Question

Which of the following statements describes a basketball under high pressure (fully inflated) compared to a basketball under low pressure (deflated)?
A In a fully inflated basketball, the particles of gas have lower energy
B. In a fully inflated basketball, the particles of gas collide only with each other.
C. In a fully inflated basketball, the force exerted on the inside of the ball is lower.
D. In a fully inflated basketball, there are more particles of gas.

Answer 1

In a fully inflated basketball, there are more particles of gas.

Answer: Option D.

Explanation:

When a ball is fully inflated, it means it has a lot of air in it. With a lot of air in it, it means that there a lot of gas particles in that ball. With the large amount of gas particles in it, there is a lot of collision among these particles inside the ball.

This collision leads to the pressure on the greater side compared to the ball which has less air in it and is deflated because it has less particles of gas inside.
