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.
Temperature is also related to the amount of internal energy and enthalpy of a system. The higher the temperature of a system, the higher its internal energy and enthalpy are. Temperature is an intensive property of a system, meaning that it does not depend on the system size or the amount of material in the system.quation 1 indicates that for a fixed volume of gas, the pressure increases with increasing temperature. Pressure is just a measure of the force applied by the gas on the walls of the container and is related to the energy of the system.
