This is accompanied by a decrease of the water surface tension from 72 to 24 mJ·m −2 . A strain lacking SC3 (ΔSC3) reduces the surface tension less dramatically and therefore forms only a few aerial hyphae [19,25]. Hyphae that grow …
WebAug 10, 2024 · The "salt" end of the soap molecule is ionic and hydrophilic (water soluble). Examples of soap and detergent molecules, are shown in Figure \(\PageIndex{4}\). The use of such compounds as cleaning agents is facilitated by their surfactant character, which lowers the surface tension of water, allowing it to penetrate and wet a variety of materials.

WebSep 3, 2015 · The polar end of the surfactant is attracted to the polar water molecule. When enough surfactant molecules attach to a water molecule, it gets covered in surfactant and forms a unit. These units have a weaker force of attraction because only the non polar head of the surfactant is exposed thereby lowering the surface tension. WebTable 11.3 lists values of γ γ for some liquids. For the insect of Figure 11.25(a), its weight w w is supported by the upward components of the surface tension force: w = γL sin θ w = γL sin θ, where L L is the circumference of the insect’s foot in contact with the water. Figure 11.26 shows one way to measure surface tension. The liquid film exerts a force on the …
