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

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
