Physical change of the paint, not the door.
Acidity itself is not a chemical change; rather, it is a property of a substance that reflects its ability to donate protons (H⁺ ions) in solution. However, when an acidic substance reacts with a base, a chemical change occurs, resulting in the formation of new products, such as water and salt. Thus, while acidity can influence chemical changes, it is not a change in itself.
