Evaporation cools the liquid that is left behind because the molecules that leave the liquid during evaporation
A)have kinetic energy.
B)have greater than average speed.
C)have broken the bonds that held them in the liquid.
D)create vapor pressure.

Question

Quizplus · Accepted Answer

The molecules that leave the liquid during evaporation are those with greater than average speed, meaning they have higher kinetic energy. When these faster (and therefore, hotter) molecules leave, the average kinetic energy of the remaining molecules decreases, leading to a decrease in temperature of the liquid.
