Exaplain how this happens, refer to the particles after heating clearly show the size of the ball and before and after heating
When a ball is heated, the particles within the ball gain energy and begin to move faster. This increase in thermal energy causes the particles to spread out further apart, increasing the volume of the ball. As a result, the size of the ball expands.
Before heating, the particles are tightly packed together, with little space between them. This results in a smaller volume for the ball. However, after heating, the particles move more freely and spread out further apart, leading to an increase in volume and size of the ball.
Therefore, heating a ball causes the particles within it to expand and spread out, resulting in an increase in size.
