Liquid Nitrogen Fact Sheet

At normal pressure (like the pressure of the room you’re sitting in now), liquid nitrogen boils at
77 K (or −320.4°F). That is why it looks like steaming, boiling water when it is poured – because
it IS boiling!
 Liquid nitrogen is made by condensing air
until it becomes a liquid.
 Nitrogen makes up 78% of the air you
breathe.
 Nitrogen is non-toxic, odorless, colorless
and non-flammable.

The chemical symbol for nitrogen liquid and gas is N2 (which is why we call it N2ice Cream (with
a silent 2 of course))!

Your body is 3% nitrogen by weight and you eat it in many common foods.

Liquid nitrogen weighs 6.745 pounds/gallon

The container that holds liquid nitrogen is called a dewar.
