Examples of Evaporation

  1. After sweating, we get a cool feeling on our skin. This is due to the evaporation of the sweat generated from our bodies.
  2. Washed or wet clothes are dried by evaporation. When the clothes are hung outside in the sun, due to the heat of the sun, the water droplets present in the clothes get dried away due to evaporation.
  3. Crystals are formed by creating a mother solution, in which when the solvent evaporates, a saturated solution is left behind. Once this saturated solution cools down a crystal is formed.
  4. In food processing industries, the process of evaporation is used to dry out all the liquid contents and make the concentration of solid content high.
  5. Salt crystals are formed by creating a water solution, in which the deposit settles down and the liquid above is left to evaporate. Once the entire volume of the liquid gets evaporated we are left with the salt crystal present below.
  6. Acetone is an organic compound that evaporates at a very low temperature, hence it is used as nail polish remover.
  7. Similarly, spirits are also compounds that evaporate at a very low temperature, hence it is used to sterilize the skin where a syringe for vaccines or blood collection needs to be introduced.
  8. In the case of distillation, the mixtures with different boiling points are heated until one of the mixtures gets evaporated, hence the given mixtures are separated.
  9. Evaporation occurs in the water cycle in which the water from any water body on the surface of the earth is evaporated into the air. This water when cools down causes rain.
  10. The generation of steam in a hot cup of tea or coffee is caused due to evaporation.
