  1. Gases behaviors
    You can compress with very little pressure. Do not want to be contained and will escape whenever possible
  2. What happens when a liquid has been sitting in one place for a while
    It becomes a gas.
  3. Gas and energy
    All gases have different energies.
  4. What is plasma?
    Similar to gas, but plasma's electrons and ions are more bouncy.
  5. Plasma example
    Northern Lights
  6. Plasma is
    Super hot! In everyday and night objects.
  7. Superfluids are also known as
    B E condensate (Bose-Einstein condensate)
  8. How were superfluids identified?
    In 1995, two scientists--Cornell and Weiman--made this new state of matter.
  9. Why are superfluids also known as "Bose-Einstein Condensate"?
    Albert Einstein and Satyendra Bose predicted a fifth state of matter.
  10. What are superfluids like?
    Complete opposite on plasma spectrum and are extremely cold. "Like 0 degrees Kelvin cold" (-460 degrees Farenheit). Kelvin 0 is "Absolute zero"
  11. What did Carl Weiman and Eric Cornell use for their superfluids?
  12. What did the process for making a superfluid look like?
    The atoms clumped together into a super blob.
  13. Solutions are. . .
  14. Solutions can be
    solids in liquids, liquids in liquids, gases in liquids, gases in solids, and solids in solids.
  15. A simple solution has
    . . .a solute and a solvent.
  16. Coenerd's (? spelling?) rule
    There is more solvent than solute.
  17. What happens when solvent meets solute?
    • The solute is placed in the solvent and the concentrated solute breaks down.
    • The molecules of the solvent begin to move out of the way to make room for the solute's molecules.
    • The solvent and the solute interact with each other until the concentration of the two is equal throughout.
    • The concentrate of solute will the the same no matter what.
  18. Mixtures are. . .
    everywhere you look. Most things in nature are mixtures.
  19. Mixtures. . .
    • Individual molecules enjoy being together.
    • Bananas contain.
    • There are an infinite number of mixtures.
    • Substance can be separated physically in mixtures.
  20. You can identify matter by . . .
    • Texture
    • odor
    • properties: color, luster, malleability,
    • melting or freezing or boiling point
    • conductivity
    • density
    • solvency
  21. Mass
    How much matter is in an object.
  22. Weight
    How much gravitational force is acting on the object.
  23. Volume
    How much space an object takes up.
  24. Density =
    mass / volume (mass over volume)
  25. K=
