Answer: C. The temperature decreases because the most energetic molecules escape.

Explanation: Evaporation is surface phenomenon in which liquid molecules gain energy from surrounding molecules and thus these high energy molecules escape from the surface in the form of vapors thus leaving low energy molecules in the system.

As the kinetic energy of the left molecules decreases, the temperature of the molecules decreases as kinetic energy is directly proportional to temperature. Thus low temperature results in cooling of the system.

K.E=\frac{3}{2}\times RT

R= gas constant

T= temperature
