Nitrogen is a liquid when it is cooled to a temperature between minus 346 degrees Fahrenheit and minus 320.44 degrees Fahrenheit. Liquid nitrogen resembles water when it boils, but when it is colder than minus 346 degrees, it turns into a solid.
Liquid nitrogen is a compact and colorless liquid that can be used for a wide variety of purposes. It is used in cryotherapy to help remove skin warts and potentially malignant skin lesions. It can also be used to store animal cells for use in laboratories, and it is frequently used to keep food frozen while it is being transported.
