It can be, but usually not.
Helium is a bit expensive, and it'd cost too much for most balloonists to use it.
It's cheaper to use a hot air balloon.
helium is lighter than air. hence balloons filled will helium will float in air.
Helium is a gas used to inflate lighter than air balloons.
Hydrogen, until the Hindenburg,then everyone realized that "Hey, Hydrogen isn't that safe to use!"Hot air balloons, you mean?? Just air that is hot.Actual hand balloons and such? Helium or again, just air. Helium floats better because it is lighter than the surrounding air around it. Helium and air are still used in both.
Helium is used in blimps and balloons. It is the second lightest element to hydrogen, which is not used because it is highly flammable.
Hot air, hydrogen or helium are lighter than cold air.
If you want the balloons to float, you would probably use helium.
Helium is the most used gas for balloons; sometimes hot air and rarely hydrogen.
Helium is a gas used to inflate lighter than air balloons.

No, it is not. "Regular" air is used, and it is heated. Hot air is less dense than cooler air, and it will rise. If hot air is trapped in an envelope, it will give lift to the envelope and an attached payload.

Helium is typically used to fill airships and balloons due to its low density, which allows them to float in the air.
Gases used are: air (and hot air), helium.
