    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…
