The propagation of heat in solids occurs by conduction. The speed at which the heat spreads varies according to the substance. As regards metal, the speed is high while in other substances such as glass or plastic, it is very low. For this reason metals have been defined good conductors of heat.
Thermal conductivity can be studied thanks to this kit using three temperature sensors. An aluminium rod, a brass rod and a PVC rod, with a temperature sensor connected to each of them, are immersed simultaneously in a glass containing warm water. It is possible to observe the heat propagation speed difference between each rod.
