How do they seal the air inside a tennis ball?

A sealed pocket of Air is inside the hollow center of a table tennis ball.

There is air inside it. Not nothing.

The temperature of the ball does not affect the surrounding/outside air, but it does affect the air inside the ball.

A heated tennis ball bounces higher because the hot air inside the ball is lighter than the air around the ball therefore giving the tennis ball the ability to bounce higher.

its is the air inside the tennis ball that you should be concerned with. Cold air is compressed and gives the ball less bounce, hot air is less dense and pushes on the sides of the tennis ball from the inside. Another important factor is altitude. altitude changes the amount of oxygen in the air. this doesnt change rebound it causes the ball to travel further in air.

The tennis ball is distorted from its round shape when it hits the ground, which means the volume inside is reduced or the air inside is being compressed. The air then pushes back to restore the tennis ball's original shape and therefore bounces off the ground.

It doesn't. A tennis ball has a mass of about 57g A golf ball has a mass of about 46g The golf ball is DENSER because it has material inside it (usually rubber) but the tennis ball is full of a gas (air).

A golf ball is heavier than a table tennis ball because it has a Higher density, the golf ball has no space inside of it while the table tennis ball has a large pocket of air.

Because a golf ball is denser. When you cut a golf ball and a table tennis ball in half, the golf ball is solid all the way through. The table tennis ball has a cavity filled with mostly air inside.

the ball is the same as a tennis ball. it is made out of air on the inside so it will float in the air for a while and then will endventualuy fall.

It the ball has air in it, then an increase of temperature will increase the pressure within the ball, over the short term. Over the long term, all pressurized tennis balls lose pressure. If the ball is the pressureless type, it has no air to be affected by temperature.

Generally air is the gas in a tennis ball

The mass of the objects don't matter in free fall - they both fall at the same time, assuming air resistance is negligible. However in your case, the golf ball has less air resistance than a tennis ball (add that to the fact tennis ball consist most of air inside adding more to the air resistance). Therefore, the golf ball falls faster than a tennis ball - Hope that helped!

Tennis balls have pressured air inside of them from the manufacturer. This air on days with higher temperatures will increase and expand this internalized pressure of the ball, thus making the ball more solid and hard. This increases the "bounce" of the ball

The heat will cause the air inside the table-tennis ball (ping pong ball) to expand and so push the dint out.

As the air temperature in the tennis ball raises, so does the pressure inside. As the pressure increases, the ball becomes harder and acts like one of those solid rubber super bouncy balls.

No, a room temperature ball does not bounce higher than a heated tennis ball. In fact, the heated tennis ball will bounce higher than its room temperature counterpart. This is because tennis balls rely on a high pressure internal pocket of air for their bounce. Heating the tennis ball would increase the pressure of the air inside the ball (pressure varies as temperature) which would cause the tennis ball to bounce higher. This holds (albeit…

Table tennis balls are made of a type of plastic called celluloid. The odor in the ball is a by-product once the ball becomes cracked and the inside is exposed to air.

will a basketball or a tennis ball bounce higher with more air?

I believe the tennis ball would bounce the highest if you were to put equal force on each ball and throw it to the ground. I don't know exactly why, but I tested this once, and it seems the tennis ball bounces the highest because of the fact that it has the most air pressure inside of it.

Tennis balls have pressured air inside of them from the manufacturer. This air on days with higher temperatures will increase and expand this internalized pressure of the ball, thus making the ball more solid and hard. This increases the "bounce" of the ball. Vice versa for cold temperatures, the pressure will instead contract and have less pressure inside making it softer.

Tennis balls are made of a layer of rubber surrounding a hollow center. Then they put a thin layer of adhesive on the rubber and cover it with a layer of felt (traditionally yellow). The air pressure inside the ball is 12 psi (pounds per square inch) greater than ambient air pressure at sea level (the ’normal’ air pressure all around you). The ambient air pressure is 14.7 psi, so all together, the pressure inside…

The air inside the ball expands on heating and this, in turn, makes the ball harder / more elastic.

The heat cause the air inside the ball to expand and undent the ball

The canister is actually pressurized to balance the pressure inside the container with the pressure inside the tennis balls. This will prevent the balls from going flat. The pressure inside the balls is 12 psi over the normal air pressure (for comparison, the pressure in a car tire might be something like 32 psi). The rubber shell of a tennis ball isn't enough by itself to keep the ball bouncing high, so the pressurized air…
