Burning is a chemical change. During burning, a substance reacts with oxygen, leading to the formation of new substances, such as carbon dioxide and water, and the release of energy. Unlike physical changes, chemical changes result in new materials with different properties.

FAQs & Answers

  1. What is the difference between a physical change and a chemical change? A physical change affects the form or appearance of a substance without creating a new substance, while a chemical change produces new substances with different properties.
  2. Why is burning considered a chemical change? Burning is considered a chemical change because it involves a reaction with oxygen that produces new substances like carbon dioxide and water, releasing energy.
  3. Can burning be reversed like physical changes? No, burning cannot be reversed easily because it produces new substances, unlike physical changes which are usually reversible.
