Question

Aiko has a beach ball which is filled with air. She sits on the ball and compresses it. No air comes out of the ball. Complete the sentences to describe the changes to the air inside the ball. Choose from the word list. Each word can be used once, more than once or not at all. [ increases, decreases, stays the same]

Answer 1

Stays the same.

Step-by-step explanation:

The air inside the ball remains the same because no air came out or went into the ball. However, the pressure of the air inside the ball increased because of the compressive force acting on the ball. The mass of the air remains the same.
