Question

1. What happens when the ball is cold?

pls help me​

Answer 1

Answer:

The first one, which is cold and it slightly shrinks.

Explanation:

Because metals expand on heating.

Here, the second ball expanded on heating and it is not fit enough to enter the ring.

In the case of the first one, as the temperature decreases, gas molecules contract and move around more slowly with less energy. Thus, lower pressure leads to a lower bounce of the ball. That's why a fully-inflated ball might appear deflated if the temperature drops dramatically.

Hope it helps
