ytansvärde
Ytansvärde is a term used in chemistry and materials science to describe the energy required to create a unit area of new surface. It is often expressed in units of joules per square meter (J/m²) or ergs per square centimeter (erg/cm²). This property is a manifestation of the cohesive forces between molecules or atoms within a substance. Atoms or molecules at the surface experience fewer attractive forces from neighboring particles compared to those in the bulk of the material. This imbalance leads to an excess of energy at the surface, which the system tends to minimize.
Surface tension, a related concept, is the force acting per unit length at the interface between two
