Fun fact: this is how they separate oxygen, nitrogen, and argon from air. You cool it to a liquid, and the. Slowly heat it back up. Nitrogen boils off first around 77K, then Argon around 83K, then Oxygen at 90K.
I find this so cool, even though it’s like “oh yeah. Just like distilling alcohol or petroleum”… But… Like super cold…

Right?! How cool is it that we can literally chill the atmospheric soup that we all stroll around in, then separate that into its components.
