WebThe ideal gas law treats the molecules of a gas as point particles with perfectly elastic collisions. This works well for dilute gases in many experimental circumstances. However, gas molecules are not point masses, and there are many cases gases need to be treated as non-ideal.Johannes D. van der Waals suggested a modification to take into account …
