  1. 1. (ADAPTED FROM ‘MS. WELLS’ Physical States of Matter
  2. 2. States of Matter <ul><li>Different forms of matter: </li></ul><ul><ul><li>Solid </li></ul></ul><ul><ul><li>Liquid </li></ul></ul><ul><ul><li>Gas </li></ul></ul><ul><li>State depends on 2 things: </li></ul><ul><ul><li>Particle (atoms/molecules) arrangement </li></ul></ul><ul><ul><li>Particle motion </li></ul></ul>
  3. 3. Solid Matter <ul><li>Fixed volume, Fixed shape </li></ul><ul><li>Particles packed together tightly – usually in a repeating pattern </li></ul><ul><li>Examples: wood, glass, salt, plastic </li></ul>
  4. 4. Density <ul><li>What did you notice about the density of </li></ul><ul><li>Solid </li></ul><ul><li>Liquid </li></ul><ul><li>… and Gas? </li></ul>
  5. 6. Solid Matter <ul><li>Particles vibrate in place </li></ul><ul><ul><li>remember – matter is always in motion! </li></ul></ul><ul><li>Want to separate the particles in a solid? BREAK it! </li></ul>
  6. 7. Liquid Matter <ul><li>Fixed volume, changing shape </li></ul><ul><li>Particles can move from place to place </li></ul><ul><li>Particles attracted to each other, but more easily separate </li></ul><ul><li>Take the shape of the container its put in </li></ul><ul><li>Examples: milk, oil, honey, water </li></ul>
  7. 8. Gas Matter <ul><li>Volume changes , shape changes </li></ul><ul><li>Examples: air, oxygen, water vapor </li></ul><ul><li>Particles always push outward on container </li></ul><ul><ul><li>Spread to fill container if there is more space </li></ul></ul><ul><ul><li>Or pack closer together when there is less space = PRESSURE from the pushing! </li></ul></ul>
  8. 10. Pressure: Gases and Temperature <ul><li>Increased temperature (add heat) </li></ul><ul><ul><li>Particles speed up </li></ul></ul><ul><ul><li>(more energy) </li></ul></ul><ul><ul><ul><li>= Volume increases! </li></ul></ul></ul><ul><li>Decreased temperature </li></ul><ul><li>(remove heat) </li></ul><ul><ul><li>Particles slow down </li></ul></ul><ul><ul><li>(less energy) </li></ul></ul><ul><ul><li>= Volume decreases! </li></ul></ul>
  9. 11. Example: water <ul><li>1. Solid phase. What is the freezing/melting temperature of water? What is solid phase of water called? </li></ul><ul><li>2. Liquid phase. </li></ul><ul><li>3. Gas phase. What is the gas phase of water called? </li></ul><ul><li>What is the boiling temperature of water? </li></ul>
  10. 13. Celsius scale <ul><li>0 degrees Celsius = freezing point of water </li></ul><ul><li>Absolute zero =coldest possible temperature </li></ul><ul><li>All motions cease at absolute zero </li></ul><ul><li>The temperature at absolute zero = -273 degrees C. </li></ul>
  11. 14. Kelvin <ul><li>0 degrees K = absolute zero </li></ul><ul><li>273 degrees K = 0 degrees C. </li></ul><ul><li>10 degrees C = 283 degrees K. </li></ul>
  12. 15. Quiz <ul><li>1. Is the density of water higher in liquid or solid phase? </li></ul><ul><li>2.If the density of solid water were higher than liquid, what would happen to a lake when it freezes over during winter? </li></ul><ul><li>3. 1 degree C is ____ degrees K. </li></ul>
