This 80 mm diameter hollow metal sphere is connected to a manometer (Bourdon) gauge, for demonstrating changes of pressure in a closed volume of air when either heated or cooled. Immersing the ball in a heated water bath or ice bath allows the relationship between pressure and temperature of the enclosed air to be investigated. The metal sphere is more robust than glass versions and responds to temperature changes a little faster.
