The State of Gases

The Ideal Gas Law relates the macroscopic properties of ideal gases. It is a good approximation for many gases under standard conditions.

The Equation

PV = nRT
  • P = Pressure
  • V = Volume
  • n = Amount of substance (moles)
  • R = Ideal Gas Constant
  • T = Temperature (must be in Kelvin)
