properties of matter

  1. volume
    the volume of an object is the space it takes up
  2. mass
    the amount of matter in an object.  a balance or scale can measure mass
  3. matter
    anything that has mass and volume; the building block of everything
  4. unit of volume for liquid
  5. unit of volume for solid
  6. weight
    how strong gravity pulls on an object
  7. solid form of matter
    particles line up in an organized pattern
  8. liquid form of matter
    the particles move past one another but they remain close together
  9. gas form of matter
    the particles move very rapidly; they are spread out with a lot of empty space
  10. melting point
    the temperature at which a solid turns into a liquid
  11. vaporization
    the change from liquid to gas
  12. condensation
    gas turning into liquid
  13. freezing
    the change from liquid to solid
  14. evaporation
    happens at all temperatures
  15. boiling point
    happens at one temperature
  16. sublimation
    the change from a solid to a gas
  17. physical properties
    do not change the matter but can change its appearance; color, smell, freezing point, boiling point; dissolving sugar in water, cutting grass, ripping shirt, trail mix
  18. chemical properties
    only seen during a chemical reaction; heat of combustion, burning wood, fireworks, changing leaf colors, digestion food;
  19. heat
    the transfer of thermal energy from one piece of matter to another
  20. condensation
    the transfer of thermal energy by particles of matter bumping into each other
  21. insulators
    materials that don't conduct thermal energy well; styrofoam, rubber, wood
  22. convection
    a large group of hot particles can move and transfer thermal energy
  23. conductors
    materials that conduct thermal energy well; most metals, water, glass
