Evaporation of a liquid takes place at temperature:

Detailed Solution for Test: Evaporation And Condensation - Question 4

Correct option is D. 
Evaporation is the process of a liquid turning into vapor at any temperature below its boiling point. During evaporation, particles escape from the surface of the liquid to form gas. Evaporation is different from boiling because it only occurs at the surface of the liquid and is very slow.
