Liquid nitrogen (LN 2) is nitrogen in a liquid state at low temperature. Liquid nitrogen has a boiling point of about −196 °C (−321 °F; 77 K). It is produced industrially by fractional distillation of liquid air .

The suggested values for solid densities refer to "near room temperature (r.t.)" by default. The suggested values for liquid densities refer to "at the melting point (m.p.)" by default. See also
At IUPAC standard temperature and pressure (0 °C and 100 kPa), dry air has a density of approximately 1.2754 kg/m 3. At 20 °C and 101.325 kPa, dry air has a density of 1.2041 kg/m 3 . At 70 °F and 14.696 psi , dry air has a density of 0.074887 lb / ft 3 .
Small changes in temperature will have a noticeable effect on specific volumes. The average density of human blood is 1060 kg/m 3. The specific volume that correlates to that density is 0.00094 m 3 /kg. Notice that the average specific volume of blood is almost identical to that of water: 0.00100 m 3 /kg. [2]

Densities using the following metric units all have exactly the same numerical value, one thousandth of the value in (kg/m 3). Liquid water has a density of about 1 kg/dm 3, making any of these SI units numerically convenient to use as most solids and liquids have densities between 0.1 and 20 kg/dm 3. kilogram per cubic decimetre (kg/dm 3)
Liquid nitrogen, a colourless fluid resembling water in appearance, but with 80.8% of the density (the density of liquid nitrogen at its boiling point is 0.808 g/mL), is a common cryogen. [50] Solid nitrogen has many crystalline modifications.
