Which statement describes a chemical change?

• A. It changes state but not composition.
• B. It creates one or more new substances with different properties.
• C. It is easily reversed by simple physical means.
• D. It only occurs when heating water.

Answer: (B)

Chemical change is when a substance becomes something new with different properties. This statement matches that idea because it says one or more new substances with different properties are formed. In contrast, changing state, like ice turning into water, keeps the same material, which is a physical change. And chemical changes aren’t limited to heating water; they happen in many situations, like rusting metal or baking a cake.
