A metal ball is just able to pass through a metal ring. When Anette increases the temperature of the ball, however, it will not pass through the ring. What would happen if she instead increased the temperature of the ring, rather than the ball? Discuss whether the size of the hole increases, stays the same, or decreases.

The size of the hole will increase

Explanation:

Heat is a form of energy that depends to a great extent on the temperature of the system, when a solid is heated there will be increases in it's length, area and volume otherwise known as linear, beta and superficial expansivities respectively. When Annette increased the temperature of the ring she supplied heat to the ring that led to the expansion of the ring, what really happened was that she increased the area expansivities of the ring which is the increase in area per unit area per degree rise in temperature, at such the interior diameter of the ring increase to such an extent that the ball passes through it.
