The temperature of the liquid nitrogen is so low that it freezes water molecules from the air which forms as ice at the opening.
About the temperature of dry ice. It is the same as putting frozen water (ice) in a glass of water. The temperature of the ice and water will be about equal to the freezing point of water. Alcohol is used because it has a freezing point lower than H2O, if you put dry ice in water everything will freeze.
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.
When you put a banana in liquid nitrogen, it freezes instantly due to the extremely low temperature of liquid nitrogen (-196°C). The banana becomes extremely brittle and can shatter easily. Once removed from the liquid nitrogen and allowed to thaw, the banana will turn mushy and soft as the cells have been damaged by the freezing process.
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 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.
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.
Liquid nitrogen can cause water to freeze instantly when pumped into it. Liquid nitrogen has a very low temperature of -320°F (-196°C), causing the water to freeze rapidly upon contact.

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.
Some examples of liquids that do not freeze at typical temperatures include liquid nitrogen, liquid helium, and liquid mercury.
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.
Yes, liquid nitrogen has a temperature of around -320°F (-196°C), which is low enough to freeze water almost instantly upon contact. When liquid nitrogen comes into contact with water, the water rapidly freezes and forms ice.
Yes, if you somehow manage to breathe liquid nitrogen or some other refrigerant.
You can't freeze gasoline at home, unless you have some liquid nitrogen around.
