Hey here is your answer
14. Boiling point: the temperature at which the liquid starts boiling at the atmospheric pressure is called boiling point.
Melting point: the temperature at which solid starts mellting and becomes a liquid at the atmospheric preasure is called melting point.
Evaporation: the process in which a liquid is converted into vapours at any temperature below it's boiling point is called evaporation.
15. Latent heat of fussion: the amount of heat energy that is required 1 kg of a solid into liquid at atmospheric pressure is called latent heat of fussion.
Latent heat of vapouristion: the amount of heat energy that is required to change 1 kg of a liquid at atmospheric pressure is called latent heat of vapourisation.

Boiling point : It is a particular temperature at which any liquid starts boiling under normal atmospheric pressure.
Melting point : It is a particular temperature at which a solid starts melting under normal atmospheric pressure.
Latent heat of fusion : It is the amount of heat required for the complete conversion of a unit mass of a solid into its liquid state at its melting point.
Latent heat of vaporization : It is the amount of heat required for the complete conversion of a unit mass of a liquid into its gaseous form at its boiling point.
