Question

how does air pressure help to inflate a football​

Answer 1

Explanation:

Use the air pump until the gauge on the pump shows the necessary BAR or P.S.I. For example, if your football should be at 0.5 - 0.7 BAR (7.2 - 10.1 P.S.I.), keep the pump on until the gauge is between those numbers. ... Do not over-inflate the ball by going over the recommended BAR or P.S.I....
