.A gas that behaves exactly as the kinetic theory says is an ideal gas
(eye-DEE-uhl GAS). There are no ideal gases, however, only real gases.
Under ordinary conditions, real gases behave almost like ideal gases. Under
conditions of low temperature and high pressure, gases do not behave as
described in the kinetic theory. Hydrogen and helium are two gases that
behave most like ideal gases under most conditions.
