Which term is a property that does not depend on the amount of material and helps identify a substance?

• A. Density
• B. Characteristic Property
• C. Mean
• D. Median

Answer: (B)

A property that stays the same no matter how much material you have and helps identify what the substance is is called a characteristic property. This kind of property is intrinsic to the substance and remains constant under a given set of conditions, so you can measure it with a tiny sample or a large one and get the same result. That consistency makes it useful for identifying substances. Examples include melting point, boiling point, density at a standard temperature and pressure, and refractive index. By contrast, mean and median are ways to summarize data and depend on how much data you collected, not on the material itself.
