Question

Quizplus · Accepted Answer

Burning gasoline in a lawnmower is a chemical change, not a physical change. During burning, molecules of gasoline combine with oxygen from the air to form new substances, like carbon dioxide and water vapor. This is a chemical reaction, and the original molecules of gasoline are no longer present. In contrast, the other options listed involve physical changes, where the substances involved may change their physical state, but their chemical composition remains the same.
