Chemical properties describe how a substance reacts with other substances to form new substances, indicating the ability of a substance to undergo chemical changes. Examples include flammability, reactivity, and toxicity. Physical properties, on the other hand, describe the characteristics of a substance that can be observed or measured without changing the chemical composition of the substance. Examples include color, size, shape, density, and state of matter. Overall, chemical properties involve the behavior of a substance during a chemical reaction, while physical properties involve the observation of a substance's appearance and behavior without changing its chemical makeup.
