Definition of 'Vapor pressure'
From: GCIDE
- Vapor pressure \Vapor pressure\ or Vapor tension \Vapor tension\ . (Physics) 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.
