When a Solid Is Changed to a Liquid Phase, the Solid
Deposition is the phase transition in which gas transforms into solid without passing through the liquid phase. Deposition is a thermodynamic process. The reverse of deposition is sublimation and hence sometimes deposition is called desublimation.

What phase change occurs during evaporation?

Evaporation, like melting or freezing, is an example of a phase change—a change from one physical form of a substance to another. During evaporation, energetic molecules leave the liquid phase, which lowers the average energy of the remaining liquid molecules.

What happens when a solid becomes a gas?

Sublimation is an endothermic phase transition in which a solid evaporates to a gas. Solids that sublimate have such high vapor pressures that heating leads to a substantial vaporization even before the melting point is reached.
