  1. Matter that has a definate shape and definite volume
    Solid
  2. matter that has a definite volume but does not have a definite shape
    Liquid
  3. Matter that does not have a definite shape or definite volume
    Gas 
  4. Particles stay in one place but move quickly back and forth
    Solid
  5. Particles can slide past one another
    Liquid
  6. Particles move freely
    Gas
  7. Characteristic you can observe without changing the identity of the material 
    Physical properties of matter
  8. The amount of matter in an object
    Mass
  9. Gravitational pull of an object
    Weight
  10. Multiply the length, width, and height
    Volume
  11. 6 Physical Properties of Matter
    • 1. Mass
    • 2.  Weight
    • 3.  Volume
    • 4.  Density
    • 5.  Solulibility
    • 6.  Boiling point
  12. Ability of one material to dissolve into another
    Solulibility
  13. Temperature in which a liquid changes to a gas
    Boiling Point
  14. Mass per unit of volume
    Density
  15. The particles in matter  ??????????? one another
    pull to
  16. Characteristic of a material that you can observe as in changes to a different substance
    Chemical property
  17. Describe how iron turns to rust
    When iron reacts with water and oxygen in the air rust is formed.
  18. Changes in state involve changes in the amount of _________that the particles in a substance have.
    energy
  19. What is a sign that a chemical change is involved?
    Energy release
  20. What is ALWAYS conserved during physical and chemical changes?
    Mass
  21. ESSAY:  Explain how you can tell a solid by looking at the molecules.
    The particles in a solid stay in one place, but move quickly back and forth in all directions.
  22. ESSAY:  Explain how to change molecule movement
    You can boil a molecule and it will change to a gas at it's boiling point.  When a molecule changes state, the amount of energy the particles have changes as well. 
  23. ESSAY:  What is the difference between mass and weight?
    Mass is the amount of matter in an object.  Weight is the gravitational pull of an object.
  24. ESSAY:  How is energy involved in a chemical reaction?
    The release of energy is a sign that a chemical change is involved. 
  25. ESSAY:  Explain how physical changes and chemical changes affect mass.
    Mass is always conserved during physical and chemical changes.
