What is a gas?

Explanation:
Gas is the state of matter where particles are far apart and can flow to fill the space available to them. At room temperature, a substance becomes a gas if its boiling point is below that temperature, so it readily vaporizes into a gaseous form. If the boiling point is above room temperature, the substance would be a liquid or a solid at room temperature rather than a gas. So the description that matches this concept is a material whose boiling point is below room temperature. Substances with boiling points higher than room temperature would not be gases under those conditions.
