Very cool... but where is pressure? I don't see even a mention of what pressure is being used.

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.

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.
Wow, didn't know magnetism also varies with temperature. Any simple explanation why?
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.
