force per unit area

Noun
  1. The force applied to a unit area of surface;
    Measured in pascals (SI unit) or in dynes (cgs unit) (synset 111515441)
    "the compressed gas exerts an increased pressure"
    is a type of: physical phenomenon - a natural phenomenon involving the physical properties of matter and energy
    subtypes:
    • blood pressure - the pressure of the circulating blood against the walls of the blood vessels; results from the systole of the left ventricle of the heart; sometimes measured for a quick evaluation of a person's health
    • gas pressure - the pressure exerted by a gas
    • head - the pressure exerted by a fluid
    • hydrostatic head - the pressure at a given point in a liquid measured in terms of the vertical height of a column of the liquid needed to produce the same pressure
    • intraocular pressure, iop - pressure exerted by the fluids inside the eyeball; regulated by resistance to the outward flow of aqueous humor
    • oil pressure - pressure that keeps oil on the moving parts of an internal-combustion engine
    • osmotic pressure - (physical chemistry) the pressure exerted by a solution necessary to prevent osmosis into that solution when it is separated from the pure solvent by a semipermeable membrane
    • corpuscular-radiation pressure, radiation pressure - the minute pressure exerted on a surface normal to the direction of propagation of a wave
    • instantaneous sound pressure, sound pressure - the difference between the instantaneous pressure at a point in a sound field and the average pressure at that point
    • suction - a force over an area produced by a pressure difference
    • vapor pressure, vapour pressure - the pressure exerted by a vapor; often understood to mean saturated vapor pressure (the vapor pressure of a vapor in contact with its liquid form)
    same as: pressure, pressure level
