Question

The process of conversion of a liquid into its vapour at any temperature below its boiling point is called

• A. diffusion
• B. evaporation
• C. boiling
• D. condensation

Answer 1

The correct option is B evaporation

When a liquid changes into vapour at a temperature below its boiling point, the process is referred to as evaporation. Evaporation is a surface phenomenon in which particles from the surface gain enough energy to overcome the forces of attraction present in the liquid and change into the vapour state. Hence, the correct answer is option (b).
