Periodic Table Of States (opens in new tab)

Hitting the thing that looks like a play button actually toggles the video visibility.

The scientist who put this together probably only tested it on large monitors. I had the same experience on my laptop's main display but on my (larger) external monitor the video floats below the table. Setting the browser zoom level to something like 75% manually also fixes the problem.

Cool site though, I wouldn't have guessed that there were any elements that remain solids at 6000K, or that helium remains a liquid even at absolute 0.

Based on the state transition temperature of Al, the table displays data at 1 atm.

What I don't get is how Carbon has a liquid state in that table. At 1 atm, solid carbon (not CO2) sublimates into its gaseous phase just below 4 kK.

.... i absolutely read this as "US states" .... now i feel really dumb

This explains it: https://en.wikipedia.org/wiki/Curie_temperature

In the ferromagnetic phase, the atoms are magnetically aligned and their magnetic fields adds up. If you increase the temperature past a certain point though, the atoms are jiggled enough that they can no longer stay aligned and they 'point' in random directions, and their magnetic fields cancel out.

This is a big problem in hard drives: If you increase the temerature of a hard drive the magnetic regions no longer maintain their magnetization and your data gets erased. A lot of hard drive technology (eg 'perpedicular recording') has been developed to solve this problem.

From what I remember of my rusty high school chemistry magnetism requires a certain relatively stable configuration of the valence electrons. I'm guessing that as temperature increases it's impossible for the atoms (or even just the electrons) to maintain that configuration because of the increased energy. The electrons might even get excited enough to jump to entirely different orbitals, but I'm not sure if it works that way.
