This thermal conductivity experiment apparatus features four metal strips fixed to a central metal ring. The metals included are copper (Cu), iron (Fe), brass (Br), and aluminum (Al), each strip engraved for easy identification. Each strip measures 5 inches long and 0.75 inches wide, with the outer diameter of the ring at 4.5 inches. Total dimensions are approximately 10 x 8 x 0.5 inches, with a weight of 0.4 pounds. When the central ring is heated, students can observe and compare the rates of heat conduction through the different metals simultaneously, providing a clear visual demonstration of how thermal conductivity varies among common metals.
