Answer :

Solid to Liquid : Melting

Liquid to Gas : Evaporation

A material changes physically when its state changes. They don't involve any alterations to the matter's chemical composition and are reversible. Melting, condensation, vaporization, deposition, freezing and sublimation are a few common state changes.

A substance can transition from a solid to a liquid state through a physical process known as melting or fusing. This happens when the solid's internal energy rises, usually as a result of heat or pressure being applied, which raises the material's temperature to the melting point.

On the surface of a liquid when it transitions into the gas phase, evaporation is a sort of vaporization that takes place. When the rate of evaporation of water is affected by humidity, for example, a high amount of the evaporating material in the surrounding gas considerably slows down evaporation.
