Question

What happens to the pressure and the molecules inside a football that is

being pumped up?
A. The pressure increases, and the molecules slow down.
B. The pressure decreases, and the molecules collide with the
football's inner surface.
C. The pressure increases, and the molecules collide with the
football's inner surface.
D. The pressure decreases, and the molecules slow down.

Answer 1

When a football is being pumped up, both the pressure and the speed of the molecules inside the football increase.

Step-by-step explanation:

When a football is being pumped up, both the pressure and the speed of the molecules inside the football increase. This is because the air being pumped into the football increases the number of gas molecules present, resulting in a higher pressure. The increased pressure causes the molecules to collide more frequently with the inner surface of the football, increasing the speed at which they move.
