What happens when air molcules are cooled?

As air molecules are cooled, they condense and form a liquid, and if cooled even further, will form a solid.


How do you turn nitrogen from a gas to a liquid?

in general you need to two things: But Liquid Nitrogen is not made this way. 1st it needs to be cooled very cold. Then it needs to be compressed. The proccess usually does this both at the same time, Cooled Nitrogen is run through a compressor and then cooled agian, and then super cooled to create Liquid. It is produced using a proccess called fractional distilation of air resulting in Liquid Oxegen and Liquid Nitrogen.


How do you separate nitrogen from the air?

By cooling and pressing air and then expanding it you can separate liquid nitrogen from air.AnswerThe air must be repeatedly cooled and compressed until it liquefies. The liquid air is then fractionated (allowed to evaporate under controlled conditions) so that each component (oxygen, nitrogen, argon) is released as a pure stream. The Nitrogen stream is collected and re-cooled to be a liquid for storage and handling as the volume of the liquid is much less than the gaseous nitrogen.


What substance takes up so much water from the air that it forms a liquid solution?

A substance that takes up so much water from the air that it forms a liquid solution is called a deliquescent. It is a substance that tends to absorb moisture from the air and dissolve in it.


If air is compressed and cooled sufficiently it becomes a substance?

If air is compressed and cooled, the temperature of the air will become negative. Now depending on how much humidity there is in that air being compressed we might get some water droplets as it is being cooled. Carbon dioxide when compressed and cooled we get dry ice.
