The ideal gas constant is also known as the molar gas constant, the gas constant or the universal gas constant. This constant is written as ideal gas law.[1] The ideal gas law is simply where is pressure, is volume, is the number of moles of gas, and is the ideal gas constant.[2]
, and is a constant of proportionality (constant number that is multiplied on one side of a proportional relationship to make them equal) for theThis constant of proportionality depends on which units are used for the other variables in the ideal gas law equation. Some common values for
are:
This constant is closely related to Boltzmann's constant, (to get the ideal gas constant from Boltzmann's constant, multiply by Avogadro's number: ).
