• Changes:
  • Melting: Solid to liquid
  • Boiling: Liquid to gas
  • Condensing: Gas to liquid
  • Freezing: Liquid to solid
  • Subliming: Solid to gas
  • Deposition: Gas to solid
• Solids:
  • Strong forces of attraction between particles
  • Lattice arrangement
  • Keep shape
  • Vibrate around positions
• Liquids:
  • Weak forces of attraction
  • Free to move
  • Closely together
  • Flow to fill container
  • Random motion, constantly moving
• Gases:
  • Very weak forces of attraction
  • Free to move
  • Far apart
  • No shape or volume
  • Constantly moving
