Question

On cooling, the ball passes through the ring in the experiment.

• A. True
• B. False

Answer 1

The correct option is A True

1. All forms of matter expand on heating and contract on cooling.
2. At first, the ball is heated, so it expands and does not pass through the ring.
3. Then the ball is kept in a beaker containing cold water and the ball passes through the ring because it has contracted on cooling.
