Physical changes of matter involve alterations in the state or appearance of a substance without changing its composition. Four common examples include: 1. Freezing - liquid to solid; 2. Melting - solid to liquid; 3. Evaporation - liquid to gas; and 4. Condensation - gas to liquid. These changes are reversible, and the substance retains its original properties.

FAQs & Answers

  1. What is a physical change in matter? A physical change in matter alters the physical properties such as shape or state without changing the substance's chemical composition.
  2. Are physical changes reversible? Yes, physical changes are typically reversible because they do not affect the substance’s chemical makeup.
  3. How is a physical change different from a chemical change? A physical change affects only the appearance or state of a substance, whereas a chemical change results in the formation of a new substance with different properties.
