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.
For example, a physical property of water is that â¦ it freezes at a temperature of 0 degrees Celsius. A chemical property is a characteristic of a pure substance that describes its ability to change into different substances. For example, a chemical property of methane is that it can catch fire and burn in air. Physical properties can be observed or measured without changing the composition of matter.
