The helium balloon rises in air because the density of helium inside the balloon is less than that of the surrounded air that is displaced by the balloons volume. So the balloon is lighter than the surrounding air. Ice cubes float in a glass of liquid water for the same reason.

What is the difference between a helium balloon and a hot air balloon?
A helium balloon does not need energy to rise in the air. A hot air balloon needs fuel to rise in air. That is it needs heat energy to rise in air.i love Pizza squares i hope they put helium in then one dayHelium relies on the fact that helium is lighter than air. Hot air balloons rely on the fact that hot air has less volume than cold air and is lighter than the air around it. hot air balloons use hot air to cause the balloon to lift as helium balloons use a special gas to cause lift
Why do helium and hot air balloon's rise?
Because helium is less dense than air, so it rises. Hot air balloons rise because heated air from the burner becomes less dense and therefore rises.
How do helium balloons work?
helium balloons get filled with a amount of air in which is called helium it is used to make balloons float around in air. helium is a inert,gaseous element!!!!!yea i kenisha am smartHelium is less dense than air, therefore a helium-filled balloon will float in air.Helium is lighter that air, so it effectively floats on air. As a helium balloon is submerged in air, it rises upwards (like an air filled bubble in water).
What last longer helium fill balloon or hot air balloons?
hot air balloons
What makes balloons float when they are full of air but not float when they are deflated?
When balloons float they have helium in it. Helium is not air, but a gas. It's lighter than air, which makes it float.
Does helium rise?
yes honey, that's why hot air balloons rise
What is helium mostly found in?
In helium balloons and blimps. Helium is lighter than air. So balloons or blimps filled with helium will float or rise up
Will warming helium balloons make them float?
Helium is lighter than air. so balloons filled with helium will float in air. warming will make them float or rise up faster.
What happen when a balloon is filled with helium?
Helium is lighter than air and a balloon filled with helium may rise up.
Why do big balloons with helium gas floats and buoyed up?
Helium is lighter than air, hence balloons filled with helium will float and rise up.
Can you inflate a balloon without helium?
You can use air instead of helium, but it will not rise. The reason helium balloons rise is because helium is lighter than air. I am sure other gases can be used also.
How does helium help balloons?
Helium is lighter than air, hence it will rise up in air, making things float up in the air.
How do air balloons lift off from the ground?
Balloons filled with Helium rise because Helium is less dense than normal air. Hot air balloons lift off the ground because heat rises, and when the balloon is full of air of a higher temperature than its surroundings, the balloon will rise.
How high do hot air balloons go up?
they contain helium molecules which are lighter than the air we breath making the balloons rise
How does helium help flight?
Helium is lighter than air. So balloons or blimps filled with helium will rise up and float.

Why is helium better for balloons or lifting instruments?
Helium is lighter than air, hence it will rise up in air, making things fly.
