Comprised of copper, brass, aluminum, and steel, this apparatus is an effective tool for demonstrating the coefficient of expansion of metals. The rod is placed inside a tube that has both an inlet and outlet for steam. Compare the expanded length of the rod to the temperature difference before and after the rod expands by using a thermometer. The extent of the rod's expansion is measured by a micrometer.
Sold in a case of 10 linear expansion apparatuses.
