What is liquid nitrogen used for?
Liquid nitrogen, which has a boiling point of -196C, is used for a variety of things, such as a coolant for computers, in medicine to remove unwanted skin, warts and pre-cancerous cells, and in cryogenics, where scientists study the effect of very cold temperatures on materials. It has also become increasingly common at top restaurants as ...
What happens when liquids are in contact with a mass significantly hotter than the boiling point?
He says the delay in feeling the cold is down to the "Leidenfrost effect" - which happens when a liquid, in near contact with a mass significantly hotter than the liquid's boiling point, produces an insulating vapour layer. But he agrees a mouthful of liquid nitrogen - which would turn into about 25 litres of gas - could do "catastrophic damage".
Can you swallow liquid nitrogen?
But Dr Alex Valavanis, a research fellow at the Institute of Microwaves and Photonics, at the University of Leeds, believes it would be perfectly possible for someone to swallow a mouthful before they became aware of any ill effects, as liquid nitrogen "does not immediately feel cold".
Is liquid nitrogen a gas?
Professor Peter Barham, from the University of Bristol's School of Physics, says liquid nitrogen is "simply the harmless gas nitrogen, which has been cooled to such a low temperature that it becomes a liquid".

But Professor Barham adds that just as no-one would drink boiling water or oil, or pour it over themselves , no-one should ingest liquid nitrogen. It is also essential that all the liquid has evaporated before any food or drink that has been prepared with liquid nitrogen is used, he says.
Can liquefied gas cause frostbite?
But he says the liquefied gas, which is intensely cold, can cause frostbite or cryogenic burns if it is not used, and handled, properly. For laboratory personnel in particular, there is also the risk of asphyxiation if liquid nitrogen - which is colourless, odourless and tasteless - is used or spilled in a confined space.
What happens when you expose liquid nitrogen to the air?
When liquid nitrogen is exposed to the air, it can turn into a gas. Oxygen levels can drop when this happens and can lead to headaches, lightheadedness and even the loss of consciousness.
Why does liquid nitrogen boil?
Liquid nitrogen is so cold that it freezes anything it touches, according to the University of Wisconsin-Madison. It clocks in around 320 degrees below freezing. Because it's so cold, liquid nitrogen immediately boils when it touches anything room temperature, which is what causes the cloudy smoke seen in fancy cocktails and frozen desserts.
