Heat Conductivity Ring Brass Copper Iron AluminiumThe Heat Conductivity Ring of Metals Apparatus enables students to compare the thermal conductivity of four different metals: Copper, Brass, Iron, and Aluminium. Each metal strip is mounted on a circular base with wax depressions, allowing for a visual cue when each metal heats and melts the wax. This hands on approach is ideal for introducing the concept of thermal conductivity in a comparative and measurable way. Mounted on a wooden base for
