Density as a Characteristic Property. The density of a substance is a characteristic of that substance. Therefore, density is a property that can be used to help identify a substance. Properties used to help identify substances are called characteristic properties. Characteristic properties are not affected by the amount or shape of a substance: A bolt made from iron will have the same characteristic properties as the hull of an iron ship or a piece of iron railing.
Characteristic Properties. A characteristic property helps you identify a substance. Out of all the elements, only copper melts at 1083 oC. Out of all common compounds, only H 2 O has, at a specific temperature, a density of 0.98g/ml (usually rounded to 1). To say that I have 215 g of a substance in my pocket will not help you guess what it is. It may be a diamond, tangerine peels or a bunch of Kleenex. So mass is not characteristic.
