|What is the degrees in Fahrenheit of liquid
Liquid nitrogen is very, very cold. At everyday
temperatures, nitrogen is a gas. In fact, most of
the air we breathe is nitrogen. It becomes a
liquid at a temperature of -320.8 degrees
Fahrenheit. In other words, almost 321 degrees
It is useful to be able to compare
this with a substance like water.
becomes a liquid at 212 degrees Fahrenheit! Water
freezes into ice at 32 degrees Fahrenheit. That
makes liquid nitrogen 352 degrees Fahrenheit
colder than ice! That means that liquid nitrogen
is so cold that if you put your finger in it, it
would completely freeze.
Liquid nitrogen is very cold, as you know. It is
actually 320 degrees farenheit below zero. As you
may know there is a temperature (known as absolute
zero) which is as cold as anything can get. If we
start at the freezing point of water and work
towards absolute zero, liquid nitrogen is about
three quarters of the way to absolute zero. Very cold!
Liquid nitrogen at standard atmospheric pressure
(14.7PSI) boils at 77K, this is -196C or -321F.
You can convert Centigrade to Fahrenheit with the
simple formula: F = 32 + 9/5 * C
Nitrogen "boils" at 77 Kelvin, at 1 atmosphere of
pressure. The boiling point of a substance is that
temperature and pressure at which the substance is
changing from a liquid to a gas, or vice versa. So
when you pour liquid nitrogen from a dewar (that's
a container with really strong walls that keeps it
cold, like a very good thermos) it comes out
boiling, because under normal earth conditions,
nitrogen is a gas. 77 Kelvin is equivalent to
-196Celcius, or -320 Fahrenheit.
