize (boil) without a change in pressure.
hope this helps

Answer 2

Answer:

Specific latent heat of fusion :It is the amount of heat energy that is required to melt one kilogram of solid at its melting point, with out any kind of rise in the temperature.

Latent heat of fusion : It is the amount of heat energy absorbed by a solid substance to change into its liquid state without any rise in temperature.

Specific latent heat of vaporisation:It is the amount of heat required to bring a change in unit mass of a liquid at its boiling point without any rise in its temperature.

Latent heat of vaporisation:It is the amount of heat energy absorbed by any liquid to change into gaseous state without any change in temperature.
