FAQs & Answers

  1. What makes boiling water a physical change? Boiling water is a physical change because it only changes the state of water from liquid to gas without altering its chemical composition, and this change is reversible.
  2. How can you tell the difference between a physical and chemical change? A physical change affects only the form or state of a substance without changing its chemical identity, while a chemical change results in the formation of new substances with different properties.
  3. Is condensation a physical or chemical change? Condensation is a physical change because it involves the change of water vapor back into liquid water, reversing the phase without altering the chemical makeup.
