What is the process of water changing from liquid to vapour called?

Correct answer: Evaporation

Direct answer: B, evaporation. Evaporation is the change of liquid water into water vapour from the surface of a liquid. Heat gives some surface molecules enough energy to escape into the air. It can occur from oceans, lakes, wet soil, plant surfaces, and an open container, even when water is not boiling. A is the reverse direction: condensation changes vapour into liquid droplets. C, snowfall, is precipitation in the form of snow and is not the name for liquid-to-vapour change. D, melting, changes a solid into a liquid, such as ice becoming water. Therefore the state sequence is liquid water → water vapour, which identifies evaporation. A common confusion is to use boiling for every liquid-to-gas change; boiling occurs throughout a liquid at its boiling point, while evaporation happens at the surface and can occur at lower temperatures. Memory cue: evaporation sends liquid water upward as invisible vapour.
