  1. Chapter 3Solids, Liquids, Gas September 16-20, 2013

  2. The Big Idea: Matter has 4 states • IB Question: Are you ready to change? • Essential Question: How does the motion of particles differ in the states of matter?

  3. Georgia Performance Standards • S8P1. Students will examine the scientific view of the nature of matter. • c. Describe the movement of particles in solids, liquids, gases, and plasmas states.

  4. Homework: • T, 9/17—Bibliography and Research Plan due • W, 9/18—Chapter 3 Vocabulary due for all sections • F, 9/20—Study Guide questions complete

  5. Monday DO NOW: • Review your study guide—You have 7 minutes • Clear table for test • Take test • Begin defining chapter 3 vocabulary

  6. Tuesday DO Now: • In your notes design a 4 column chart. Label the columns Solids, Liquids, Gases, and Plasma.

  7. States of Matter Jigsaw • D=Solids, pg. 71-72 • A=Liquids, pg. 73-74 • R=Gases, pg. 75 • E=Plasma, pg. 116 • Read the assigned section. Record words, phrases, and sentences that describe the characteristics of your state of matter. • Teach your group the information for your section.

  8. Ticket Out the Door • How does breathing demonstrate that gases are fluids?

  9. Wednesday DO Now: • Table Talk—Why do ice cubes stored for a long time in the freezer get smaller? • Prepare vocabulary to be checked.

  10. Changes of State • Write a 3 paragraph essay in which you create an analogy (or metaphor) to describe particle motion in the states of matter. • Compare the movements and positions of people dancing, playing football or basketball, etc. with the motions of water molecules in liquid water and in water vapor.

  11. Changes of State • Have a friend edit your essay. • Put your essay in the appropriate box. • Work on study guide if time allows.

  12. Thursday DO Now:

  13. Gas Behavior Measuring Gases • When working with a gas, it is helpful to know its volume, temperature and pressure • Volume • Volume is the amount of space the matter fills. • Measured in cubic centimeter (cm3), milliliters (mL), liters (L), and other units • Volume of a gas = volume of its container

  14. Gas Behavior • Temperature • Temperature is a measure of the average energy of random motion of the particles of a substance • Pressure • The pressure of the gas is the force of its outward push divided by the area of the walls of the container • Pressure= force/area

  15. Pressure and Volume • Boyle’s Law • Boyle found that when the pressure of a gas at constant temperature is increased, the volume of the gas decreases. When the pressure is decreased the volume increases.

  16. Boyle’s law in action • Boyle’s law plays a role in research using high-altitude balloons

  17. Pressure and Temperature • Increasing temperature raises pressure • When the temperature of a gas at a constant volume is increased, the pressure of the gas increases. When the temperature is decreased, the pressure of the gas decreases. • Pressure and temperature in action • (Think of the example of 18-wheel trucks and how they must monitor their tire-pressure on long drives)

  18. Volume and Temperature Charles’s Law • Charles found that when the temperature of a gas is increased at constant pressure, its volume increases. When the temperature of a gas is decreased at constant pressure, its volume decreases.

  19. Charles’s Law in Action

  20. Key Concepts Review • What types of measurements are useful when working with gases? • How are the volume, temperature, and pressure of a gas related?

  21. Friday DO Now:

  22. Graphing Gas Behavior Temperature and Volume • Collecting Data- (As the temperature of the bath increases, the gas inside the cylinder is warmed by the water. Each time the temperature rises, the volume of the cylinder is recorded.)

  23. Graphing Gas Behavior Complete It’s a Gas Skills Lab on page 94-95. • Your lab report must include: • Statement of the problem • Materials List • Procedures • Data Table • Analyze and Conclude requires 2 graphs and has 3 questions to be answered.
