Both hydrogen and helium are gaseous elements that are not as dense as the nitrogen and oxygen in air, and can be used to fill balloons to make them lighter-than-air. Helium is the least reactive of the two, and therefore safer to use.

Can you make a balloon that float in air?

Yes, a helium-filled balloon will float in the air because helium is less dense than the surrounding air. When filled with helium, the balloon experiences a buoyant force that causes it to rise and float.


If you wanted to make a balloon float in the air which gas should you use to fill the balloon?

Helium gas is lighter than air and hence balloons filled with helium will float in air.


What gas are balloons filled with to make them float?

Balloons are usually filled with helium gas to make them float. Helium is lighter than air and provides the necessary lift for the balloon to float.


Does a balloon filled with heleum depend on gravity?

I am not sure what you mean by 'depend' (please try and make your questions clear) but if you mean does the fact that a helium filled balloon will float (or rise) depend on gravity? Then the answer is Yes. if you were to take a helium filled balloon to the space station and release it inside, it would not rise, it would behave just the same as if you released a bunch of keys.


What is inside the inflated balloon?

Helium goes into a balloon to make it float.


Why does not a balloon full of oxygen float?

A balloon filled with oxygen, like any other gas, will only float if it is less dense than the surrounding air. The weight of the balloon, the gas inside, and the container itself typically make the balloon denser than the air, causing it to sink. A helium-filled balloon floats because helium is much lighter than air.


How does heating the air inside a hot-air balloon make it to float?

Heating the air inside a hot-air balloon decreases its density, causing it to become lighter than the surrounding cooler air. This buoyant force generated by the temperature difference causes the balloon to float upwards.


What gas makes balloon drop not float?

Helium is the gas commonly used to fill balloons to make them float. If a balloon is filled with a gas heavier than air, such as carbon dioxide or nitrogen, it will cause the balloon to drop instead of float.


Which gas is used to fill a hot air balloon?

A typical hot air balloon is filled with the same air we breath.


Why is an hot air balloon called a hot air balloon?

A hot air balloon is called such because it is filled with hot air to make it rise. When the air inside the balloon is heated, it becomes less dense than the surrounding cooler air, causing the balloon to float upwards.


What type of gas is used inside foil balloons?

Foil balloons are filled with helium. Helium is lighter than air and because of this, it is one of the gases that can make a balloon float. It's the preferred gas for these type of balloons because it isn't flammable and is inert, meaning undesired chemical reactions are rare.


What element is used inside balloons so they float?

Helium gas is most commonly used to fill balloons to make them float. Helium is lighter than air, which causes the balloon to rise and float.
