Mrs. Lowe . April 2011. Chemical changes . Chemical change . is a change that forms a new type of matter . Chemical property . is a feature of matter that can cause a chemical change. Examples of a different type of matter forming during a chemical change. 1.7. Physical Changes. Physical Change. : the substance involved remains the same, even though it may change state or form. . Examples: . Dissolving – stirring a spoonful of sugar in water. Melting –an ice cube melts. and. Changes. By Jordan Parkinson. What are some Physical Properties?.

Chemical Change . – a . change in the molecules . occurs, . cannot be reversed. Physical and Chemical Changes Physical and Chemical Properties Everything around us has physical and chemical properties. Physical Properties Characteristics you can observe without changing the substance into something new. of the heterogeneous system is an important generalization was put forward by American physicist Willard . gibbs. known as phase rule. It is mathematically represented as F=C-P+2. where F=. Control of Microbes . Chapter 11. 11.1 Controlling . Microorganisms. A. General Considerations in Microbial Control. 1. . .
