A tube is placed in a cylinder filled with water. A tuning fork is struck and brought near the tube. The tube is moved up out of the water until a sound is heard in the tube. The steps are repeated using tuning forks that produce different frequencies, and the length of tube above the water is recorded each time in a table.

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 .
