It is the process by which water changes from a liquid to a gaseous state. While the boiling point of water is 100oC, it evaporates very slowly at 0oC. When the temperature rises, the rate of evaporation increases with it. However, the rate at which water evaporates varies depending on the temperature and the amount of water that needs to be evaporated. Hence, the phenomenon of change of a liquid into vapours (gases) at any temperature below its boiling point is called evaporation.

1) Temperature:

  • As the temperature rises, the rate of evaporation rises as well.
  • At higher temperatures, molecules move faster; therefore, it is more likely for a molecule to have enough energy to break away from the liquid to become a gas.

2) Surface area:

  • As the surface area increases, the rate of evaporation also increases.
  • As more surface area is exposed to air, water molecules can absorb more heat energy from their surroundings.

3) Wind speed:

  • The rate of evaporation is directly proportional to wind speed. As the wind speed increases, the rate of evaporation also increases.
  • Higher wind speed leads to increased airflow over the liquid’s surface, reducing the formation of a humid air layer.

4) Humidity:

  • The rate of evaporation is inversely proportional to humidity. As the humidity decreases, the rate of evaporation increases and vice versa.
  • Higher humidity means less evaporation because the air already holds a lot of moisture content, so there is less room for more water to evaporate into the air. On the other hand, lower humidity leads to faster evaporation because air can take in more water vapour.
