10 interesting facts about the various properties of water

Water is a chemical substance which is made up of 2 hydrogen (H) atoms and a single oxygen (O) atom with the chemical formula H₂0.By the virtue of constituting about 70% of the human body weight, it is easily the most abundant substance in the body. Some of the interesting facts about the properties of water are:

1. The polar structure of water results in an unequal or asymmetric distribution of charge on its constituent atoms resulting in electro negativity difference between O and H. 
2. The electrostatic attraction between the O atom of one H₂0 molecule and the H atom of another nearby H20 molecule culminates in the formation of a hydrogen bond. 
3. The adhesion property of water is due to its polar nature. 
4. The cohesive nature of liquid water is a direct consequence of a network of these H-bonds. 
5. Specific heat of water and Heat of vaporization of water is 4.2 joules/gm and 2260 joules/gm. respectively. 
6. There are 3 physical states of water: solid, liquid and gas. 
7. Water has the 2^nd best heat conduction capability after mercury because of which lakes and ocean have almost same surface temperature. 
8. By having the unique property to dissolve different types of substances, it is referred to as the universal solvent. 
9. Every pull force is countered by a push force beneath the surface of the water. But at the surface, every 'down' pull does not have a counter 'up' pull which creates the phenomenon of surface tension. 
10. The ability of several insects to walk on water is as a result of surface tension.
