The kit includes:

• 1 x Conductivity Star

Find out which metal conducts heat best by placing a small amount of wax at the tip of each rod and heating from beneath in the centre using a tea light candle (not included).  Includes a small block of wax and rods of aluminium bronze, steel, nickel & copper.

• 1 x Thermal Conductivity of Metals Apparatus

Comprising bars of copper, iron, aluminium and brass with nominal thermal conductivities of 395, 72, 240 and 128 Wm-1K-1 respectively, each 80mm x 20mm x 1.5mm, provided with a hollow for wax and mounted on a wooden ring.

• 1 x Ball and Ring Apparatus

Ball and Ring apparatus for demonstrating thermal expansion. The ball will not pass through the ring if it is hot and the ring is cold, but it will pass if both are hot or both are cold.

• 1 x Bi-metallic Strip

For demonstrating the differential expansion of 2 metals by the curvature produced when the strip is heated in a Bunsen flame. Comprises strips of brass and steel, each 200mm x 15mm, riveted together and mounted on a wooden handle.
