Helium is less dense than nitrogen and oxygen, the main components or air. Any given volume of helium has less mass than the same volume of air at the same pressure. Balloons filled with helium therefor rise through air just as air bubbles rise up through denser, heavier water.
A helium filled ballon expands as it rises displacing an increasing volume of air as it goes. This is because the air around it becomes thinner and less dense with altitude. Air pressure at sea level is 1 atmosphere or about fourteen and a half pounds per square inch dropping to zero at the edge of space.
Hydrogen is less dense than helium and therefor has a greater lifting capacity per unit volume than helium. Both were used for airships but helium was much safer because it's not flammable like hydrogen.
The altitude of airships was controlled by venting (releasing) excess gas to stop them rising too far or too fast. They also carried lots of water ballast. It would be dumped as needed to stop the airship from descending too fast. Airships and submarines use similar methods to fix their vertical positions. Whether it's in liquid or gas, it's all about density, pressure, and gravity.

What else can I help you with?
What do you blow up a balloon to make it fly?
Helium gas is typically used to fill balloons to make them float or fly. Helium is lighter than air, so it causes the balloon to rise due to the difference in density between the helium gas inside the balloon and the surrounding air.
Can you make a balloon fly without hot air or helium?
Yes, you can make a balloon fly using propellers or an electric motor to provide thrust. By attaching a propeller or motor to the balloon, you can create lift and propulsion to make it fly without the need for hot air or helium.
Can balloons blown up by mouth fly?
Balloons blown up by mouth can fly briefly due to the air pressure inside causing them to float for a short period of time. However, they will eventually lose air and fall back down. helium-filled balloons are typically used to make them float for longer periods.
Which gas is use to fly balloons?
Helium gas is commonly used to fly balloons due to its lighter-than-air properties. It is non-flammable and safe for use in balloons to provide the lift needed for them to float in the air.
What gas does make a balloon float?
Helium gas is commonly used to make balloons float. Helium is lighter than air, so filling a balloon with helium makes it buoyant and able to float.
What do you put in a balloon to make it fly?
Helium
What those helium do to make things fly?
Helium is lighter than air, hence it will rise up in air, making things fly.
How are balloons and airplanes alike?
They both fly. The only difference is that a ballon has helium to make it fly but air planes use gas to make it fly.
What do you blow up a balloon to make it fly?
Helium gas is typically used to fill balloons to make them float or fly. Helium is lighter than air, so it causes the balloon to rise due to the difference in density between the helium gas inside the balloon and the surrounding air.

Does helium help the balloon fly?
Yes, helium will help a balloon fly. Helium does not affect the direction that a balloon goes, but it will keep it in the air for quite some time.
How do balloon fly?
Balloons are filled with helium. Helium is a gas that can make light objects float, or make your voice all squeaky. So if you want to pee your pants laughing, go cut a small hole in a balloon and suck the helium out and then speak.
Which balloon would fly higher the one with helium or the one with air?
The balloon with helium.
What makes a helium balloon fly?
A balloon filled with helium flies because helium weighs less than air.
Why do balloons fly with helium and not with normal human oxygen?
because helium is lighter than air,therefore, when letting go of the balloon it will fly up
How many balloons do you need to make a chihuahua fly?
258 helium filled balloons filled to 34 psi each
Will you fly if you inhale helium?
more importantly are you thick, it doesnt, helium diffuses through us
