ABSTRACT
It is worth noting that an essential particularity of water lies in the fact that at ambient temperature, it should exist as a solid element rather than a liquid. Paradoxically, thermodynamic studies show that at ambient temperature, water resembles a solid and not a liquid. In fact, this paradox can be explained by detailed study of the structure of the hydrogen bond, which is nothing other than the intramolecular oxygen-hydrogenoxygen bond. It is also this hydrogen bond that explains why the fluidity of water in the liquid state increases under compression, which is contrary to what is observed for other elements.
