Document Summary
Adhesion: the adherence of molecules to the walls of conducting tubes, as in plants. Adhesion is the tendency of dissimilar particles and/or surfaces to cling to one another (cohesion refers to the tendency of similar or identical particles/surfaces to cling to one another). The forces that cause adhesion and cohesion can be divided into several different types. The intermolecular forces responsible for the function of various kinds of stickers and sticky tape fall into the categories of chemical adhesion, dispersive adhesion, and diffusive adhesion. In addition to the cumulative magnitudes of these intermolecular forces, there are certain emergent mechanical effects that will also be discussed at the end of the article. Archaean eon: one of two domains of prokaryotes; archaeans have some unique molecular and biochemical traits, but they also share some traits with bacteria and other traits with eukarya.
