What makes a balloon float?
All balloons do not float. Those that do are filled with a gas that is less dense than the surrounding air, so that is is displaced upward by weight of the denser air. Small balloons are typically filled with helium, a much lighter gas than the nitrogen and oxygen in the atmosphere. Larger balloons may be filled with heated air, which occupies a greater volume and is therefore "lighter" than air outside the balloon. Some dirigibles (airships) were filled with the lighter but flammable gas hydrogen. Hydrogen can be split from water and used to fill thin plastic bags, which will also rise into the air like balloons.
What is the different between hot air balloons and hydrogen gas balloons?
Hot air balloons are filled with heated air, which expands and has less density than the surrounding air, so that the ballon floats upward -- until it cools back down. Hot air balloons usually carry a stove, to keep heating the air (which rises into the balloon, displacing the cooler air and pushing it out of the ballon -- this is an example of convection). Hydrogen balloons are filled with hydrogen gas, which is much less dense than air, so that it rises -- unless the hydrogen leaks out. Hydrogen is not only difficult to keep from leaking out, but also quite flammable and can explode if there is a spark nearby. Also: Helium balloons work similarly to hydrogen balloons, except that helium is not flammable, it is slightly denser than hydrogen, and it is rare and hard to find on Earth. The sun is composed primarily of hydrogen and helium, and the fusion process that makes it radiate comes from transforming hydrogen into helium, with a large release of energy.
Why don't air balloons use hydrogen gas?
Because hydrogen is EXTREMELY flammable and can burn from a wide range of air concentrations. It is more flammable than gasoline.
Is argon denser or less dense than nitrogen?
Nitrogen is four fifths of the air so their densities are very similar. Pure nitrogen is slightly less dense than air.
What gas makes balloon drop not float?
Any gas with a density higher than air. Carbon dioxide will do it, krypton is denser still, and will make it drop quicker. There are others too.
Why a balloon filled with hydrogen gas floats in air?
bcoz hydrogen gas is less denser than air and is exerts buoyant force on balloon
Is hydrogen denser than air?
No. Hydrogen gas (H2) is much less dense than air (that is why it was once used for flying zeppelin aircraft to keep them aloft).
Is natural gas denser then air?
No, Natural gas is lighter than air.
What is colorless gas that is denser than air?
Argon :)
Is fluorine denser than water?
No. Fluorine is a gas at room temperature a little bit denser than air.
What gas is denser carbon dioxide or hydrogen?
Carbon dioxide is denser.
How much heavier than air is chlorine gas?
Chlorine is about 2.7 times denser than air.
Is bromine gas denser or less dense than air?
yes
What commercially available inert gas or gases are heavier than air?
Argon, krypton, xenon, radon are denser than air.
A basic gas lighter than air?
Hydrogen and Helium are both lighter than air.
Is land denser than air?
There are 5 states of matter.1. solid2. liquid3. gas4. plasma (ionized gas)5. Bose-Einstein condensateAir is a gas and land is a combination of solids (rock, soil, etc) and liquid (water).Solids and liquids are denser than gases. So, yes, land is denser than air.
Does hydrogen gas rise in air?
Yes. Hydrogen is a gas, and all gases tend to diffuse. Whether or not air is present is irrelevant.
