Name a measurable property used to identify substances.

• A. Color
• B. Odor
• C. Density
• D. Taste

Answer: (C)

Density is a measurable property that helps identify substances because it is an intensive property that doesn’t depend on how much material you have. You determine it by measuring mass and volume and then dividing mass by volume. Since each pure substance has a characteristic density, comparing your measured density to known values lets you tell substances apart, even if they look similar. Color, odor, and taste are also properties you can observe, but they’re qualitative and can change with lighting, temperature, impurities, or personal perception. Taste, in particular, isn’t used for safety reasons, so density provides a more reliable, objective way to identify substances.
