Carbon dioxide, also known by the chemical formula CO2, has a higher density than the other gases found in air, which makes CO2 heavier than air. Air is composed of approximately 78 percent nitrogen, 21 percent oxygen, and less than 1 percent of other gases.Density is defined as mass per unit volume of a substance, expressed in kilograms per ...

Liquid oxygen is actually heavier than liquid carbon dioxide by a little bit. 1.149 grams/ milliliter for liquid oxygen at its boiling point versus 1.101 grams/ milliliter for liquid carbon dioxide. If you cool even more and get solid oxygen and carbon dioxide you would find than carbon dioxide is slightly heavier than a similar volume of solid ...

"Like carbon dioxide, nitrogen dioxide is heavier than air so the highest concentration of gas is typically located at the silage surface, which is the area where a person will be going if they need to enter the silo for any reason." Out in the open atmosphere, there is enough motion in the air to keep the oxygen and carbon dioxide mixed up.

no, carbon dioxide is lighter than oxygen.As trees need carbon dioxide and animals need oxygen.Logic says carbon dioxide should be lighter than oxygen.Though Molecular weight of CO2 is more than oxygen but the surface area of carbon dioxide on its volume make it lighter than oxygen.

Oxygen as a gas is heavier than carbonmonoxide This is because carbon monoxide consists of one oxygen atom and one carbon atom. This says that if the mass of oxygen is x and the mass of carbon is ...

It's one of the givens of kinetic molecular theory. It explains why hydrogen gas diffuses faster than carbon dioxide. Thus there is a greater probability that a lighter molecule like hydrogen will be able to cross a given transient empty space faster than a heavier one before the gap, so to speak, closes up.

Air is a mixture of gases, mostly nitrogen and oxygen 78.1% nitrogen 20.9% oxygen 0.9% argon 0.1% other gases (like carbon dioxide) Air is well mixed, so we do not usually talk about oxygen being lighter or heavier than air. Helium, on the other hand, is much lighter than air (nitrogen and oxygen), so that is why a helium-filled balloon goes up.

That title is a question I get a lot during home inspections. And this one - Is carbon monoxide lighter or heavier than air? Of course, any time you have gas appliances or a wood-burning fireplace, you should have at least one carbon monoxide (CO) detector in the home.
