What chemicals do balloons contain?
helium or oxygen depending on what you put in them
How dense is helium compared with air?
Which is more dense: water or helium? - Water is more dense, because water does not float like helium does. It is below air. That's why we have oceans and lakes and rivers.
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.
Helium hydrogen and air are in this state of matter?
Helium, hydrogen, and air are gases.
What objects contain helium?
Helium is generally used in helium balloons and blimps. Helium is lighter than air and these items will float in air
What chemicals do balloons contain?

What is more dense helium gas or air?
air is more dense than helium
Is there more helium or hydrogen in a hot air balloon?
A hot air balloon doesn't contain helium or hydrogen.

What has more density air or helium?
The density of helium is less than the density of air. You can infer this without doing any calculations by thinking about the classic example of inhaling the helium from a balloon and talking. Your voice gets squeeky high because helium is less dense than air - that is, your sound waves propagate faster through helium than through air, therefore helium is less dense.

What has more lift hot air or helium?
Helium has more lift because its just like in a helium balloon.it stays on the roof because it wants to go higher. and hot air doesnt stay with the wind blowing it.
How is energy changed from one type to another?
air is oxygen. the atmosphere is a verityof chemicals: co2, oxygen, helium etc etc
Which air keeps a balloon filled more helium air or regular air?
Helium balloons "deflate" more quickly than balloons filled with air. This is due to the low mass of the helium atom that at the same temperature travels much more quickly than oxygen or nitrogen molecules and hence goes through the balloon membrane more readily.
Why is exhaled air more dense than helium?
Helium is a relatively light gas which is lighter than air at ground level. Exhaled air contains a lot of water vapour and carbon dioxide relative to normal air. Since ground level air is less dense than helium, adding water vapour and carbon dioxide makes exhaled air even more heavier than helium.
Why does helium rise and regular air sink?
A balloon filled with helium floats and a balloon filled with regular air falls to the ground because helium has less density than air so the air causes the balloon to sink because there are more molecules in it. The helium has less molecules in it so the balloon rises.
Would helium weigh less than a bottle with no air?
Yes, because the helium is buoyant relative to the atmosphere at ground level. However, the helium would have more mass than the bottle with no air.
