Professor James Dewar, a Scottish scientist, is credited with inventing the vacuum flask that allowed for the storage and transportation of liquid gases, including liquid nitrogen. Dewar's work laid the foundation for the development and use of liquid nitrogen in various fields, such as science, medicine, and industry.

When was was liquid nitrogen invented?
Liquid nitrogen was first produced by Polish scientists Zygmunt Wróblewski and Karol Olszewski in 1883. They managed to liquefy nitrogen at a temperature of 77 K (-196 °C, -321 °F).
What will be the state of liquid nitrogen after boiling?
After boiling, liquid nitrogen will turn into nitrogen gas.
What is colder - liquid nitrogen or liquid heluim?
Liquid helium is colder than liquid nitrogen. Liquid nitrogen boils at -196°C, while liquid helium boils at -269°C.
What is the melting point of liquid nitrogen?
Liquid nitrogen has no melting point. A melting point is the temperature when a solid turns into a liquid. Since liquid nitrogen is already a liquid, it has no melting point. It is already melted, compared to solid nitrogen.
Is liquid nitrogen a pure substance or a mixture?
Liquid nitrogen is a pure substance because it consists of only nitrogen molecules in liquid form.

After boiling, liquid nitrogen will turn into nitrogen gas.
What phase is liquid nitrogen in at room temperature?
Liquid nitrogen is liquid.
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.
What is colder - liquid nitrogen or liquid heluim?
Liquid helium is colder than liquid nitrogen. Liquid nitrogen boils at -196°C, while liquid helium boils at -269°C.
If liquid nitrogen freezes everything why is itself a liquid?
liquid nitrogen will not freeze everything. Hydrogen and helium will remain a gas when exposed to liquid nitrogen.
What is the solvent and solute in 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.
How can prepare nitrogen liquid?
The liquid nitrogen is prepared by fractional distillation of liquid air.
Is liquid nitrogen a fluid or a solid?
liquid nitrogen is probably a fluid.
What if liquid nitrogen was poured on the floor?
Liquid nitrogen is quickly evaporated.
Is liquid nitrogen an element or compound?
Liquid nitrogen is a compound, specifically dinitrogen (N2), since it consists of nitrogen molecules made up of two nitrogen atoms bonded together. It is the liquid form of the nitrogen gas found in our atmosphere.
What is the melting point of liquid nitrogen?
Liquid nitrogen has no melting point. A melting point is the temperature when a solid turns into a liquid. Since liquid nitrogen is already a liquid, it has no melting point. It is already melted, compared to solid nitrogen.
