How is surface tension created in water

WebWhat is surface tension. Surface tension is defined as the work, dW, required to expand a surface by dA. It is, thus, a direct measure of the energy needed to form a new surface of unit area, i.e. surface energy. Surface tension is a characteristic of any surface or interface, however, it is only directly measurable for liquids. Web3 apr. 2024 · There is a common definition of wetting the surface. If the angle of the contact between three materials is larger than 90° then it is non–wetting. On the other hand, if the angle is below than 90° the material is wetting the surface (see Fig. 1.22). The angle is determined by properties of the liquid, gas medium and the solid surface.
