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 else can I help you with?
How can you get nitrogen out of the air?
Nitrogen can be separated from air through a process called fractional distillation, which takes advantage of the different boiling points of nitrogen and oxygen. During this process, air is cooled and condensed into liquid form, then gradually heated to separate nitrogen from other components in the air.
Is Nitrogen and oxygen a homogeneous mixture?
No, nitrogen and oxygen are not a homogeneous mixture. They are two separate gases that can exist in the air as a uniform mixture.
What processes are oxygen and nitrogen obtained from the air?
Oxygen and nitrogen are obtained from air primarily through fractional distillation or liquefaction. In these processes, air is cooled and compressed to separate its components based on their boiling points. Nitrogen boils at a lower temperature than oxygen, allowing for their separation.
How do you make nitrogen gas?
Nitrogen gas is made by separating it from the air through a process called fractional distillation. This involves cooling and compressing air to turn it into a liquid, then gradually warming it up to separate the different components, with nitrogen being one of them.
What does oxygen oxygen nitrogen make?
Oxygen and nitrogen will not directly chemically react with each other under normal conditions. They will typically stay as separate molecules in the air.

How can nitrogen be extracted from air?
Nitrogen can be extracted from air through a process called fractional distillation. This involves cooling the air to liquefy it, then gradually warming it up to separate the nitrogen from other gases like oxygen and argon.
Is Nitrogen and oxygen a homogeneous mixture?
No, nitrogen and oxygen are not a homogeneous mixture. They are two separate gases that can exist in the air as a uniform mixture.
How can one extract nitrogen from air at home?
One way to extract nitrogen from air at home is through a process called fractional distillation. This involves cooling the air to liquefy it, then gradually warming it up to separate the different components, including nitrogen. The nitrogen can then be collected as a gas.

One can create nitrogen gas by separating it from the air through a process called fractional distillation. This involves cooling and compressing air to liquefy it, then gradually warming it up to separate the different components, including nitrogen gas.
How do you separate nitrogen gas from a mixture of nitrogen gas and liquid nitrogen?
You can separate nitrogen gas from liquid nitrogen by allowing the liquid nitrogen to evaporate at room temperature or by heating it to increase the rate of evaporation. The nitrogen gas will separate from the liquid nitrogen as it evaporates, leaving behind the liquid nitrogen.
How can nitrogen be retrieved from air?
One way is to liquify air using high pressure and low temperature, then fractional distillation to separate the air into its components, including nitogen.
Does nitrogen contain air?
Nitrogen doesn't contain air, but the air contains Nitrogen.
What is the percent if the air is nitrogen?
Our air is about 79% Nitrogen.
