Cohesion occurs when molecules of the same substance attract one another. This property is demonstrated when water molecules cling to one another and form beads on smooth surfaces. Adhesion is when molecules of a substance cling to molecules of a different substance. This occurs when molecules of water cling to the inner surface of a graduated cylinder, causing a shallow dip at the center of the water's surface.
