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
Why do air ships use helium?
Because of its light weight
Is helium only used in balloons and air ships?
Helium is the most used gas for balloons; sometimes hot air and rarely hydrogen.
Why do helium balloon's float in air?
Helium balloons float in air because helium is less dense than the surrounding air. When a helium-filled balloon is released, the buoyant force acting on it, which is greater than the weight of the balloon, causes it to rise. This principle is similar to how ships float on water; the upward buoyant force allows the lighter helium to ascend through the heavier air.
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.
The early dirigibles air ships such as the Hindenberg were filled with hydrogen but this was later changed to helium Why were they originally filled with hydrogen and why was the change made?
Hydrogen was a highly flammable gas but as they became aware of it they filled the dirigibles with helium instead, which is a non-flammable gas.
What chemical property of helium makes it a better choice than hydrogen for use in airships?
It's very light (only hydrogen gas is less dense than helium), it's relatively cheap, and (most importantly) it's not flammable (hydrogen gas is--the Hindenburg was filled with hydrogen gas).
What is the abbreviation for helium?
He - Helium
What is the simble for helium?
The symbol of Helium is He. Helium's atomic number is 2.
Is the difference between helium in a jar in helium?
helium in a jar diff from helium atom
