deposition
Both boiling and evaporation are forms of vaporization. What is the difference between them?
Boiling liquids have intense heat added to it, evaporating liquids take heat from their environment.
Boiling happens quickly, evaporation happens slowly.
Evaporation occurs only at a liquid's surface, boiling occurs throughout the liquid
