Question

Evaporation of a liquid occurs at

• A. It's boiling point
• B. room temperature
• C. all temperature
• D. below its boiling point

Answer 1

The correct option is D

below its boiling point

Evaporation — At a given temperature in any gas, liquid or solid, there are particles with different amounts of kinetic energy.

• 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 vapor.
• This phenomenon of change of a liquid into vapors at any temperature below its boiling point is called evaporation process of tunning from a liquid into a vapor
• It is a type of vaporization that occurs on the surface of a liquid below its boiling point
• It can be easily visualized when rain puddles “disappear” on a hot day
• When a liquid material becomes a gas, evaporation occurs

Thus, the option D is correct I:e below its boiling point
