WebDetailed Description. Water striders are able to walk on top of water due to a combination of several factors. Water striders use the high surface tension of water and long, hydrophobic legs to help them stay above water. Water striders use this surface tension to their advantage through their highly adapted legs and distributed weight. 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. WebWater has a high surface tension because the water molecules on the surface are pulled together by strong hydrogen bonds. That means a drop of water will "want" to have …
