Definitions for "Vapor pressure"
The pressure or tension of a confined body of vapor of a chemical substance in equilibrium with the solid or liquid form of the substance. The pressure of a given saturated vapor is a function of the temperature only, and may be measured by introducing a small quantity of the substance into a barometer and noting the depression of the column of mercury.
The pressure exerted at a given temperature of a vapor in equilibrium with its liquid or solid form.
Pressure imposed by either a vapor or gas.
