Question

Evaporation is the process of changing liquid into vapour :

• A. at any temperature
• B. above its boiling point
• C. at its boiling point
• D. below its boiling point

Answer 1

The correct option is D below its boiling point

Evaporation is the process of changing liquid into vapour below B.P. (boiling point)

It is a type of vaporisation that occurs on the surface of liquid due to increase in temperature or pressure, it changes liquid into gaseous phase before reaching to boiling point. The surrounding gas must not be saturated by evaporating substance.
