    • reversible
      • A reversible change is a change that can be undone or reversed.
      • If you can get back the substances you started the reaction with, that's a reversible reaction.
      • A reversible change might change how a material looks or feels, but it doesn't create new materials.
      • Examples of reversible reactions include dissolving, evaporation, melting and freezing.

      • Heating
        • Heating can cause an irreversible change.
          • For example you heat a raw egg to cook it. The cooked egg cannot be changed back to a raw egg again.
      • Mixing
        • Mixing substances can cause an irreversible change.
          • For example, when vinegar and bicarbonate of soda are mixed, the mixture changes and lots of bubbles of carbon dioxide are made.
            • These bubbles and the liquid mixture left behind, cannot be turned back into vinegar and bicarbonate of soda again.
      • Burning
        • Burning is an example of an irreversible change.
          • When you burn wood you get ash and smoke. You cannot change the ash and smoke back to wood again.
      • new materials are always formed.
      • it cannot be changed back again.
