Hydrogen Bond in Water Molecules
Water is the softest in the world, but its properties are unique, due to the hydrogen bonds between water molecules.
In water molecules, hydrogen atoms and oxygen atoms are connected by covalent bonds, but the electrons of hydrogen are biased towards oxygen, causing hydrogen to be positively charged and oxygen to be negatively charged. Hydrogen from neighboring water molecules and oxygen from other water molecules attract each other electrostatically, thus forming hydrogen bonds.
Hydrogen bonds have extraordinary effects between water molecules. Looking at its liquid state, hydrogen bonds make water molecules attract each other, causing water to have a higher boiling point and melting point. If there is no hydrogen bond between water molecules, the boiling point of water should be much lower than it is today, and it may be difficult to be liquid at room temperature, and the origin and development of life may be greatly affected.
And hydrogen bonds make water a hot topic. When a lot of heat is absorbed or released, the water temperature slows down. This property is of great significance for regulating the earth's climate. The ocean can store a huge amount of heat energy due to hydrogen bonds, which stabilizes the surface temperature.
Furthermore, the surface tension of water also depends on hydrogen bonds to maintain. The water surface is like an elastic film, which can be used by insects. This is the work of hydrogen bonds between water molecules.
In summary, hydrogen bonds between water molecules, although slight but heavy, affect the physical and chemical properties of water, and have an indelible effect on the survival of life and the earth's ecology.
