Question

Which of the following is not an example of a chemical change?

  1. Iron Rusting
  2. Gas Burning
  3. Breaking a glass
  4. Burning Wood

hintHint:

Physical changes are those changes in which an object or matter undergoes a change that does not change its original nature or the chemical composition.

The correct answer is: Breaking a glass


    Breaking of glass is not an example of chemical change.
    • Breaking of glass shows a physical change as the shards are still glass.
    • Since only the external appearance of the glass changes into shards, but the nature of the substance stays the same.
    • It involves no chemical reactions.
