Gas
Gas is a state of matter that has neither a fixed volume nor a fixed shape and is a compressible fluid. A pure gas is made up of individual atoms (e.g. a noble gas like neon) or molecules of either a single type of atom (elements such as oxygen) or from different atoms (compounds such as carbon dioxide). A gas mixture, such as air, contains a variety of pure gases. What distinguishes gases from liquids and solids is the vast separation of the individual gas particles. This separation can make some gases invisible to the human observer.
The gaseous state of matter occurs between the liquid and plasma states, the latter of which provides the upper-temperature boundary for gases. Bounding the lower end of the temperature scale lie degenerative quantum gases which are gaining increasing attention.
High-density atomic gases super-cooled to very low temperatures are classified by their statistical behavior as either Bose gases or Fermi gases. For a comprehensive listing of these exotic states of matter, see list of states of matter.
