Nitrogen only remains a liquid at very low temperatures (-196oc) above this temperature the liquid will return to a gas, so warm it us is the answer, although because of the extreme cold temperatures and the asphyxiating nature of the gas it needs to done safely and only by trained personnel using the correct equipment.
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.
By fractional distillation. Allow liquid air to get less cold. At around 77.4K, nitrogen will boil off while oxygen will remain liquid. The temperature will begin to rise again when all the nitrogen has boiled off.
Liquid nitrogen is liquid.
There is neither a solvent nor solute in liquid nitrogen as it is not a solution. Liquid nitrogen is pure elementalnitrogen in liquid form.
Liquid nitrogen is quickly evaporated.

If you pour liquid helium into liquid nitrogen, the helium will not mix with the nitrogen and will instead form separate layers. Helium is lighter than nitrogen and has a lower boiling point, so the helium will tend to float on top of the nitrogen.

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.
when the liquid nitrogen is boiled then it will turn into nitrogen gas.
Liquid nitrogen is colder than liquid oxygen. You use the liquid nitrogen to chill the oxygen in the air and liquid oxygen will form. Liquid water and dry Ice (CO2) should also form due to their presence as well, but not in large quantity. WARNING!! High concentrations of oxygen should be considered dangerous. When exposed to a small ignition source, it can cause flammable materials to combust much like an explosion, and will cause normally non flammable materials to burn readily. Human flesh burns better than wood after being exposed to 100% oxygen for a period of time. Please be careful.
Liquid nitrogen is liquid.
Liquid helium is a lot colder than liquid nitrogen.
One can create nitrogen through a process called fractional distillation of liquid air. This method involves cooling and compressing air to turn it into a liquid, then gradually heating it up to separate the different components, including nitrogen.
liquid nitrogen will not freeze everything. Hydrogen and helium will remain a gas when exposed to liquid nitrogen.
There is neither a solvent nor solute in liquid nitrogen as it is not a solution. Liquid nitrogen is pure elementalnitrogen in liquid form.
The liquid nitrogen is prepared by fractional distillation of liquid air.
