3. The BIG Idea Physical and chemical properties give a substance its unique identity. The matter that makes up a substance can change physically or chemically.

4. Key Concepts 1 Particles of a solid vibrate about a definite position. Particles of a liquid can slide past one another. Particles of a gas move freely within their container. A physical property is a characteristic of matter that you can observe without changing the identity of the substances that make it up. A chemical property is the ability or inability of a substance to combine with or change into one or more new substances. Some properties of matter do not depend on size or amount of the sample. You can identify a substance by comparing these properties to those of other known substances. Lesson 1: Matter and Its Properties

5. Key Concepts 2 Lesson 2: Matter and Its Changes A change in the size, shape, or form of matter in which the identity of the matter stays the same is a physical change. A change in matter in which the substances that make it up change into other substance with different chemical and physical properties is a chemical change. The law of conservation of mass states that the total mass before a chemical reaction is the same as the total mass after the reaction.
