Comment on Fahrenheit vs. Celsius vs. Kelvin

You’ll be shocked to learn that the distance in Kelvin is also adjusted to water “chemistry”, albeit changing the aggregate state seems more physics to me, since no molceules are reacting with each other.

Thankfully that has been redefined using the Boltzmann constant, so now anyone in the universe can agree on °C and K without needing to measure any Vienna standard ocean water.

  I was going to make a joke about how Austria is landlocked, how did we come up with the idea of making an ocean water standard.
  
  Apparently the IAEA which is headquartered here set that standard, for anyone else curious.

You can’t change the aggregate state of a single molecule, or how do you mean that? Excluding plasma.

  you can of a lot of molecules though. and tgat is classically “physics” rather than “chemistry”. Classical chemistry is reactiona between atoms or molecules to form new ones.
  
  If you get deeper into it, the lines between chemistry and physics blur anyways.

    Ah yes, now I understand your previous comment. My reading error, thanks.
