ETYM Cf. French cohésion. Related to Cohere.
The intermolecular force that holds together the molecules in a solid or liquid.
Molecular attraction which holds two particles together.
Force uniting parts; interdependence.
In physics, a phenomenon in which interaction between two surfaces of the same material in contact makes them cling together (with two different materials the similar phenomenon is called adhesion). According to kinetic theory, cohesion is caused by attraction between particles at the atomic or molecular level. Surface tension, which causes liquids to form spherical droplets, is caused by cohesion.
