1. A body with exceptional properties
Water is used every day to wash, rinse, dissolve, dilute, heat, cook, cool... As a thermal fluid for utilities, as an ingredient and raw material, water is at the heart of all industrial processes. These realities are linked to the exceptional properties of water as a fluid.
1.1 A polarized molecule
Water is made up of one oxygen atom (O) and two hydrogen atoms (H). As the electronegativity of the oxygen atom is greater than that of the hydrogen atom, the O-H bonds are polarized, which, due to its angled shape, leads to polarization of the molecule (figure 1 ).
