If a liquid sample of naphthalene is heated and remains at 218 degrees c until it is completely vaporized, you know that 218 degrees c is the of naphthalene

a) freezing point

b) boiling point

c) melting point

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 .

the answer is barium and copper bromide
