The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension. With Surface tension molecules at the surface do not have other like molecules on all sides of them and consequently they cohere more strongly to those directly associated with them on the surface. This forms a surface with a type of film barrier that makes it more difficult to move an object through the surface than to move it when …

…and re form. The "life expectancy" of one hydrogen bond is about a few trillionths of a second. Cohesion plays an important factor in the growth and continued like of trees. Cohesion allows organisms at the very top of a tree to obtain nutrients through all of the water molecules sticking together as they make their way up through the trees small xylem vessels. Adhesion helps the water to resist the downward pull of gravity.
