• gas
  • A substance that continues to occupy in a continuous manner the whole of the space in which it is placed, however large or small this place is mad, the temperature remaining constant.
Abstract from DBPedia
    Gas is one of the four fundamental states of matter (the others being solid, liquid, and plasma). 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). A gas mixture, such as air, contains a variety of pure gases. What distinguishes a gas from liquids and solids is the vast separation of the individual gas particles. This separation usually makes a colorless gas 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.

    気体(きたい、英: gas)とは、物質の状態のひとつであり、一定の形と体積を持たず、自由に流動し圧力の増減で体積が容易に変化する状態のこと。「ガス体」とも言う。
