'Volatility' in the context of the natural sciences is a measure of the speed at which a substance turns into a vapor from a solid or liquid state. Usually, this refers to the liquid to gas phase transition known as evaporation. Thus, volatile substances evaporate faster, and less volatile substances evaporate more slowly.
Although usually applying to liquids, volatility can apply to solid materials such as dry ice (solid carbon dioxide) and ammonium chloride, which can change directly from solid to vapor without becoming liquid, also known as sublimation.
