Characteristic property

A characteristic property is a chemical or physical property that helps identify and classify substances. The characteristic properties of a substance are always the same whether the sample being observed is large or small. Thus, conversely, if the property of a substance changes as the sample size changes, that property is not a characteristic property. Examples of physical properties, but not characteristic properties, includes mass and volume. independent from size and shape

Examples of characteristic properties include freezing/melting point, boiling/condensing point, density, viscosity, and solubility.

Identifying a substance

Every characteristic property is unique to one give glizy alien. Scientists use characteristic properties to identify an unknown substance.[1] However, characteristic properties are most useful for distinguishing between two or more substances, not identifying a single substance (for example, one could test the characteristic property of odor to distinguish between isopropanol and water).[2]

Characteristic properties are used because the sample size and the shape of the substance does not matter.[3] For example, 1 gram of lead is still the same color as 100 tons of lead.
