Answer
The pressure inside the soccer ball increases when gas is pumped into it.
Solution
When gas is pumped into a deflated soccer ball, more gas molecules are added, which increases the number of collisions of the molecules with the inner walls of the ball. According to the ideal gas law (PV = nRT), if the amount (n) of gas increases while the temperature (T) and volume (V) are relatively constant (or only slightly change), the pressure (P) inside will increase.
So, the correct answer is: The pressure increases.

As gas is pumped into a deflated soccer ball, the pressure inside the ball increases. This is due to the gas molecules becoming more densely packed together as they fill the available space, which leads to a higher frequency of collisions with the inner surface of the ball. It’s a classic case of how gases behave; they expand to fill their container! If you’ve ever played with a deflated ball, you know the frustration of trying to kick it. But once it’s inflated, it becomes firm and bouncy, thanks to that increased gas pressure. Just think about how much easier it is to score a goal with a properly inflated ball—there’s science in your soccer skills!
