Are most gases lighter or heavier than air?
No, many are lighter. Perhaps the most common lighter-than-air gas is helium, which is used to fill party balloons.
fluids are heavier than gases. When hydrogen its by itself is lighter than water as so the oxygen is also lighter. Once combined they form a fluid thus the combination of two gases produced a fluid which will turn heavier.
Well, when I made a vortex using air, I used gases that are lighter.
No, all gases are lighter than solids
because of the chemicals inside it. Edit: This answer is incorrect. Smaller, lighter weight gases diffuse faster than larger, heavier gases.
The idea is that they tend to be made up of lighter molecules; on average, these move faster (for a given temperature) than heavier (actually, more massive) molecules.
The process of mixing of two or more gases to form a homogeneous mixture is called Diffusion. Lighter gases diffuse faster than heavier gases
They can take the shape of their container, and some are able to rise above air (some gases are lighter and some are heavier than room air.)
Greenhouse gases are obviously lighter than air How then are they measured by weight How does one weigh something that is lighter than air?
Greenhouse gasses are NOT "obviously lighter than air"; carbon dioxide is significantly heavier than air. One way to weigh something that's lighter than air is to weigh it in a vacuum.
Helium exists as a monatomic gas, with atomic mass of 4.0. Thus any gas with a molecular mass higher than 4.0 would be heavier than helium. Hydrogen is the only gas that is lighter than helium; all others are heavier than helium.
Coal can be heavier or lighter than water depending on its type. Most types of coal are heavier than water in terms of density, however, broken bituminous coal has only a density of 0.833 kg/m3, so it is lighter than water.
Helium is a gas, so it is not lighter than gas. It is like asking why is water heavier than liquid. Helium is less dense than all other gases except hydrogen, because it has an atomic weight of 4.
It sinks as it's heavier than Oxygen. There are only 3 elements that are gases at ordinary temperatures that are lighter than Oxygen: Hydrogen, Nitrogen and Helium.
It is lighter than air.
it is lighter than water.
Oxygen is the heavier part, nitrogen and argon are lighter, even water vapor is lighter.
Just, simply, Lighter than Air Vehicles are lighter than air, so that makes them fly, and Heavier than air vehicles are heavier than air, but they use airfoils on the wings to fly.
Methane is lighter than air.
One is lighter and the other one is heavier. :D
"Lighter than air" aircraft are lighter than air! The most common are blimps. They do not rely on wings to generate lift. They contain a lighter than air gas (ex:helium) that lifts the craft into the air when ties to the ground are released. "Heavier than air" aircraft are the opposite. They rely on wings to generate lift to get into the air. Common heavier than air aircraft are general airplanes you see in the… Read More

Helium is lighter than air
Sulfur hexafluoride is the heaviest of the heavier than air gases. http://en.wikipedia.org/wiki/Sulfur_hexafluoride
That's not QUITE what it does, or at least it's not ALL of what it does. For similar compounds, in general, lighter molecules boil - that is, become a gas - at a lower temperature than heavier ones. "Cracking" is the process of splitting large, heavy molecules into smaller, lighter ones. Because they are lighter, they boil at a lower temperature, and so will become gases when the heavier starting material would still be a… Read More
No. The atmosphere is roughly 80% N2, 20% O2, and about 1% of other trace gases. The molecular mass of N2 is about 28, the molecular mass of O2 is about 32. So, no O2 is not lighter than air, it is slightly heavier.
meson is heavier than electron but lighter than proton
Aluminum is actually lighter than titanium
It depends on the specific compound, though most are denser than air.
They are 2.7 times heavier.
Light gases; Gases that are light weight will more easily reach escape velocity than heavier gases.
Most refrigerants are heavier than air. Because of this, they can displace air and cause someone to suffocate.
Carbon Dioxide is heavier than the air.
Nitrous Oxide is heavier than air.
they're lighter than air
Xenon is more than 4.5 times heavier than air.
Some are heavier, but some are lighter. For example, methane rises but propane sinks.
No, heavier gas particles diffuse slower than lighter gas particles
No. Chlorine gas is not lighter than air. It is heavier than air.
The answer depends on whether the solute is heavier or lighter than the solvent.
It depends on 8500 what! 4 tons is lighter than 8500 tons, 4 tons is heavier than 8500 micrograms, 4 tons is neither heavier nor lighter than 8500 centimetres.
Natural gas is lighter than air and rises.
"Gas" could mean anything - there are many different types of gases. Some are lighter than air (composite of mostly nitrogen and oxygen) like methane or helium and some are heavier like argon or carbon dioxide.
heavier No, although the most of air is nitrogen, pure N2 (28.0 g/mol) is lighter because the other 19% O2 (32.0 g/mol) is heavier. The 1% Ar (18 g/mol) alone cannot compensate that.
The lighter elements have less protons and neutrons than heavier ones. It really is as simple as that
There are two problems with this question, one is that inert gas is more than one substance and the second is that so is air. Air is a mixture of nitrogen, oxygen, carbon dioxide, argon and other gases. The best way to determine its mass is to take an average between these components. Next, what's an inert gas? Strictly speaking, the inert gases are the noble gases, which are the elements in group 0 of… Read More
It depends on which oil you mean. Some oils are heavier than water, some are lighter. Most of things that the average person thinks of when they hear "oil", such as motor oil or vegetable oil, are lighter than water. Other oils are heavier. There are a huge number of things that are all considered 'oils', so the question needs to be more specific.
Gases are lighter than solids and liquids, so light that they can be in our atmosphere. Example, when water evaporates it is light and goes up into our atmosphere where it will condense to form liquid, which is now heavier and more dense and therefore falls
Gasoline is a mixture of various hydrocarbons, most of which produce vapors that are denser than air.
Relatively, no. Gas is lighter than its liquid form, and most times the solid form is heavier than its liquid form.
