flammability
Answered by GPT 3.5
Yes, those answers are correct. Magnetism, melting point, and hardness are examples of physical properties, whereas flammability is a chemical property. Physical properties refer to characteristics that can be observed or measured without changing the substance's chemical composition, while chemical properties relate to the substance's ability to undergo chemical reactions or changes.
