Question 233

A puddle of water is evaporating on a sunny day. Which statement correctly describes the process of evaporation and how it differs from boiling?

A

Evaporation occurs at any temperature and only from the surface of the liquid, whereas boiling occurs at a specific temperature throughout the liquid.

B

Evaporation occurs only at the boiling point and from the surface of the liquid, whereas boiling occurs at any temperature throughout the liquid.

C

Evaporation occurs at any temperature and throughout the entire volume of the liquid, whereas boiling only occurs at the surface.

D

Both evaporation and boiling only involve molecules with average kinetic energy escaping from the surface of the liquid.
