What term describes a property that can be observed or measured without changing the substance?

• A. Physical Property
• B. Chemical Property
• C. Physical Changes
• D. Chemical Changes

Answer: (A)

Physical properties are characteristics you can observe or measure without altering the substance's chemical identity. This includes attributes like color, density, melting point, boiling point, and hardness. Because these measurements do not involve forming a new substance, the material remains unchanged. In contrast, chemical properties involve how a substance behaves in reactions and would change its composition (for example, flammability or tendency to rust). So, the term that describes a property you can observe or measure without changing the substance is a physical property.
