The temperature of the liquid nitrogen is so low that it freezes water molecules from the air which forms as ice at the opening.
Why does liquid nitrogen freez ?
its particles freeze to make it solid
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.
Liquid nitrogen is not dry ice. Dry ice is a solid form of carbon dioxide and liquid nitrogen is pure nitrogen in liquid form. Dry ice is frozen nitrogen. Liquid nitrogen is also frozen nitrogen, but is also pressurized. That's why it's in large, steel boxes. Chur.
It is more simple to transport liquid nitrogen compared to gaseous nitrogen.
Liquid nitrogen is simply nitrogen gas in its liquid state. The stuff is so cold you can consider it like an acid if you are ever stupid enough to stick your finger in there without cryogenic protection. By immersing them in liquid nitrogen you can turn marshmallows hard as bullets, shatter flowers like glass, turn a soft peach into something that can hammer nails into wood, and a whole lot of other things.
liquid nitrogen will not freeze everything. Hydrogen and helium will remain a gas when exposed to liquid nitrogen.
No. The wind is composed of a small amount of water vapor and about 20% oxygen and about 80% nitrogen. The water vapor may freeze but the oxygen and the nitrogen cannot freeze at the temperature of liquid nitrogen. Oxygen has a much lower freezing point than liquid nitrogen and if the nitrogen were to be frozen, liquid nitrogen is not cold enough to freeze it...sort of like trying to make ice using cold water.
only in imaginationland
Of course, it is possible !
As a general rule, liquids don't freeze things. But the gas, Liquid Nitrogen, can freeze things.
If you dip them into liquid nitrogen (LIN) they will freeze instantly.
Liquid nitrogen
Under normal circumstances, liquid nitrogen is at a temperature of less than -196C - pretty cold!!!
Yes, liquid nitrogen exists. It is sold in strong, insulated containers and is used to instantly freeze biological specimens or tissue.
No. Liquid nitrogen is nothing like radioactive waste or a biological virus. It would freeze your hands off on contact.
If it contained any liquid, it would freeze. If it did not contain any liquid, it would get VERY cold.
Yes, if you somehow manage to breathe liquid nitrogen or some other refrigerant.
