Filling a balloon with enough helium for flight takes a lot of helium, hot air balloons only use hot air because it only takes a couple of tanks of propane to heat the air, which is much more cost effective than filling the balloon with helium.
Airships use helium because they are used to stay in the air for extended periods of time, so it makes sense to pay for the helium to fill it once, rather than the propane to keep the air hot.
Yes, balloons filled with helium will be buoyant in air
Balloons are not called helium; they can be filled with helium because this gas is not flammable and has a very low density.
Helium itself is not flammable. However, the material used to make the balloon, such as latex or mylar, can be flammable. It is important to avoid exposing helium-filled balloons to open flames or high heat sources.
Helium is a gas used to inflate lighter than air balloons.
Helium is lighter than air, so balloons filled with helium will float. It is also non-flammable and safe to use. Additionally, helium does not react with other chemicals, making it a popular choice for filling balloons.
You can get helium balloons filled at party supply stores, grocery stores, or stores that specialize in balloons and party decorations.

Balloons are not called helium; they can be filled with helium because this gas is not flammable and has a very low density.
bcoz helium is lighter than air
Balloons are not called helium; they can be filled with helium because this gas is not flammable and has a very low density.
In helium balloons and blimps. Helium is lighter than air. So balloons or blimps filled with helium will float or rise up
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.
Helium.
Those balloons are filled with helium gas. Helium is lighter than air. Helium is a noble gas.
258 helium filled balloons filled to 34 psi each
Helium is lighter than air, so a balloon filled with helium will float. In contrast, air-filled balloons will sink because the density of air is greater than that of helium. Additionally, helium balloons will deflate faster than air-filled balloons due to its smaller molecular size.
