In general covalent bonds determine: molecular shape, bond energies, chemical properties, while intermolecular forces (non-covalent bonds) influence the physical properties of liquids and solids. The kinetic molecular theory of gases gives a reasonably accurate description of the behavior of gases.

There are 3 different forms of water, or H 2 O: solid (ice), liquid (water), and gas (steam). Because water seems so ubiquitous, many people are unaware of the unusual and unique properties of water, including: Boiling Point and Freezing Point; Surface Tension, Heat of Vaporization, and Vapor Pressure; Viscosity and Cohesion; Solid State ...
The extra bonding between water molecules also gives liquid water a large specific heat capacity. This high heat capacity makes water a good heat storage medium (coolant) and heat shield.
In cohesion, water molecules are attracted to each other (because of hydrogen bonding), keeping the molecules together at the liquid-gas (water-air) interface, although there is no more room in the glass.
Special properties of water are its high heat capacity and heat of vaporization, its ability to dissolve polar molecules, its cohesive and adhesive properties, and its dissociation into ions that leads to the generation of pH. Understanding these characteristics of water helps to elucidate its importance in maintaining life. Water’s Polarity.
The properties of water. “From water does all life begin.”. —OC Bible, 457 Kalima. 1. Static properties. The chemical formula of water is H2O. Its molecu-lar structure is roughly as shown below: The density of water, at standard temperature and pressure is, by definition. ρ = 1 gm ⁄ cm3 = 103 kg ⁄ m3 .
Water molecules form hydrogen bonds and are extremely polar. The five main properties of water are its high polarity, high specific heat, high heat of vaporization, low density as a solid, and attraction to other polar molecules.
