What else can I help you with?
Why do they use helium gas in blimps?
Helium has a low density and causes balloons and blimps to float
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.
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.
Can gas be used to levitate an object?
Yes, this is the basic principle of blimps and balloons.
What gas law explains the replacement of hydrogen to helium in blimps?
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.
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.
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.
What gas law is used in flying blimps?
Boyle's Law is used in flying blimps, as it describes the inverse relationship between the pressure and volume of a gas at constant temperature. By controlling the pressure of the gas inside the blimp, pilots can adjust the volume and thus control the buoyancy of the blimp.
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.
Can blimps go to the moon?
No. Blimps require atmosphere.
