Thermal Conduction

Open Ended

The diagram represents the transfer of energy through a metal rod by conduction. Explain how energy is transferred by conduction.

Open Ended

Two metal rods of different lengths are heated with a Bunsen burner, as shown in the diagram. Explain why the end of rod B will take longer to increase in temperature than the end of rod A.

Open Ended

Explain how increasing the thickness of a wall will affect conduction through the wall.

Open Ended

Explain why metals are good conductors.

Open Ended

The table shows the thermal conductivity of four metals. Compare the rate of energy transfer through copper with the rate of energy transfer through iron.
