               NOTES:

               GASES -

                   •  Gases have no fixed shape and fixed volume.
                   •  They cannot be touched.
                   •  Gases can flow easily. They are also called fluids like liquids.

               In gases the particles are very loosely packed. Thus, there are large spaces
               between the particles in gases, as a result, the particles can move freely in any

               direction.

                Examples: oxygen, carbon dioxide, nitrogen
