This is a true story. a lawyer in bloomington, indiana, wanted to impress a judge with the high number of pcb molecules that a typical person takes in with each breath. he called prof. hites for this fact, but he did not have this information at hand. however, a student of his had recently determined that the flux of pcbs from the atmosphere to bloomington's surface averaged 50 μg m^(-2) y^(-1). you may assume that the area of bloomington is 100 square miles, that the deposition velocity of pcbs is 0.3 cm/s, and that the molecular weight of pcbs is 320. what would you tell the lawyer?

u i forgot the answer?

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.

hope this .
