Model of hydrogen bonds (1) between molecules of water. Because of its polarity, a molecule of water in the liquid or solid state can form up to four hydrogen bonds with neighboring molecules. Hydrogen bonds are about ten times as strong as the Van der Waals force that attracts molecules to each other in most liquids.
Water molecules stay close to each other , due to the collective action of hydrogen bonds between water molecules. These hydrogen bonds are constantly breaking, with new bonds being formed with different water molecules; but at any given time in a sample of liquid water, a large portion of the molecules are held together by such bonds.

A water molecule contains one oxygen and two hydrogen atoms connected by covalent bonds. Water is a liquid at ambient conditions, but it often co-exists on Earth with its solid state, ice, and gaseous state (water vapor or steam).
A distinct state of matter can be defined as any set of states distinguished from any other set of states by a phase transition. Water can be said to have several distinct solid states. [ 7 ] The appearance of superconductivity is associated with a phase transition, so there are superconductive states.
Mesomorphic states: States of matter intermediate between solid and liquid. Plastic crystal : A molecular solid with long-range positional order but with constituent molecules retaining rotational freedom.
In 1988, predictions of the so-called superionic water state were made. [124] In superionic water, water molecules break apart and the oxygen ions crystallize into an evenly spaced lattice while the hydrogen ions float around freely within the oxygen lattice. [125]
Thermal image of a sink full of hot water with cold water being added, showing how the hot and the cold water flow into each other. Liquid is one of the four primary states of matter, with the others being solid, gas and plasma. A liquid is a fluid. Unlike a solid, the molecules in a liquid have a much greater freedom to move. The forces that ...
For molecules containing lone pairs, the true hybridization of these molecules depends on the amount of s and p characters of the central atom which is related to its electronegativity. "According to Bent's rule , as the substituent electronegativies increase, orbitals of greater p character will be directed towards those groups.
