Vapor
What is Vapor?
Vapor is the gaseous phase of a substance that is normally found as a liquid or solid below its critical temperature, capable of being condensed into a liquid by applying pressure at constant temperature. The vapor pressure of a liquid is the pressure exerted by the vapor in dynamic equilibrium with the liquid at a given temperature, and it increases with temperature according to the Clausius-Clapeyron equation. Understanding vapor behavior is essential in distillation, meteorology, and the design of chemical processes.
