Topic 2 Changes in Matter

Properties of Matter Physical Properties Chemical Properties Are used to describe a substance Chemical Properties Describe how a substance interacts with other substances. Chemical properties are only observable when a chemical change occurs. physical and chemical properties http://www.youtube.com/watch?v=-Ypwtjp0FSE

Properties of Matter Physical Properties

Physical Properties Qualitative Property Quantitative Property A characteristic of a substance that can be described but might not be measured (a quality) Quantitative Property A characteristic of a substance that can be measured numerically (a quantity)

Changes in Matter Physical Changes Chemical Changes A substance changes form but not chemical composition Chemical Changes Causes one or more new substances to be formed. It may be impossible to reverse.

Properties of Matter Physical Changes

Properties of Matter Chemical Changes Reacts with water Reacts with air Reacts with pure oxygen Reacts with acids Reacts with other pure substances Toxicity Stability Combustibility

Identifying Physical and Chemical Changes Look at the following pictures and document whether you think each is an example of a physical or chemical change.

Physical or Chemical Change? It is difficult to determine whether changes are physical or chemical. The following chart will help you decide whether a chemical change has occurred. In order to be completely sure, chemical analysis in a lab must take place.
