Answer to Question 1

Answer: A

Answer to Question 2

Answer: Evaporation is the change of phase from liquid to gas. The molecules in the liquid most prone to make the transition and break through the surface to become a gas are the faster and more energetic molecules. So the molecules that evaporate are the faster, or more energetic. With selective removal of the more energetic molecules, a greater proportion of slower ones remain in the liquid. Hence the liquid is cooled.
