Solution

Melting
Freezing
The gradual change of state from solid to liquid by absorbing heat from surroundings is called Melting. Gradual Change of state from liquid to solid by leaving heat in the surroundings is termed freezing.
The temperature at which a solid transforms into liquid is called the melting point of the concerned substance The temperature at which a liquid transforms into a solid by leaving heat is termed as Freezing point of the concerned substance.
Heat is required to supply from an external source for such a change of state. Heat is required to take away from the substance for this change of state.
The volume of substance usually increases due to melting The volume of substance usually decreases due to freezing
Example-
Ice to water
melting of iron ore in furnace
Example-
Water to ice
liquid wax to solid wax.
