Liquid Nitrogen is extremely cold, and sits at about -321 degrees Fahrenheit, or about -196 degrees Celsius. It is very dangerous that it is this cold, which is why we state time and again throughout this write-up to use all necessary safety precautions.

Liquid nitrogen expands at a ratio of 1:694 at 20 degrees Celsius, and can lead to explosion if handled improperly. Nitrogen gas is lighter than room air, and can cause asphyxiation if oxygen levels are reduced below 21%. …

Liquid nitrogen is inert, colorless, odorless, non corrosive, nonflammable, and extremely cold. Nitrogen makes up the major portion of the atmosphere (78% by volume). Nitrogen is inert and will not support …

Hazards and properties. Liquid nitrogen is a colourless, odourless liquid with a boiling point of -196°C. At low temperatures the gas / vapour is heavier than air. Small amounts of liquid vaporise rapidly to produce large volumes of gas (1 litre of liquid nitrogen will produce 0.7m 3 of gas). Nitrogen gas is invisible - the cloudy vapour which ...

The liquid nitrogen vehicle also has the potential to be more economical to operate than electric vehicles, according to the UW researchers. Assuming a 10-cent-per-gallon price for mass-produced liquid nitrogen, they predict the LN2000 would cost about 4 cents per mile to drive compared with an estimated 7 cents-per-mile cost of driving ...

The vapor of liquid nitrogen can rapidly freeze skin tissue and eye fluid, resulting in cold burns, frostbite, and permanent eye damage even with brief exposures. Liquid nitrogen (LN2) is liquefied under high pressure and expands approximately 695 times in volume when it vaporizes. As a result, one liter of liquid can expand into 695 liters of gas.
