In chemistry, volatility is a material quality which describes how readily a substance vaporizes. At a given temperature and pressure, a substance with high volatility is more likely to exist as a vapour, while a substance with low volatility is more likely to be a liquid or solid. Volatility can also describe the tendency of a … See more Volatility itself has no defined numerical value, but it is often described using vapor pressures or boiling points (for liquids).
