Question

What happens to the air in an air pump when being pumped into a tire? What happens to the air when allowed to escape from a tire?

Answer 1

When air is pumped into a tire, the volume increases without much increase in pressure until the tire reaches its full size and the pressure increases. When air is allowed to escape from a tire, the volume and pressure both decrease.

Step-by-step explanation:

When air is pumped into a deflated tire, the volume of the tire first increases without much increase in pressure. This is because the tire walls limit the volume expansion. However, if we continue to pump air into the tire, the pressure increases. On the other hand, when air is allowed to escape from a tire, the volume decreases, and the pressure decreases as well.

Answer 2

When you pump air into a tire, the gas molecules inside the tire get compressed and packed closer together. This increases the pressure of the gas, and it starts to push against the walls of the tire. You can feel how the tire becomes pressurized and tighter.
