   * <p>
   * <strong>Gas</strong> is a subclass of
   * {@link adventurejs.Substance|Substance} with gaseous
   * (as opposed to liquid or solid) properties.
   * </p>
   * <h3 class="examples">Example:</h3>
   * <p>
   * Substances are different from
   * {@link adventurejs.Tangible|Tangibles} in that they're
   * semi-global, rather than singular. The class represents
   * all of its kind in a {@link adventurejs.Game|Game},
   * meaning, if you create an instance called "helium", all
   * helium in the Game is the same helium, whether it's in a
   * cylinder or a balloon.
