describe an experiment to show expansion of solid
Answers
Answer:
Take a ball and a ring .The ball should be of metal. The diameter of the ball should be less than that of the ring. Suspend the ball from a thread. Heat the ball with a Bunsen burner.
Then let it cool down and observe it.
Answer:
The ball and ring apparatus consists of metal ball which fits exactly Through a ring attached to a stand when both are room temperature. Heat the ball using Bunsen burner for a few minutes and then try to pass it through the ring. The ball does not pass through the ring when it is hot. Leave the ball on the ring and allow it to cool for sometime. The ball will now pass through the ring. The hot ball does not through the ring because it has expanded. This proves that solids expands on heating and contract on cooling.
