Gravesande's Brass Ball and Ring Apparatus serves as a practical tool for showcasing thermal expansion concepts and demonstrate the effects of heating a metal. Students can observe the effects of temperature changes on the expansion of a ring and its effect on the passage of a metal ball.
The size of the brass ball is precisely matched to the brass ring, ensuring that even if the ball is significantly warmer or the ring is significantly cooler, the ball will not be able to pass through the ring. However, when both are at the same temperature, the ball is able to pass through the ring.
If the ring is cooled in ice, the ball will be unable to pass through it. Alternatively, if the ball is heated, it will also be unable to pass through the ring. A chain connects the ball and ring, preventing them from becoming detached.
