can we solidify air???

Answer 1

Yes! We just did this last week as a chemistry demonstration.
Note: Liquid nitrogen will cause serious frostbite if in contact with skin.

Air is made of nitrogen (mostly) and oxygen. We took a balloon and filled it with air. With a pair of tongs, we dropped the balloon into a container of liquid nitrogen (really, really cold, -196 C). The balloon shriveled up, really tiny because the air liquefied (just like liquid nitrogen). When the balloon was pulled from the liquid nitrogen and returned to room temperature, the air went from a liquid to a gas.

To get to a solid, you would need to decrease the temperature below -253 C (20 K). Not really practical.

Answer 2

Air has several components. Some like helium ( very minor part) can be solidified at the lowest temperature very close the absolute zero. All the other gas like nitrogen etc can be solidified at temperature above solid helium temperature

Answer 3

You are not clear : solidify air around you in the atmosphere, or collect air in a flask or a cylinder and solidify. Theoretically it can be done by lowering temperatures or/and increasing pressure.
Practically, I dont think you can solidify or liquefy the atmosphere..

Answer 4

Not really. All these people are correct when they say that we can liquefy the gasses in air, and even freeze them solid under enough pressure in addition to freezing. But they would separate because they have different liquefying temperatures and different freezing temperatures. Because 'air' is a mixture of gasses, it cannot be frozen and remain mixed. Sorry.

The same principle is what was used to make 'winter wine' before distillation was discovered. You would put out wine in shallow pans in the coldest part of the winter. Some of the water would freeze; you would throw away the ice and the liquid that remained would contain a higher ratio of alcohol to water. They separated because they freeze at different temperatures.

Answer 5

Pretty simple remember Charles law,Volume is directly related to temperature.If u observe the graph of Charles law it cuts X-axis (volume) at -273 deg centigrade,ie 0 kelvin.It means that at this particular temperature no gas can exist in gaseous form,either it turns into liquid or it turns into solid.But this is simply theoritical and cannot be done practically.For this to happen all gases in atmosphere should be ideal.No ideal gas exists in this universe.Hence it is not possible to solidify air.

Answer 6

Well, air is made up of:

Nitrogen (78%), Oxygen (20%), Argon (1%), Trace compounds like CO2, water vapor, ect (1%)

Here are the freezing points of all those constituents:
Nitrogen: 63K (-346 F)
Oxygen: 58 K (-355 F)
Argon: 84 K (-308 F)
CO2: 195 K (-108 F)
Water vapor: 273 K (32 F)

This is assuming a standard pressure of 1 atm of course.

Answer 7

according to chemistry and thermochemical data of air composition, we can have solid air, BUT,... this is theorically,... in fact we must have the temperature below 15 degree in Kelvin unit to solidify air, and this is not practically really. we need some special equipments and high quality selection of material can reach and bear this condition.

Answer 8

Yes. Freezing it is one way, but at room temperature if you increase the pressure to about 1000 tonnes per square centimetre, you'd squash a roomful of air into a block of waxy white solid about as big as six bricks.

Answer 9

yes we can
we can directly or indirectly solidify air
air contains different gases like CO2, N2,O2,H2O e.t.c
e.g if we wann to have ice from air we can condense air to water and freeze it to ice or we can directly freeze ais if u know phase diagram of water
we just keep temperature at -10oC and if we reduce pressure to 10-20mmHg we will directly get ice from air. similarly we can do for other gasas in air

Answer 10

Liquid metallic hydrogen, which the planets Jupiter and Saturn are made of, is not an earthly substance.

But would look much like the liquid metal Mercury here on earth.

So, yes.............. if we could produce enough pressure.
