for wild plum to become established, and the nutrient enrichment increased fruit production. The branches of wild plum were often pruned or cut back to increase production. Cultivars, Improved and Selected Materials (and area of origin) âBlackhawkâ, âHawkeyeâ, and âDe Sotoâ cultivars are descendents of the wild species (Kindscher 1987).
Determination of chemical properties results in the change of the identity of the substance. Some properties, such as solubility, melting point, boiling point, and density are independent of the amount of. substance being examined. These properties are known as intensive properties and are used to identify a. substance.
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.
