A simple, effective apparatus demonstrates the heat conductivity of various metals. Four metal bars (Copper, Aluminum, Brass, and Steel) are mounted on a base with a hole for suspension.
A Heat Conductometer is used for comparing the thermal conductivity of five metals: aluminum, brass, steel, nickel, and copper. The 5 spokes radiate from a brass hub. Each rod is marked on the rods.
Two metals of different heat coefficients, brass and iron are laminated together and mounted in a wooden handle. This device demonstrates the unequal expansion of different metals by bending when heated.
An excellent tool for use in thermal conductivity experiments with a set of rods made with 6 different metals: Iron, Copper, Aluminum, Lead, Brass, and Zinc.
