Thermal Conductivity Bar


The durable liquid crystal strips embedded in the bars show how a red zone of 40°C moves up the bars. The colours give a dramatic view of conduction. The marked difference in temperature gradients in the bars is also visible. Conduction of heat leaving the metal is shown via immersing the heated bars in cold water. The tops of the bars are designed to be touched with a finger tip to reinforce the colour observations.
