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 is defined as mass per unit volume; mathematically, we would write: or mass m density d Volume V = = For any pure substance or homogenous mixture, density is an intensive quantity, which means that its value is the same no matter how much of the substance is present. Density expresses the proportional relationship between mass and volume of the substance. If the density of a particular substance is given in grams per milliliter, it indicates the number of grams present in 1 milliliter of that substance.
