<P> In most usual conditions ( for instance at standard temperature and pressure ) , most real gases behave qualitatively like an ideal gas . Many gases such as nitrogen , oxygen , hydrogen , noble gases , and some heavier gases like carbon dioxide can be treated like ideal gases within reasonable tolerances . Generally , a gas behaves more like an ideal gas at higher temperature and lower pressure , as the potential energy due to intermolecular forces becomes less significant compared with the particles ' kinetic energy , and the size of the molecules becomes less significant compared to the empty space between them . One mole of an ideal gas has a volume of 22.710947 ( 13 ) litres at standard temperature and pressure ( a temperature of 273.15 K and an absolute pressure of exactly 10 Pa ) as defined by IUPAC since 1982 . </P>
