Is air a gas or a solution?

hey! Air is a mixture of gases thus it is solution, it contains Nitrogen-78%, oxygen-20.9% carbon dioxide0.003% and some rare gases

An idea would be, "Which gas could you fill a volleyball up with that would make it go better?" They you can have regular air, carbon dioxide, and helium. Then you make a hypothesis based on what you know, try one of them, and see if you were wrong.

I don't like the term "easily", because that's vague. Gases can be compressed, as people have noted, because the space between gas molecules is large but unoccupied. However, you do have to perform work in order to compress a gas (thereby using energy).

I thought it was the gas it gives out

air-it is all about the air

To be precise, the answer is no. Do u noe why? The mean mol wt of air is 29 whereas that of CO is 28.\n\nlet me show u how i get these answers:\nC=12,O=16,mol wt of O2=32g/gmol,mol wt of N2=28g/gmol\nmol wt of CO = 12+16\n             =28\nas for air, by common sense, we know that air is made up of O2,N2, and other gases,rite? As the mol composition of other gases are very negligible(<1%), we assume air is only made up of O2 and N2. Air consists of 21mol% O2 and 79mol% N2.\n\nlet's take a basis of 100gmol(or 100mol)\nmoles of O2=21gmol\nmoles of N2=79gmol\nmass of O2=21X 32g/gmol\n          =672g\nmass of N2=79X28g/gmol\n          =2212g\ntotal mass= 2212+672\n          = 2884g\naverage mol wt of air=total mass/total moles\n                     =2884g/100gmol\n                     =28.84g/gmol\n                     =29g/gmol(whole no.)\n\nsince the ave mol wt of air is greater than that of CO, so aCO is not heavier than air,instead,slightly lighter than air.\n\nDoes it answer ur question?

As the temperature of a liquid increases, the less gas it can hold dissolved. If you set a cold glass of water on the counter, it contains dissolved air. That is what th fish breath, dissolved air. As it warms less air can stay dissolved, so it comes out of solution on the side of the glass.\n\nIt is not the H or O from H2O

not sure, i think its some kind of gas?

Solids, liquids, and gases refer to the individual properties of matter.  Air pollution is a mix of liquids solids and gases depending on what the pollution is.  Smoke for instance is just micro-solid particles in the air.  Hydrogen sulfide for example would be a gas.

We don't breathe oxygen...we breathe a mixture of mostly nitrogen.\n\nThe air we breathe is made up of significant quantities of four gases:\n\n   1. Nitrogen (78%)\n   2. Oxygen (21%)\n   3. Argon (0.94%)\n   4. Carbon dioxide (0.04%) \n\nWhen we breathe in air, our bodies consume its oxygen and convert it to carbon dioxide. Exhaled air contains about 4.5-percent carbon dioxide. Our bodies do not do anything with nitrogen or argon.

The most likely explanation is Methane Gas

A real gas is a form of matter that will conform to the sides of its container.  As it is compressed its temperature increases.  It is the only form of matter than can be compressed at all.  Gas is the least organized form of matter.

even if the air isnt polluted, there is still carbon dioxide and water vapor in the air.  When carbon dioxide(CO2) and water(H2O) react in air, they form Carbonic Acid (H2CO3).  Since it is an acid, it is acidic

Yes gasses in the air (oxygen, nitrogen, CO2, etc.) dissolve in the water (hence the fish and algae breath). Also many pollutants also dissolve in water (much easier than the gasses). If they are present in the air they will dissolve in the water, either by transfer (just the pollutants, not the gasses) or with the gasses.

Could be Liquid Gas. Need more info.

Air is is mainly nitrogen  and oxygen with a mixture of other gases.\nmilk is proteins, fats, lactose, and various vitamins and minerals.\nBronze is various alloys of copper and tin and some bronze will contain other metals too.\nSugar is a sweet cystalline or powder derived from sucrose and lactose obtained mainly from sugar cane and sugar beets.\nSo in all technicality the answer would be E. no of the above.

What is the most abundent gas in 'AIR'\n\nAnswer: Nitrogen\n\nMany people will be tempted to say Oxygen, but that only makes up 21%.  Nitrogen makes up 78%
