States of matter

• Solids?


  strong forces of attraction between particles which holds them close together in a fixed position of form a regular lattice arrangement

  particles don’t move so have a definite shape and volume

  the particles vibrate about their positions
• Liquids?


  weak forces of attraction between particles

  they are randomly arranged and free to move

  they have definite volume but not shape
• Gas?


  the force of attraction is very weak between the particles

  they are free to move

  it doesn’t have a difinite shape or volume
