Ring & Ball Apparatus Manufacturer,Supplier and Exporter in India
Product Code : ILS-PLE-10131
Indian Lab Suppliers supplies the Ring & Ball Apparatus (Product ID: 10131) as part of its physics lab equipment range. It shows that a metal ball expands when heated, using a ring that the cold ball just passes through.
Quick Answer
At room temperature the metal ball slips through the ring. Heat the ball in a flame and it no longer passes, because its diameter has increased. Once the ball is back at the same temperature as the ring, it passes through easily again. The expansion happens because the atoms vibrate more strongly at higher temperature and their average spacing grows. Take care with the flame and let the hot ball cool before touching it.

Why Buy from Indian Lab Suppliers
Indian Lab Suppliers is an India-based laboratory equipment manufacturer and exporter supplying this ring and ball apparatus alongside its wider physics lab equipment range, with documentation such as a Certificate of Origin available on request for institutional and export orders.
Frequently Asked Questions
Why does the hot ball not pass through the ring?
Heating increases the ball’s diameter, so it becomes larger than the ring opening.
Will it pass again after cooling?
Yes. When ball and ring are at the same temperature, the ball passes through easily.
What heat source is needed?
An ordinary laboratory flame. Handle the flame and the hot metal with care.
