to check if a Basketball or any ball is inflated properly, the referee must bounce the ball on the floor to see if it comes back up to a appropriate height for the players. :)
No foreign substance is allowed on the ball. The referee certifies the ball for game play. As a referee I would require the ball to be cleaned of mold or I would not allow it for game play.
Air pressure is the property that keeps a beach ball inflated. The air molecules inside the beach ball exert pressure on the walls of the ball, keeping it inflated.
An NFL size football is inflated to 7-9 lbs that's all i know. Update: Actually, a correctly inflated ball is filled with air to a pressure of 12.5-13.5 psi.

If it is a solid rubber ball it is not inflated. A hollow ball can be inflated. The more pressure inside, the "harder" the ball will be and the higher it will bounce. To much pressure and you risk rupturing the "rubber" bladder.
When air leaks out of an inflated ball, gas particles within the ball escape through the opening. The pressure inside the ball decreases as more gas particles leave, causing the ball to gradually deflate.
Hockey
A trick to taking out the wrinkles from a soccer ball that has not been inflated for a while is to let some air out of the ball. Then, air the ball up again while heating the ball with a hair dryer.
I can give you several sentences.He is going to referee the ball game.The referee blew his whistle for half time.They fought for half an hour with no referee.
The referee's whistle.
A fully inflated ball bounces higher because it has more air pressure inside, providing more energy for the bounce. The higher air pressure helps the ball to retain its shape better during impact with the ground, resulting in a more efficient transfer of energy.
The ball is the responsibility of the referee.
