Cohesion comes from the Latin "cohaesum, supino de cohaerēre, to be united", this refers to the force between the particles that hold the parts of a substance together, the cohesion is diverse to the adhesion by the energy of the uptake between the contiguous parts within of the same body as opposed to adhesion which is the reciprocal action, relationship or influence between two or more entities or things on the surfaces of different bodies.
In water, the cohesion energy is high due to the hydrogen bonds that are chemical elements with symbol H and atomic number 1; which is a colorless gas and lighter than air, which enters the combination of many organic substances and a large number of inorganic substances, combined with oxygen, but also forms water that holds the water particles tightly together, forming a organization that compacts and changes it into a liquid that is applied to the body that cannot be compressed, but since it cannot be compressed, it can act as a hydrostatic skeleton in some animals which is relative to the equilibrium of the gas glasses and the bodies that float in them, as well as it can happen in some boring worms capable of opening the rock due to the pressure generated by its internal liquids.
In this area you can find various types of cohesion such as terrain cohesion, social cohesion, textual cohesion, cohesion force.
Cohesion of the terrain, is the property by which the molecules of the terrain are held together by virtue of internal forces that are needed, among other things, from the number of contact points that each particle has with its inhabitants.
Social cohesion, in sociology is the degree of consensus that is an agreement between two or more entities around a subject where the members of a social group or the perception of belonging to a common project or situation that is a measure of intensity where the Social interaction within the group can be measured with a classification test or simply explained or defined for each case.

Cohesion force which are the forces that hold the particles together, but it is also the act or property of the particles of how they can stick together being forces of an attractive nature.
