Which of the following is true of evaporation? A. It is considered a cooling process and it raises the average kinetic energy of the liquid because the higher energy molecules turn to vapor. B. It is considered a heating process and it lowers the average kinetic energy of the liquid because the higher energy molecules turn to vapor. C. It is considered a cooling process and it lowers the average kinetic energy of the liquid because the higher energy molecules turn to vapor. D. It is considered a heating process and it lowers the average kinetic energy of the liquid because the lower energy molecules turn to vapor.

C

Explanation:

C. It is considered a cooling process and it lowers the average kinetic energy of the liquid because the higher energy molecules turn to vapor.

Moreso, evaporation does not increase the average kinetic energy because it is a surface phenomenon. Also, as molecules excape at a fast moving rate, the left over molecules have a lower kinetic energy and this consequently decreases the temperature of the liquid.

When molecules absorbs heat, the evaporate and this phenomental process provides cooling in the system

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
