Kinetic particle model of matter — practice question

As a liquid evaporates, some of its molecules leave the liquid. The temperature of what is left changes. What happens to the temperature, and from where do the molecules leave?

  • Atemperature of liquid decreases; molecules escape from everywhere within the liquid
  • Btemperature of liquid decreases; molecules escape from the surface only
  • Ctemperature of liquid increases; molecules escape from everywhere within the liquid
  • Dtemperature of liquid increases; molecules escape from the surface only
