The gas molecules are constantly in motion, colliding with each other and the walls of the ball. The pressure inside the ball is also much greater than the pressure outside the ball. When there's a hole in the ball, the molecules keep colliding, and some make there way out through the hole. Remember that the molecules want to go to the area of lowest pressure so that they can be at equilibrium.

The inside of the ball becomes filled with the air you pump in, thus inflating the ball and turning it from a flat ball to a round one.
Yes, there is more mass in an inflated balloon than a deflated one. The difference is the gas that was used to inflate the balloon. The gas may not weigh very much, but it does make a difference.
Rubbing wool on the ball transfers electrons (negatively charged) from the wool to the ball. The excess charge builds up and produces static electricity.
It bounces off (is reflected) by the surface of the basketball. If some of the reflected light reaches your retina then you will see the ball.
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.
When air leaks out of an inflated ball, the gas particles inside the ball escape through the opening created by the leakage. This causes a decrease in pressure inside the ball, causing it to deflate as the gas particles move from an area of high pressure (inside the ball) to an area of lower pressure (outside the ball).
the gas comes out with pressure and the ball flattens.The gas so released mixes with the atmosphere to maintain balance or equilibrium

The gas particles are freely moving because they are not tightly arranged together

The type of air that keeps a beach ball inflated is kinetic energy.
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.
As air particles get colder, they lose kinetic energy and move more slowly. This causes the pressure inside the ball to decrease because there are fewer collisions between the particles and the walls of the ball.
Hockey
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. :)
