Particle Arrangement

Particle Arrangement

1. Solid

   • tightly packed
   • regular arrangement
   • vibrate around a fixed position
   • low energy
   • fixed volume + shape
     • cannot be easily compressed

2. Liquid

   • close particles
   • randomly arranged
   • particles move around each other
   • greater energy
   • can move around each other
     • can flow
     • takes the shape of its container
   • fixed volume
   • no fixed shape
   • cannot be easily compressed
     • little free space between particles

3. Gas

   • have no fixed shape or volume
   • can flow
   • completely fills container
     • particles move quickly in all directions
   • can be compressed
     • since particles are far apart with space to move into
   • particles are far apart
   • randomly arranged
   • free space between particles
