Product Overview
Comprised of a metal box with 100 mm sides; the vertical faces of the box are blackened, roughened, varnished, and polished, respectively. The top of the cube is fitted with a rubber stopper with a hole for the insertion of a thermometer (NOT included).
When a lamp is shined onto the differing sides, students can investigate the varying properties of surface finishes by measuring the rate of heat absorption in the water inside. Alternatively, they may then measure the rate at which heat is released from the cube through a given side. The thermal difference between the sides may be as great as 20 times!
