Which of the following is not an example of a chemical change?
- Iron Rusting
- Gas Burning
- Breaking a glass
- Burning Wood
Hint:
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.
