Question

Explain why we have to fill air into a football to inflate it

Answer 1

because it is made to such a design where you need to fill up air so that it gains the shape of a sphere and can be used for the purpose it is made for. This because of the fact that air occupies space....hope it helps..pls mark as brainlist answer....

Answer 2

It is required for proper shape and expansion.

• As the air within the ball exerts pressure, it properly inflates and comes into a spherical shape.
• From the inside, gaseous strain acts on the tiny elastic dividers of the inflatable, typically causing it to sufficiently develop and expand tremendously.
• When air is pumped into the ball, it expands similarly to an inflatable. The football expands as a direct result of the considerable pressure exerted by the air inside it.
