During evaporation, the temperature of a liquid decreases. Which statement correctly explains why the temperature of the remaining liquid falls?
The molecules with the lowest kinetic energy escape first, increasing the temperature of the escaping vapor.
The average spacing between the remaining molecules increases, which reduces their temperature.
The most energetic molecules escape from the liquid surface, reducing the average kinetic energy of the remaining molecules.
The escaping molecules perform work on the atmosphere, which cools the liquid.
