What is the Difference Between Blended Learning & Distance Learning? Services. In the adsorption mechanism, adhesion is modeled as occurring across a well-defined interface by molecular interaction across that interface, and is often referred to as ‘contact adhesion’. It comes from the root words “ad” for “other” and “hesion” for “to stick to.” Adhesion is usually caused by interactions between the molecules of the two substances. credit by exam that is accepted by over 1,500 colleges and universities. Metastatic cancer cells have reduced adhesive properties.

In a covalent bond, the electrons of the bonded atoms are shared. Already registered? It can be measured in terms of work of adhesion in J/m 2. Because atoms of opposite charges are actively attracted to each other, different parts of water molecules are attracted to both positive and negative ions and molecules. Thus, without adhesion and capillary action, plants would not be able to properly distribute their water.
