The reason that evaporation is a cooling process is
A)radiation of heat during the process.

C)the more energetic molecules escape the liquid.
D)all of the above
E)none of the above

Question

Quizplus · Accepted Answer

When more energetic molecules escape from the liquid, the average kinetic energy of the remaining molecules decrease, which causes a decrease in temperature. This is why evaporation is a cooling process. Radiation of heat and conduction/convection may occur during the process, but they are not the primary reason for the cooling effect.
