This may not be as spectacular as you migh imagine. If one litre of liquid nitrogen turned to gas, then it would simply be no longer the liquid form of nitrogen, but the gas form of it. This starts to happen immediately: its te smoke like stuff coming of the liquid nitrogen. Nitrogen in its gas form is a normal part of our atmosphere, we need it to breathe, so one litre of LIQUID nitrogen turning to GAS nitrogen will not do anything cool., You need to put something in the liquid nitrogen, and as nitrogen can only be liquid at a very low temperature, what ever you put in it, will freeze and if you hit it it will break. Dont get any on you: it wil freeze your flesh off

To convert liquid nitrogen to nitrogen gas, you simply need to allow the liquid nitrogen to evaporate at room temperature. Liquid nitrogen has a boiling point of -196 degrees Celsius, so when it is exposed to higher temperatures, it quickly turns into nitrogen gas. Just make sure to vent any pressure build-up safely if the container is sealed.
Exactly the same way you convert liquid water to water gas (steam):
Warm it up until it reaches the boiling temperature.
For water, that's 212 degrees above zero, Fahrenheit.
For nitrogen, it's 320 degrees below zero, Fahrenheit.
Liquid nitrogen changes to a gas when it gets warm enough. The temperature varies only slightly with pressure; at normal atmospheric pressure it is 77K, or in degrees Celsius -196.
because nitrogen is less compressible due dominace of repulsive forces between the molecules
Nitrogen becomes a liquid when it is cooled to below -196 °C (-321 °F).
(The industrial production is by liquefying air, then separating the nitrogen.)
Liquid nitrogen can evaporate because its boiling point is very low at -196 degrees Celsius. When exposed to higher temperatures, it can quickly vaporize into nitrogen gas.
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.
Liquid nitrogen is typically available for purchase from gas suppliers, welding supply stores, or industrial gas companies. However, it is important to adhere to proper safety protocols when handling and storing liquid nitrogen.
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.
Nitrogen-fixing bacteria get nitrogen from the atmosphere, specifically from nitrogen gas (N2). They convert this nitrogen gas into a form that plants can use, such as ammonia or nitrate, through a process called nitrogen fixation.
