Question

How does evaporation cause cooling?

Solution

Evaporation:-

  • Evaporation is a process in which a liquid changes into vapour without attaining its boiling point, and it causes natural cooling
  • When matter molecules shift phases from liquid to gas, they need energy to overcome their potential energy through kinetic energy.
  • Thus, the liquid absorbs energy from its surroundings and the molecules of the material constantly absorb heat energy from their environment, cooling them until they approach the boiling point, at which point they begin to break away from the liquid and transform into vapour.
  • When a molecule at the surface uses enough energy to exceed the vapour pressure, the liquid particles will escape and enter the surrounding air as a gas.
  • The energy taken from the vaporized liquid during evaporation lowers the temperature of the liquid.

Hence, evaporation causes a cooling effect.
