PPT-Chemical Changes and Properties

Chemical Property describes the ability of a substance to undergo changes in identity Chemical Change changes the identity of a substance products have different properties Signs of a Chemical Change. Physical Science Notes. Physical Properties. PHYSICAL PROPERTY . - A feature or characteristic of matter which can be observed without changing the identity of the matter . Examples. :. . . Color. 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. Matter. Every element/compound is unique in some way from all others.. If you know enough about a substance, you can figure out what it is.. If you know what a substance is, you can know all types of things about it.. 21. Physical Properties. Chemical Properties.
