Description

The apparatus consists of four metal strips, Aluminium, Brass, Copper and Steel meeting together at a central point. The outer end of each strip has a depression into which a small piece of wax is placed. The bunsen flame is directed at the junction and the order of melting demonstrates the thermal conductivity of the metals.
