vapor pressure

 

pressure exerted by a vapor. If a vapor is kept in confinement over its liquid or solid so that the vapor can accumulate above the substance with the temperature constant, the vapor pressure reaches a maximum called the saturated vapor pressure. Note: For a specific liquid or solid, at constant volume of vapor above it, the vapor pressure depends only on the temperature.
