It turns out that this surface tension is the result of the tendency of water molecules to attract one another. For example, if you place a capillary glass tube open ended into a container with water, you will observe a concave up curve as a result of water molecules attracted to the polar glass capillary tube.
Structural Biochemistry. The water drop is stuck to the end of the pine needles, which is an example of the property of adhesion. These ingredients are pulverized, and made into a cohesive paste with the gum.
It is lucky for the drops that adhesion is holding them, at least for now, to the pine needle. View full size I used to wake up in a cold sweat in the middle of the night because I could not get the concepts of water adhesion and cohesion clear in my mind.

Water is attracted to water Adhesion: Water is attracted to other substances. Jane Harman June 14, 2013.
My Religion Leo Tolstoy. Tuesday, 17-Jul-2018 07: Water is attracted to other substances Adhesion and cohesion are water properties that affect every water molecule on earth and also the interaction of water molecules with molecules of other substances.
In a water molecule, the two hydrogen atoms align themselves along one side of the oxygen atom, with the result being that the oxygen side has a slight negative charge and the side with the hydrogen atoms has a slight positive charge. As shown in the figured.
Frank Merriwell's Triumph Burt L. Water is highly cohesive—it is the highest of the non-metallic liquids. Geological Survey URL: The ability of some insects to float on water is accounted for because of this property.
J Schmidt; National Park Service. Thus when the positive side on one water molecule comes near the negative side of another water molecule, they attract each other and form a bond. United, cohesive cooperation is the source of irresistible strength. This page was last edited on 24 February 2015, at 09: Cohesion and adhesion in water are caused by the intermolecular attraction between the partial negative oxygen of one water molecule, and the partial positive hydrogen of another molecule.
