- - - - gas
    - - energy levels:
        
        low energy, particle movement is confined
        
        greater energy, particles move more, slip over one another
        
        high energy, particles move erratically
        
        arrangement of particles:
        
        linear, regular structure
        
        particles can slip over one another, close proximity
        
        random speeds and direction of movement, spaced out
        
        can be condensed because there is available space between particles
  - - - melting
        
        liquid
        
        freezing, solidifying
        
        evaporating
      - subliming
        
        gas
        
        condensing
        
        also subliming
    - - this energy goes to breaking the bonds between particles, or overcoming the intermolecular forces
        
        (breaking bonds is for melting, but you don't break bonds to go from a liquid to a gas because the bonds are already broken. instead, the intermolecular forces which hold together the liquid particles are broken)
      - The stronger the forces of attraction, the more energy is required to break them.
        
        The stronger the forces between particles, the higher its melting and boiling point
