It's so cold! If you touched it your finger would freeze up and would stop the blood getting to the finger and you would die (Or serious injuries). If you were unlucky to fall in an tub of it, you wouldn't stand a chance. I think this is right!
Well technically if it was frozen then it would not be a liquid. The reason why liquid nitrogen is dangerous is because of its low temperatures. To have nitrogen which is normally a gas to become a liquid you must make the temperature extremely low. If you stick anything into this liquid nitrogen it will freeze it. This is because it is below the freezing point for most organic structures but now below the freezing point for nitrogen. For nitrogen to become a solid the temperatures must go even lower.
when the liquid nitrogen is boiled then it will turn into nitrogen gas.
Liquid nitrogen is liquid.
Submerge it in liquid nitrogen. Heston Blumenthal, currently a 3 Michelin Star chef uses it. But liquid nitrogen is dangerous and protective equipment is essential.
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 helium is a lot colder than liquid 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.
Liquid nitrogen is quickly evaporated.
liquid nitrogen is probably a fluid.
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.
