Question

A liquid can change into vapour, even at a temperature below its boiling
point. Give reasons to substantiate this hypothesis.

Answer 1

Answer:

In the case of liquids, a small fraction of particles at the surface, having higher kinetic energy, is able to break away from the forces of attraction of other particles and gets converted into vapour. This phenomenon of change of a liquid into vapours at any temperature below its boiling point is called evaporation.
