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.
On the other hand, it is silly to think of the volume of your swimming pool as being a property at a point. It is a characteristic of the entire swimming pool and that makes it extensive. A particularly important type of intensive property is the specific property, which is always given on a unit mass basis. An example is specific volume, which has units of volume/mass, typically expressed as cubic feet per pound or cubic meters per kilogram.
