) The dissociation energy (from the zero-point level) of ground-state O2 is 5.09 eV. There exists an electronically excited state of O2 whose zero-point level lies 6.21 eV above the zero-point level of the ground state. The ground-state molecule dissociates into two ground state O atoms, while the excited state of O2 dissociates into one O and one O* (electronically excited) atom. O* lies 1.97 eV above O. Sketch the potential energy curves and calculate the dissoc

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
