States of Matter

• solids


  • regular lattice arrangement
  • cannot be compressed
  • fixed position
• Liquids


  No arrangement

  cannot be compressed
• Gas


  particles move at a fast rate

  partciles far apart

  can be compressed
• Solid to liquid


  Melting
• Liquid to gas

  evaporation
• solid to gas


  sublimation
• liquid to solid

  Solidification
• gas to liquid


  condensing
• Energy (thermal) is needed to overcome the electrostatic forces of attraction between particles to attract
