When a liquid evaporates, some of its molecules escape from its surface into the gaseous state. Which statement correctly describes the effect of this process on the remaining liquid?
The average kinetic energy of the remaining molecules increases, causing the temperature of the liquid to rise.
The average kinetic energy of the remaining molecules decreases, causing the temperature of the liquid to rise.
The average kinetic energy of the remaining molecules increases, causing the temperature of the liquid to fall.
The average kinetic energy of the remaining molecules decreases, causing the temperature of the liquid to fall.
