Explanation:

A physical change is a change in which the form or appearance changes, but no new substances are formed. The smell of rotten eggs involves a chemical reaction producing hydrogen - sulfide gas. The creation of table salt is a chemical reaction between sodium and chlorine. The green color of the Statue of Liberty is due to a chemical reaction (oxidation) of copper. Dry ice (solid carbon - dioxide) becoming vapor is a phase change from solid to gas without a change in chemical composition.
