Question 133

During the process of evaporation, liquid molecules transition to the gas phase. Which option correctly identifies where these escaping molecules leave from, and the resulting change in the average kinetic energy of the remaining molecules?

A

Escape location: throughout the body of the liquid; Average kinetic energy of remaining molecules: Decreases

B

Escape location: throughout the body of the liquid; Average kinetic energy of remaining molecules: Increases

C

Escape location: surface of the liquid; Average kinetic energy of remaining molecules: Decreases

D

Escape location: surface of the liquid; Average kinetic energy of remaining molecules: Increases
