Describe some unusual properties of water.

Explanation

Some unusual properties of water are as follows:
a. The peculiar properties of water in condensed form are due to the presence of extensive hydrogen bonding between water molecules.
b. The abnormally high freezing point, boiling point, heat of vapourisation and heat of fussion as compared the periodic table e.g. `H_(2)S,H_(2)Se` are due to hydrogen bonding.
c. It has higher specific heat, thermal conductivity and surface tension than most other liquids.
d. These properties allow water to play a vital role in the biosphere. its is an excellent solvent.
e. Under higher pressure and temperature, it behaves like a non-polar solvent and dissolves organic compounds.
f. It freezes to form ice-the crystalline form of water. ice has lesser density than water and prevent aquatic life.
