What else can I help you with?
What are helium's practical uses?
Helium is lighter than air. So balloons or air ships filled with helium will float.
What gas is used in balloons and air ships?
Helium
Which gas can be used in air ships and weather balloons?
helium
Is helium only used in balloons and air ships?
Helium is the most used gas for balloons; sometimes hot air and rarely hydrogen.
is helium used in air balloons?
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.
Is there helium on ships?
no
Why is it better to use hot air than helium?
Helium is very dangerous. It can easily ignite in the time of fire. So hot air is more preferable than Helium. ----------------- Helium is very safe to use as it is non-flammable, however, it is far more expensive than hot air.
What makes helium great to use in balloons and blimps?
Helium's density is less than the density of air, so it floats in air.
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.
Why do you use helium in balloons?
Helium is less dense than air, and therefore the balloon will float.
What air do blimps use?
Blimps use lighter than air gasses namely hydrogen or helium.
What gas was used to fill the first air ships?
Hydrogen was first used but was generally replaced with helium because of it's flammability.
