Like nitrogen gas it consists of two nitrogen atoms sharing covalent bonds n 2. An air compressor is used to compress filtered air to high pressure. Liquid nitrogen has a boiling point of 195 8 o c 320 5 o f. The high pressure gas is cooled back to ambient temperature and allowed to expand to a low pressure.

One unexpected bonus of pouring liquid nitrogen on the floor is that the floor gets a good cleaning. Pouring it on the floor was a fun way of disposing of the remains in the bottom of a dewar a hundred ml or so.
