# Why do ideal gases exist?

May 4, 2016

Why? Because chemists idealize the behaviour of real gases in order to predict their properties.

#### Explanation:

Of course, an ideal gas does not exist except as a conceptual notion, an ideal. Physicists and chemists idealized the behaviour of real gases so that they could explain these phenomena. Under conditions of low pressure and high temperature, all gases behave like real gases, even gases such as $U {F}_{6}$. Idealization is therefore useful.
