Chemical Change: Burning of paper
Explanation:
- Burning of paper is a chemical change because it involves a chemical reaction that results in the formation of new substances.
- When paper is burned, it undergoes a chemical reaction with oxygen in the air, resulting in the formation of ash, smoke, and gases like carbon dioxide and water vapor.
- The original paper is no longer present after burning, and the new substances formed have different chemical properties than the paper.
- This is in contrast to physical changes like boiling water, cutting wood, or shredding paper, where the substances involved remain the same chemically.
- In the case of boiling water, cutting wood, and shredding paper, the physical state or appearance of the substances may change, but their chemical composition remains the same.
- Therefore, the burning of paper is the only example among the given options that represents a chemical change.
