During evaporation, some molecules escape from the surface of a liquid. Which statement correctly describes the effect on the remaining liquid?
The highest-energy molecules escape, so the average kinetic energy of the remaining molecules increases, increasing the liquid's temperature.
The highest-energy molecules escape, so the average kinetic energy of the remaining molecules decreases, decreasing the liquid's temperature.
The lowest-energy molecules escape, so the average kinetic energy of the remaining molecules increases, increasing the liquid's temperature.
The lowest-energy molecules escape, so the average kinetic energy of the remaining molecules decreases, decreasing the liquid's temperature.
