What is sublimation
Sublimation: The process of converting solid form of a substance directly into vapour form is called sublimation. In sublimation no liquid state is observed. This is a reversible process.
The substances that can undergo sublimation are: camphor, naphthalene,anthracene and ammonium chloride
Latent Heat of Fusion (solid to liquid change):
The heat which is going into ice but not increasing its temperature, is the energy required to change the state of ice from solid to liquid (water). This is known as the latent heat of fusion of ice (or latent heat of melting of ice).
The latent heat of fusion (or melting) of a solid is the quantity of heat in joules required to convert 1 kilogram of the solid (at its melting point) to liquid, without any change in temperature.
