Liquid nitrogen is simply this same gas, but cooled down until it became a liquid. There are three primary states of matter: Solid, liquid, and gas. Most elements can be found at any of these three states of matter. Which state of matter you find depends on two things: pressure and temperature. In chemistry, we have something called a phase diagram to help us visualize this idea. Lets look at ...
