Answered by GPT-4o mini
Rusting iron in water is a chemical change. This process involves the reaction between iron, oxygen, and moisture to form iron oxide, commonly known as rust. During rusting, the chemical composition of the iron is altered, resulting in new substances with different properties. In contrast, a physical change would involve alterations that do not change the chemical composition of the material.
