Freezing is not a chemical change; it's a physical change. In freezing, a substance changes from liquid to solid state, but its chemical composition remains the same, unlike in a chemical change where the substance's structure is altered.

FAQs & Answers

  1. What is the difference between a chemical change and a physical change? A chemical change alters the chemical composition of a substance, forming new substances, whereas a physical change affects the form or state without changing the chemical structure.
  2. Why is freezing classified as a physical change? Freezing changes a substance from liquid to solid but does not change its chemical composition, making it a physical change.
  3. Can physical changes be reversed? Yes, most physical changes, like freezing and melting, can be reversed by changing the conditions such as temperature.
