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.
