ESSENTIAL UNIT 7 (E07)

(States of Matter and the Gas Laws)

(June 2011)

Unit Statement: Unit seven explores the nature of solids, liquids, and gases as well as changing states of matter. The specific properties of gases are also explored including gas laws such as Boyle’s, Charles’s, Gay-Lussac’s, and the Combined Gas Law.

Essential Outcomes: (must be assessed)

1. The Student Will summarize kinetic theory as it applies to gases and relate the theory to gas pressure. (p. 420-424)

2. TSW identify the factors that determine physical properties of a liquid. (p. 425)

3. TSW relate evaporation and kinetic energy. (p. 426)

4. TSW define the conditions under which a dynamic equilibrium can exist between a liquid and its vapor. (p. 426-429)

5. TSW relate the structure and properties of solids. (p. 431)

6. TSW interpret a phase diagram. (p. 438-439)

7. TSW summarize the three factors which affect gas pressure. (451-454)

8. TSW describe the relationships among the temperature, pressure, and volume of a gas. (456-463)

9. TSW calculate the amount of a contained gas when the pressure, volume, and temperature are specified. (p. 464-466)

10. TSW relate the total pressure of a mixture of gases to the partial pressures of the component gases. (469-471)

Introduced and Practiced Outcomes:

1. The Student Will identify conditions necessary for sublimation. (p. 436)

2. TSW describe the conditions under which boiling occurs. (p. 428)

3. TSW identify the factors that determine the shape of a crystal (p. 429-30)

4. TSW analyze why gases are easier to compress than solids or liquids. (p. 450-451)

5. TSW determine conditions under which real gases are most likely to differ from ideal gases. (p. 467-468)
