        PHYSICAL CHANGE:

         The  changes  that  occur  only  in  the  physical  properties  of  a  substance  and  no  new

           substance is formed.E.g., Change of state of matter, mixing of two substances, etc.
         During physical changes, the properties of a substance remain the same.

         Many times they are temporary and can be reversed. Melting of ice, heating of water are

           such changes.
         Some changes are physical but irreversible. Plucking of leaves, tearing of papers, breaking

           of glass are such changes.







































         Characteristics of Physical Changes:

               No new substance is formed.
