Ball and Ring Apparatus Manufacturer,Supplier and Exporter in India
Product Code : ILS-H-10924
Indian Lab Suppliers supplies the Ball and Ring Apparatus (Product ID: 10924) as part of its heat and thermal physics range. This apparatus shows that a metal ball expands when heated: cold it passes through the ring, hot it does not.
Quick Answer
A 19 mm brass ball is held captive to a brass ring by a chain, and the ring is mounted on a rod with a wooden handle. At room temperature the ball just slips through the ring. After the ball is heated in a flame it has expanded enough to rest on top of the ring, and it drops through again as it cools. Hold it by the wooden handle and let the ball cool before touching it.
