Does air pressure affect the distance a football travels?
This soccer science fair project serves to acquaint students with basic information on how the amount of air in a soccer ball can affect the distance it travels when kicked with a consistent force. The greater the air pressure in the ball, the farther it will travel when a force is applied.
What happens when you fill a football with helium?
A helium-filled football will fly higher and farther than one filled with plain old air. She had friends in the chemistry department vacuum the air out of four footballs and fill two with helium, a gas lighter than air, and two with argon, a gas heavier than air.
How does the air pressure affect a soccer ball when kicked?
The pressure in the atmosphere will also affect how far the ball when kicked. The lower the pressure then the less friction there is for the ball to travel. -Air pressure determines the ball’s level of stiffness. Higher air pressure creates more energy, and allows the ball to keep its shape when it is kicked.
Does helium affect a soccer ball?
So filling a small ball with helium would have a negligible effect on its behaviour. Trying to make a soccer ball float by inflating it with helium would likewise fail. If the ball is normally inflated to above atmospheric pressure, the buoyancy effect of replacing the air with helium would be increased.
Does helium make a football go further?
Helium-filled footballs will not travel further or hang in the air longer than the heavier air-filled footballs.
Will an air mattress float if you fill it with helium?
No. Helium at same air pressure and temperature as the air around it can only lift about 66 pounds per thousand cubic feet.
What happens if you fill an air mattress with water?
The plastic will expand and then in a few hours (or over night) you fill it again. Even an air mattress can suck the heat out of you if it gets cool out since you don’t have the full matress to protect you. I think it would hold the water, but you will never get it all out which will result in mold.
Can an air mattress explode?
The mattress may ignite or explode. Keep the airbed away from stairs, windows and sharp, breakable objects. Never stand, walk or jump on your airbed.
Can helium make things lighter?
So why are helium and hydrogen so much lighter than air? It’s because the hydrogen and helium atoms are lighter than a nitrogen atom. They have fewer electrons, protons and neutrons than nitrogen atoms do, and that makes them lighter (the approximate atomic weight of hydrogen is 1, helium is 4 and nitrogen is 14).
Are helium tanks lighter when full?
Short answer: it would weigh more when full if it’s a pressurized tank. This is because density increases with pressure. Helium, at room temperature and atmospheric pressure, is much less dense than air. This causes things (like balloons) containing helium to appear to decrease in weight, due to buoyancy.
What is the world’s lightest metal?
metal microlattice
Is there a gas that is lighter than helium?
As other answers have noted, the only gas lighter than helium is hydrogen, which has some flammability issues that make it more difficult to handle safely than helium. Also, in practice, hydrogen is not significantly “lighter” than helium.
Whats heavier hydrogen or helium?
Hydrogen versus helium Although helium is twice as heavy as (diatomic) hydrogen, they are both significantly lighter than air, making this difference negligible. The lifting power in air of hydrogen and helium can be calculated using the theory of buoyancy as follows: Thus helium is almost twice as dense as hydrogen.
Which is safer hydrogen or helium?
Because helium is lighter than air and hydrogen is another gas lighter than air. Hydrogen is highly inflammable and incredibly dangerous. Helium atoms are bigger and diffuse less rapidly through a balloon and it won’t burn or react in anyway.
