1 Properties of Matter CHAPTER the BIG idea CHAPTER OUTLINE Matter has properties that can be changed by physical and chemical processes. Matter has observable properties. 2.1 Changes of state are physical changes. 2.2 Properties are used to identify substances. 2.3

2 VOCABULARY KEY CONCEPT CHAPTER HOME Matter has observable properties. 2.1 SECTION OUTLINE SECTION OUTLINE density physical property physical change Physical properties can be observed without changing the substance. Physical changes can change some physical properties but do not change the substance. chemical property chemical change

3 VOCABULARY KEY CONCEPT CHAPTER HOME Matter has observable properties. 2.1 SECTION OUTLINE SECTION OUTLINE density physical property physical change Physical properties can be observed without changing the substance. Physical changes can change some physical properties but do not change the substance. Chemical properties describe how substances form new substances. Chemical changes create new substances. chemical property chemical change

4 VOCABULARY KEY CONCEPT CHAPTER HOME physical property 2.1 KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY Matter has observable properties. A characteristic of a substance that can be observed without changing the identity of the substance. density physical property physical change chemical property chemical change

5 VOCABULARY KEY CONCEPT CHAPTER HOME A property of matter representing the mass per unit volume. density 2.1 KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY Matter has observable properties. density physical property physical change chemical property chemical change

6 VOCABULARY KEY CONCEPT CHAPTER HOME A change in a substance that does not change the substance into a different one. physical change 2.1 KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY Matter has observable properties. density physical property physical change chemical property chemical change

7 VOCABULARY KEY CONCEPT CHAPTER HOME A characteristic of a substance that describes how it can form a new substance. chemical property 2.1 KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY Matter has observable properties. density physical property physical change chemical property chemical change

8 VOCABULARY KEY CONCEPT CHAPTER HOME A change of one substance into another substance. chemical change 2.1 KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY Matter has observable properties. density physical property physical change chemical property chemical change

9 VOCABULARY KEY CONCEPT CHAPTER HOME evaporation, boiling melting evaporation Changes of states are physical changes. 2.2 SECTION OUTLINE SECTION OUTLINE freezing freezing point melting point sublimation Matter is commonly found in three states: solid, liquid, and gas. Solid Liquid Gas freezing condensation boiling boiling point condensation

10 VOCABULARY KEY CONCEPT CHAPTER HOME The process by which a substance changes from its solid state to its liquid state. melting 2.2 KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY Changes of states are physical changes. melting evaporation freezing freezing point melting point sublimation boiling boiling point condensation

11 VOCABULARY KEY CONCEPT CHAPTER HOME The temperature at which a substance changes from its solid state to its liquid state through melting. melting point 2.2 KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY Changes of states are physical changes. melting evaporation freezing freezing point melting point sublimation boiling boiling point condensation

12 VOCABULARY KEY CONCEPT CHAPTER HOME The process by which a substance changes from its liquid state into its solid state. freezing 2.2 KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY Changes of states are physical changes. melting evaporation freezing freezing point melting point sublimation boiling boiling point condensation

13 VOCABULARY KEY CONCEPT CHAPTER HOME The temperature at which a substance changes from its liquid state to its solid state through freezing. freezing point 2.2 KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY Changes of states are physical changes. melting evaporation freezing freezing point melting point sublimation boiling boiling point condensation

14 VOCABULARY KEY CONCEPT CHAPTER HOME A process by which a substance changes from its liquid state to its gas state by random particle movement. Evaporation usually occurs at the surface of a liquid over a wide range of temperatures. evaporation 2.2 KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY Changes of states are physical changes. melting evaporation freezing freezing point melting point sublimation boiling boiling point condensation

15 VOCABULARY KEY CONCEPT CHAPTER HOME The process by which a substance changes directly from its solid state to its gas state without becoming a liquid first. sublimation 2.2 KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY Changes of states are physical changes. melting evaporation freezing freezing point melting point sublimation boiling boiling point condensation

16 VOCABULARY KEY CONCEPT CHAPTER HOME A process by which a substance changes from its liquid state to its gas state. The liquid is heated to a specific temperature at which bubbles of vapor form within the liquid. boiling 2.2 KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY Changes of states are physical changes. melting evaporation freezing freezing point melting point sublimation boiling boiling point condensation

17 VOCABULARY KEY CONCEPT CHAPTER HOME The temperature at which a substance changes from its liquid state to its gas state through boiling. boiling point 2.2 KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY Changes of states are physical changes. melting evaporation freezing freezing point melting point sublimation boiling boiling point condensation

18 VOCABULARY KEY CONCEPT CHAPTER HOME The process by which a gas changes into a liquid. condensation 2.2 KEY CONCEPT SUMMARY KEY CONCEPT SUMMARY Changes of states are physical changes. melting evaporation freezing freezing point melting point sublimation boiling boiling point condensation

19 VOCABULARY KEY CONCEPT CHAPTER HOME Properties are used to identify substances. 2.3 SECTION OUTLINE SECTION OUTLINE Physical properties that can be used to identify substances include: density heating properties solubility electric properties magnetic properties Mixtures can be separated by using the properties of the substances they contain.
