Some facts

  • Pressure determines the force that works perpendicular to the surface. Mathematically, we can write it down in the following way:
    p=FpSp = \dfrac{F_p}{S}
    • pp - pressure,
    • FpF_p - component of force acting perpendicular to the surface,
    • SS - the area on which force is acting.
  • Pressure is scalar.
  • The pressure is usually marked with the letter p or P.
  • The pressure prevailing in the gas-filled vessel is the average force acting on the walls of this vessel. In this sense, the pressure is thus the statistical property.
  • The basic pressure unit in the SI system is pascal, which is equal to the pressure corresponding to the force of one newton acting on the surface of one square meter:
    1Pa=1N1m21 Pa = \dfrac{1 N}{1 m^2}
  • The relationship between pressure, temperature, and volume of perfect gas (i.e. one where the particles do not interact with each other) is described by the Clapeyron's equation:
    pV=nRTpV = nRT
