Question

define lateran heat of fusion and lateran heat of evaporisation

Answer 1

 The amount of heat energy released or absorbed when a solid changing to liquid at atmospheric pressure at its melting point is known as the latent heat of fusion.

The amount heat required to convert unit mass of liquid into its vapour state without change in its temperature called is latent heat of vaporization. 

Answer 2

Latent heat of evaporisation is when a substance is in liquid state is given energy it change its phases from liquid to vapour,the energy absorbed in this process is called Latent heat of evaporisation.



Latent heat of fusion is the heat absorb by a unit mass of a given solid at its melting point that it converts solid to a liquid at same temperature
