Question

Which of the following option correctly differentiates between evaporation and boiling?

• A. Evaporation takes place only at ${100}^{\circ }C$.
• B. Evaporation takes place at any temperature that is below boiling point.
• C. Evaporation takes place at any temperature above boiling point.
• D. Both evaporation and boiling are same.

Answer 1

The correct option is B

Evaporation takes place at any temperature that is below boiling point.

Evaporation is the process through which a liquid is converted into its vapor form without even reaching the boiling point. It is a surface phenomenon. For example, drying of clothes. Whereas, boiling is a bulk phenomenon which takes places throughout the liquid in which a liquid is converted to its vapor form at its boiling temperature. For example, boiling water at 100 ${}^{o}C$.
