Good article.

Certain tempting things left unexplained though :) . Like, why properties of H, He and Ne are such that they are at this part of their diagram at normal conditions? Or where dispersion bonding stores the kinetic energy - when two atoms bond this way, both momentum and energy should be preserved, so some places to put excess of energy should be present, otherwise the pair should be unstable. Like, requiring another external collision to dissipate that energy.

High school physics also teaches adiabatic processes, which can suggest a temperature change. But those are all minor comments to the idea that there are models, and they are imprecise, but still could be useful.

This is the wrong question. You should, rather, ask: “under what conditions are things at various parts of the diagram?” “Normal conditions” are really just happenstance, if you're considering physics; stars and the immense void of space are both much more common than room temperature, room pressure.

- H and He (and Ne ?) are small.

- The energy is stored in the bond ?
