WebDec 6, 2024 · Surface tension is the energy required to increase the surface area of a liquid by a unit amount and varies greatly from liquid to liquid based on the nature of the intermolecular forces, e.g., water with hydrogen bonds has a surface tension of 7.29 x 10-2 J/m 2 (at 20°C), while mercury with metallic bonds has as surface tension that is 15 ...

WebCohesive forces between like molecules are responsible for a liquid’s viscosity (resistance to flow) and surface tension (elasticity of a liquid surface). Adhesive forces between the molecules of a liquid and different molecules composing a surface in contact with the liquid are responsible for phenomena such as surface wetting and capillary rise. WebHowever, surface-based cohesive behavior is typically easier to define and allows simulation of a wider range of cohesive interactions, such as two “sticky” surfaces coming into contact during an analysis. Surface-based cohesive behavior is primarily intended for situations in which the interface thickness is negligibly small.
