Why is density of hydrogen lower than air and can be used to fill balloons why is helium used instead oh hydogen?
Because helium is lighter
What else can I help you with?
The density of hydrogen is lower than air and can be used to fill balloonswhy is helium used instead of hydrogen?
Helium is used instead of hydrogen in balloons because it is non-flammable, while hydrogen is highly flammable. This makes helium a safer option for filling balloons to prevent any potential fire hazards. Additionally, helium is also lighter than air, allowing balloons to float easily.
Helium is used in balloons instead of hydrogen because it is?
Helium is used in balloons instead of hydrogen because it is non-flammable. Hydrogen is flammable and can be dangerous, while helium is inert and poses less of a fire risk. Additionally, helium is less dense than air, providing better lift for balloons.
Why are helium used instead of hydrogen for balloons?
Helium is used instead of hydrogen for balloons because it is non-flammable, whereas hydrogen is highly flammable. This reduces the safety risk associated with using hydrogen in balloons. Additionally, helium is more abundant in nature and does not react with other substances, making it a safer and more practical choice for filling balloons.
Which other gas instead of hydrogen can be used for air balloons?
Helium - it's less reactive.
Why is Helium gas used in gas balloons instead of hydrogen gas?
Hydrogen is highly flammable and can easily explode. Helium is a more stable gas.
What did the macys Thanksgiving parade have instead of balloons?
the Macy's thanksgiving parade had floats instead of balloons
What other element besides water has a low density?
1) Water is not an element, a water molecule is made of three atoms of two elements. 2) Water has a density of 1 (1Kg/L). From that you should be able to work out average densities, although it depends on what you call a 'low density'. Oil, for example, is lighter (less dense) than water, although compared to H2, oil is fairly heavy.
Can a hot air balloon's heat source be powered by hydrogen instead of propane?
No, hydrogen burns much too precipitously. The emphasis is always, first and foremost, on safety, and properly handled propane has been found to be the best and safest fuel for hot air ballooning, all possibilities being considered.
Why do balloons fall instead of float?
Balloons fall instead of float when they are either not filled with a lighter-than-air gas, like helium or hydrogen, or when they are filled with a denser gas, like air. Additionally, if a balloon has a hole or is damaged, the gas inside can escape, causing it to lose buoyancy and fall. Furthermore, the weight of the balloon material itself can also contribute to its inability to float.
Why is hydrogen no longer used in air balloons?
For small balloons like individuals often have for recreational use, hot air is much easier to control than either hydrogen or helium.For the occasional blimp, or long distance balloon trip, Helium, while somewhat heavier than Hydrogen, has proven to be far safer.The Hindenburg has proven the inherent dangers of using Hydrogen Gas in blimps. While, in theory, pure hydrogen is not explosive without the presence of oxygen, any rupture in the thin material separating hydrogen from the air atmosphere can prove to be deadly.
Why is helium used to fill balloons instead of oxygen or hydrogen?
Helium will not burn. Hydrogen burns in air to form H2O (water) Thus in circumstances where a lite gas is required (e.g. in a balloon) it is safer to use Helium. see http://www.unmuseum.org/hindenburg.htm
Why a balloon is filled with helium gas instead of air?
So that the balloons float
