    Vapor Pressure common Liquids - Engineering ToolBox

    The vapor pressure of a liquid is defined as the pressure exerted by the molecules that escapes from the liquid to form a separate vapor phase above the liquid surface.. The pressure exerted by the vapor phase is called the. vapor or saturation pressure; Vapor or saturation pressure depends on temperature. If a fluid consist of more than one component (a solution), components with
