The replacement of hydrogen in blimps with helium is not based on the gas laws but rather on the fact that hydrogen is highly flammable whereas helium is entirely non flammable.
In fact based on the gas laws hydrogen would actually be better for blimps because its has lower molecular mass and is therefore less dense than helium.
What else can I help you with?
What air do blimps use?
Blimps use lighter than air gasses namely hydrogen or helium.
What gas is used in blimps today and why?
To my knowledge helium is the only practical lift element for blimps. Hydrogen actually works better than helium, and it is cheaper, but it is highly combustible and not used anymore.
Both hydrogen gas and helium gas are lighter than air. Why is helium used to lift blimps instead of hydrogen?
Helium is non-flammable, making it safer than hydrogen which is highly flammable. This reduces the risk of fire accidents when using helium to lift blimps. Additionally, helium is more abundant and easy to obtain compared to hydrogen, making it a more practical choice for lifting gas.
How do blimps fly?
They are filled with helium gas. They used to be filled with hydrogen gas but that proved to be deadly at times.
A flammable gas once used to fill blimps?
The flammable gas once used to fill blimps is hydrogen. Despite its higher flammability compared to other gases, hydrogen was used due to its lightness and abundance. However, hydrogen's flammability posed a risk of explosions, leading to the decline in its use for blimps.
Why do they use helium gas in blimps?
Helium has a low density and causes balloons and blimps to float
What are two differences between the good blimps of today and the airships Hindenburg?
Today's blimps are not filled with flammable hydrogen gas like Hindenburg was, but normally the non-flammable helium.
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
Why is helium a better choice from the gas of choice for blimps?
Most early blimps were filled with Hydrogen, which is exretemly flammable and prone to ignite due to atmospheric changes. (Remember the Hindenburg??) Helium is a "noble gas" and therefore less susceptible to atmospheric changes.
Has helium ever been used in blimps?
Yes, helium has been used in blimps as a lifting gas. Helium is less dense than air, which allows it to provide buoyancy and help the blimps stay afloat. However, today, most blimps use a combination of helium for lift and air for control and propulsion.
Do they still use helium in blimps?
Yes, helium is still commonly used in blimps due to its low density and non-flammable properties, making it a safe option for lifting aircraft. Helium provides the necessary buoyancy to keep blimps afloat and is widely used in the aerospace industry for this purpose.
Why isn't hydrogen used in blimps?
In 1931, a large passenger dirigible lifted with hydrogen burst into flames while landing in Lakehurst, NJ. Since then, hydrogen has been considered too dangerous to use in airships under normal conditions.because hydrogen is a very flammable gas and can catch fire easily on an airship.an example of this is the Hindenburg in 1937
