Reversible and irreversible changes


REVERSIBLE AND IRREVERSIBLE CHANGES


•    Changes that occur around us can be broadly categorized as reversible and irreversible depending on whether or not they can be reversed.

•    Ice can be changed back to water by melting and the paper boat can be unfolded to get the sheet of paper; so these are reversible changes.

•    On the other hand, the fruit cannot be changed back to a flower and the chapatti cannot be changed back to dough; so these changes are irreversible changes.

•    Rusting of iron and growth of a plant are examples of irreversible changes.
