Lesson Summary

  • Matter can exist in three different states: solid, liquid and gas.
  • Solids, liquids and gases have unique properties that characterise them.
  • The properties of solids are:
  • ▸ Fixed shape.
  • ▸ Fixed volume.
  • ▸ Not easily compressed.
  • ▸ High or very high density.
  • The properties of liquids are:
  • ▸ Variable shape.
  • ▸ Fixed volume.
  • ▸ Not easily compressed.
  • ▸ High density.
  • The properties of gases are:
  • ▸ Variable shape.
  • ▸ Variable volume.
  • ▸ Easily compressed.
  • ▸ Very low density.
  • Water exists naturally on Earth in all three states – as ice, liquid water and water vapour.
