A physical change involves a change in the state, shape, or appearance of a substance without altering its chemical composition. Examples include melting ice, tearing paper, and boiling water. These changes are usually reversible and do not create new substances.

FAQs & Answers

  1. What is a physical change in science? A physical change is a change in the state, shape, or appearance of a substance without altering its chemical composition, such as melting or tearing.
  2. How can you tell if a change is physical or chemical? Physical changes do not create new substances and are usually reversible, while chemical changes result in new substances and are typically irreversible.
  3. Are physical changes reversible? Most physical changes are reversible, such as freezing and melting, since the substance’s chemical identity remains the same.
