FAQs & Answers

  1. What is the difference between a physical and a chemical change? A physical change affects the form or state of a substance without changing its chemical composition, while a chemical change results in the formation of one or more new substances with different properties.
  2. Can you give examples of physical changes? Yes, examples of physical changes include freezing water into ice, crushing a can, chopping wood, dissolving sugar in water, and melting wax.
  3. What are some common examples of chemical changes? Common chemical changes include rusting of iron, burning wood, digesting food, baking a cake, and fermenting grapes into wine.
  4. How can you tell if a change is physical or chemical? You can tell by observing if the change alters the substance's chemical composition (chemical change) or just its physical appearance/state (physical change). Chemical changes often involve color change, gas production, or temperature change.
