Thermal Conductivity Demonstration Apparatus for Various Metals

Thermal Conductivity Demonstration Apparatus for Various Metals

Designed to illustrate the relative thermal conductivity of five metals — aluminum, brass, copper, nickel, and steel — this apparatus provides a clear, visual demonstration of heat transfer through different materials. The device features radiating rods made from these metals, mounted on a copper disk that connects them (the whole assembly is attached to a handle). Each rod ends with a recess for placing paraffin. The center of the instrument is heated to drive the demonstration.

Key components and configuration:

• Five metal rods: aluminum, brass, copper, nickel, and steel
• Rods radiate from a copper disk, which connects them together
• Each rod ends with a recess for paraffin placement
• The central heating element heats the middle portion of the device
• The entire assembly is fixed to a handle for ease of use
