Cohesion
Cohesion is a fundamental concept in chemistry and physics that describes the strong binding forces between atoms or molecules within a particular substance. These forces are responsible for the cohesion and stability of the material.
An important effect of cohesion is surface tension, which causes liquids such as water to adopt a tendency towards a spherical shape and to form droplets. This surface tension is the result of the cohesive forces between the molecules at the surface of the liquid.
In addition, cohesion also plays a decisive role in solids, where it is responsible for the structural stability and strength of the material. It enables the atoms or molecules to bind closely to one another and thus form a solid, coherent body.
