Question 244

During the process of evaporation, the more energetic molecules escape from the surface of a liquid into the atmosphere.

How does this escape affect the average kinetic energy of the remaining molecules, and the temperature of the remaining liquid?

A

The average kinetic energy increases, and the temperature increases.

B

The average kinetic energy increases, and the temperature decreases.

C

The average kinetic energy decreases, and the temperature increases.

D

The average kinetic energy decreases, and the temperature decreases.
