Question

On the basis of what happens on molecular level, why does evaporation lower the temperature of a liquid? Select all that apply s. a· The molecules with low kinetic energy are the first to evaporate. (D Themoleculeswith high kinetic energy are the first to evaporate. As the molecules evaporate, the average kinetic energy of the remaining molecules in the liquid decreases, lowering the temperature. d. As the molecules evaporate, the average kinetic energy of the remaining molecules in the liquid increases, lowering the temperature None of these are correct. e.

Explanation / Answer

Answer is B. When the temperature increases, the high kinetic energy molecules start to evaporate first.
