Water is the chemical compound . Its bent molecular geometry gives it a permanent electric dipole moment, and its molecules form an extensive, changing network of hydrogen bonds in the liquid.
These interactions help explain its comparatively high boiling point for such a small molecule, its effectiveness as a solvent for many ions, and the lower density of ordinary ice than liquid water. Water can act as both a proton donor and acceptor, making it central to acid-base chemistry. Its phase and thermodynamic properties depend on temperature and pressure.
