Description and Specification for Lab Tenders
Ring and Ball Apparatus.
Ring & Ball Apparatus is used for demonstrating thermal expansion of
metal. The ball expands due to increased molecular motion. When the
Ring and Ball both are at same temperature the ball easily passes
through the ring. Heat the ball in a flame. Try to pass the ball through
the ring, it will not pass. The Ring & Ball Apparatus is a physics
lab equipment used to teach heat, temperature and thermodynamics.
