Explain the processes of evaporation, condensation, and sublimation.

Evaporation is the process where a liquid changes into a gas or vapor, typically occurring at the surface of the liquid at a temperature below its boiling point.

Condensation is the process by which a gas or vapor changes into a liquid. It is the reverse process of evaporation, often seen when water vapor in the air forms liquid water droplets.

Sublimation is the process where a substance transitions directly from a solid state to a gaseous state without passing through an intermediate liquid phase.
