Visualize the evaporation process?


Evaporation is the transformation of a liquid into a gas. Condensation is the exact opposite of this process. Evaporation becomes a primary pathway for water to enter the water cycle when it moves from a liquid form to an atmospheric vapour state. When a little amount of water vapour enters the atmosphere via sublimation, this process occurs.

  • The melting of an ice cube is an instance of evaporation.
  • The evaporation of acetone, which is used to remove nail polish, is another example of evaporation.

Various steps of evaporation

There are four major phases in the water cycle. Evaporation, condensation, precipitation, and collecting all take place in the same way. Let’s have a look at the procedures for both of them. Evaporation occurs when the sun’s heat causes water from seas, lakes, streams, glaciers, and soils to rise into the air and change into water vapour.

Single effect evaporation

In single Effect evaporation, the dilute solution that should be concentrated is contacted only once with heat.

Multiple effect evaporation

In multiple effect evaporation, the energy obtained in the first stage is utilised in the second stage

Factors influence evaporation

  • The evaporation rate is influenced by a number of factors, including humidity, temperature, wind, and surface area.
  • Certain liquid molecules evaporate at a faster pace than others. However, liquids that boil at a very high temperature evaporate more slowly than liquids that boil at a lower temperature.

How to prevent evaporation?

Holding the water in the shade, adding ice or freezing it with refrigerated pipes, or limiting its exposure to light are all ways to cool it down. This lowers the kinetic energy available to the water molecules, slowing the rate of evaporation.
