Latent heat of vapourisation can be define as the rate by which water is heat to vapourise, it has a difference with evaporation because evaporation occurs directly when the water start heatin while vapourisation always start in a specific temperature
Latent heat of fusion is the heat energy required to convert the substance from its solid form to its liquid form without change in temperature while latent heat of vaporisation of a substance is the quantity of heat required to change the substance from liquid to vapour without change in temperature
The amount of energy needed to change the "state of matter" is termed as "latent heat". This is not same for vapourisation (liquid to vapour) or for fusion (solid to liquid). For example, latent of fusion is 79.7 cal whereas latent heat for vapourisation is 541 calories. The latent depends on how closely the atoms and molecules in the matter are closely packed.
heat of fusion and heat of vapourisation.
It is called latent because heat is supplied without any increase in temperature.
The latent heat of fusion of 1kg water is 334 kJ/kg. (Wikipedia)
latent heat of fusion tells us about the amount of energy that must be taken off from water at 00C to fuse it into ice at 00C . Actually this in this phase temperature remains constant and this energy is (either latent heat of fusion or latent heat of vaporization is the potential energy which is possessed by the states by their virtue.
latent heat of vapourisation is the heat energy required to change 1 kg of a liquid to gas at atmospheric pressure at its boiling point where latent heat of fusion is the amount of heat energy required to change 1 kg of solid to liquid at its melting point so that is why latent heat of vapourisation higher than latent heat of fusion.

the application of latent heat fo fussion is ice is used to put in drinks to make cool because ice has hih specific heat capcity

heat of fusion and heat of vapourisation.
There is no relationship between heat of fusion and heat of vapourisation
It is called latent because heat is supplied without any increase in temperature.
The latent heat of fusion
The latent heat of fusion of 1kg water is 334 kJ/kg. (Wikipedia)
The latent heat of evaporation
They are the same thing. Fusion and solidification both mean the changing of a liquid to a solid.
