select the correct answer. what happens to the temperature of the liquid in a cup of water as some of the water evaporates? a. the temperature increases because there are fewer molecules to share energy between. b. the temperature decreases because new molecular bonds form. c. the temperature decreases because the most energetic molecules escape. d. the temperature increases because the vapor pressure increases.

select the correct answer. what happens to the temperature of the liquid in a cup of water as some of the water evaporates? a. the temperature increases because there are fewer molecules to share energy between. b. the temperature decreases because new molecular bonds form. c. the temperature decreases because the most energetic molecules escape. d. the temperature increases because the vapor pressure increases.

Answer

Brief Explanations:

Evaporation is a cooling - process. The most energetic water molecules have enough kinetic energy to escape the liquid phase and become vapor. As these high - energy molecules leave, the average kinetic energy of the remaining liquid molecules decreases. Since temperature is a measure of the average kinetic energy of molecules, the temperature of the liquid decreases.

Answer:

C. The temperature decreases because the most energetic molecules escape.
