Water molecules are more attracted to each other than to air molecules and form a spherical shape to maximise
contact between water molecules, which leaves as few as possible exposed to the air.
But, in the 1930s, the famous chemist and Nobel laureate Linus Pauling created a long - lived controversy when he proposed that the hydrogen
bonds between water molecules would be affected by the sigma bonds within the water molecules and partially assume the identity of these bonds.
