Conduction

Heat energy can move through a solid by conduction. We can show this in 2 ways:

Illustrative background for WaterIllustrative background for Water ?? "content

Water

  • An ice cube is at one end of a test tube and water is at the other end of a test tube.
  • We can boil the water at one end without the ice cube melting.
  • This shows that water is a poor conductor of heat energy.
  • We say that water is a bad thermal conductor.
Illustrative background for Metal rodsIllustrative background for Metal rods ?? "content

Metal rods

  • Different metals conduct heat energy at different rates.
  • We place metals in boiling water at one end and put wax on the other end.
  • The wax that melts fastest will be attached to the metal that is the best thermal conductor.
  • Copper is a better thermal conductor than aluminium and iron.
