Gas | Definition, State of Matter, Properties, Structure, & Facts
WEBGas, one of the three fundamental states of matter, with distinctly different properties from the liquid and solid states. The remarkable feature of gases is that they appear to have no structure at all. They have neither a definite size nor shape, whereas ordinary solids have both a definite size.
Gas - Wikipedia
WEBGas is one of the four fundamental states of matter. The others are solid, liquid, and plasma. [1] A pure gas may be made up of individual atoms (e.g. a noble gas like neon), elemental molecules made from one type of atom (e.g. oxygen), or compound molecules made from a variety of atoms (e.g. carbon dioxide).
Examples of Gases – What Is a Gas? - Science Notes and Projects
WEBMar 23, 2021 · A gas is a state of matter that has no fixed volume or shape. In other words, a gas takes the shape and volume of its container. Gases condense into liquids or ionize into plasma. The particles in a gas are more distant from each other than in liquids. Gas particles may be elements or compounds.

WEBJun 19, 2020 · Matter can exist in one of several different states, including a gas, liquid, or solid state. These different states of matter have different properties, which are illustrated in the figure below. A gas is a state of matter in which atoms or molecules have enough energy to move freely.
