Biological Importance Of Water

Water is an essential part of life, it takes up between 60 and 95% of mass of living organisms, it plays an important part in cells and also many organisms live in water. I am going to talk about physical properties of water and the biological importance of water.

Physical properties of water

Hydrogen bonding is when a water molecule forms hydrogen bonds, it form with up to four other water molecules. Water is a polarized molecule, this means it can form hydrogen bonds with other water moles because hydrogen is slightly positively charged and oxygen is slightly negatively charged due to in water oxygen’s nucleus attracts the electrons more than the hydrogen’s nucleus.

High specific heat capacity

Water has a high specific heat capacity. The amount of heat (energy) in joules is required to raise the temperature of water by 1 degree.

 

High latent heat of vaporization

This is the measure of heat energy needed to vapourise water. It is hard to vapourise water because large amounts of heat is needed to break the hydrogen bonds, and also water has a high boiling point, even though it is a small molecule.

Cohesion and Surface tension

Hydrogen bonds make water molecules stick ...
