WebSurface effects (surface energy) play critical role many kinetics process of materials, such as the particle ripening and nucleation, as we will learn the lectures later. Typically, for many liquids and solid, surface energy (surface tension) is in the order of ~ 1 J/m2 (or N/m). For example, for water under ambient conditions, the surface WebSurface tension (denoted by σ ) describes the energy required to change the shape of a fluid when it comes into contact with another fluid in which it is not miscible (e.g., blood and air). This plays a big role in the formation of spherical blood droplets as they fall, as well as the way they react when they hit a surface. [19]
