There’s a conjecture attributable to a man named Robin J. Presently, which implies the liquid-vapor spinodal intersects the curve of density maxima! And it does so at destructive pressures. I don’t truly understand the importance of this, however it certainly sounds chilly. Gargantuan-chilly.

Any reason why someone would bother doing this? I can see why someone might want to change words to avoid some crude plagiarism-detection algorithms, but what’s the point if you create a bunch of ridiculous bullshit?

A common mistake. I’ll fix it.

This goes eventually somewhat into the direction of what amarashiki was sort of thinking of, if one thinks of p as some average ??

But this estimate is ‘naive’ because it assumes the 6 out of 16 hydrogen configurations for oxygen atoms in the second set can be independently chosen, which is false. More complex methods can be employed to better approximate the exact number of possible configurations, and achieve results closer to measured values.

Did they do time series also at constant temperature ?

If one assumes that no heat energy would be transferred to a block of ice (I don’t know wether this could be seen as applying to the experiment, i.e. if this is an adiabatic process) and moreover if the block could be seen as isolated (pressure, volume) (again I don’t know to which extend this would apply here) then within a certain time there should on average be more disorder and this may refer not only to the hydrogen atoms but also to the oxygen atoms, moreover the disorder change should go together with different pressure, temperature and volume change of the block, i.e. dS = 1/T p dV

There’s also an uncountable infinity of other patterns that all give you equally dense packings. For example:

-a-b-a-c-b-a-c-b-c-b-a-c-

But then since the volume stays the same, where would the work come from? By sucking heat from the oil bath?
