Biology Notes: Water and its properties: Transparency and high heat of evapouration

ZIMSEC O Level Biology Notes: Properties and Biological significance of water

Property: High heat of vaporization

  • This is a measure of the heat energy required to vaporize a liquid to overcome the attractive forces between its molecules so that they can escape as a gas.
  • A relatively large amount of energy is needed to vaporize water.
  • This is due to the hydrogen bonding.

Biological role

  • The energy imparted to water molecules to vaporize them thus results in loss of energy from their surroundings.
  • Thus a cooling effect occurs.
  • This is made use in sweating and when dogs are panting.

Property: Transparency

Biological role: enables aquatic plants to photosynthesize.
