Five characteristics of physical change include: 1) Reversible nature; 2) No formation of new substances; 3) Changes in state of matter (like melting or freezing); 4) Alterations in shape or size; and 5) Energy changes that do not alter chemical composition (like heating or cooling).

FAQs & Answers

  1. What makes a physical change different from a chemical change? A physical change alters the appearance or state of a substance without forming new substances, whereas a chemical change produces one or more new substances with different chemical properties.
  2. Can physical changes be reversed? Yes, most physical changes are reversible because they do not alter the chemical composition of a substance.
  3. What are some common examples of physical change? Examples include melting ice, freezing water, tearing paper, and dissolving sugar in water, where the substance’s composition remains unchanged.
