Water is very important; all organisms are made up mostly of water, and live in an environment dominated by water. Most cells are surrounded by water, and the cells are about 70-95% of water. 75% of the Earth surface is made up of water. Water is a most unusual molecule, with physical and chemical properties found in no other material. Water has unique properties, which include cohesion, adhesion, surface tension, polarity, solvent, high specific heat, and transparency.
Water is a polar molecule because there is an uneven distribution of electron density. The water molecule contains two hydrogen atoms joining to the oxygen atom by covalent bonds. ... The attraction of the water molecules is electrical; the positive hydrogen molecule is attracted to the negative oxygen molecule, which is called hydrogen bond. Each water molecule can have a maximum of four hydrogen bonds. Many unique properties of water are due to the hydrogen bonds.
Water is sticky also because of the hydrogen bonding.
