States of Matter

States of Matter
2
Solids

• Have definite volume, shape and mass
• The particles can only move a little
• The particles vibrate back and forth, but strong
  forces hold them in fixed positions

3
Liquids

• Have definite volume and mass but no shape
• The particles can move around more freely than in
  solids and therefore take the shape of their
  container
• The particles are held together by strong
  attractions to each other so it occupies a
  definite volume

4
Gasses

• Definite mass but no definite volume and no
  definitive shape
• Fill whatever container they are in
• The attractions among the particles are so weak
  that individual particles are quite far apart,
  with spaces among them
• The particles are moving constantly and randomly
  in all directions and spread throughout their
  container no matter what its shape and volume
