- A volatile substance can be defined as (1) a substance that evaporates readily at normal temperatures and/or (2) one that has a measurable vapor pressure. The term volatile usually applies to liquids. However, some solid materials can change directly from solid to vapor without ever becoming liquid, a process called sublimation. The rate at which a substance vaporizes (volatilizes) under a fixed set of conditions is called the evaporation rate.
