WebThe surface tension of water provides the necessary wall tension for the formation of bubbles with water. The tendency to minimize that wall tension pulls the bubbles into … WebThe soap bubbles in this photograph are caused by cohesive forces among molecules in liquids. (credit: Steve Ford Elliott) ... Figure 3 shows one way to measure surface tension. The liquid film exerts a force on the movable wire in an attempt to reduce its surface area. The magnitude of this force depends on the surface tension of the liquid ...

WebB ecause the greasy end of the soap molecule sticks out from the surface of the bubble, the soap film is somewhat protected from evaporation (grease doesn't evaporate) which prolongs the life of the bubble substantially. A closed container saturated with water vapor (as in the Exploratorium "Soap Film" exhibit) also slows evaporation and allows soap films …

And when you wash your hands, when we use detergents. If you washed your hands with just regular water and that's it, sometimes the surface tension's too great. These water molecules are too bound to each other. They form too big of a clump. It doesn't look like it.
WebIf the surface tension of soapy water is 0.0260 N/m, how much force does the soap film exert on the 0.600 m side? A) 3.12x10^-3 N B) 1.56x10^-3 N C) 6.24x10^-3 N D) none of the above I'm really looking for the correct formula to use to solve this equation. Thank you.
WebL for which the film breaks. Ignoring gravity, the only force acting on a patch of the soap film is surface tension, which acts to minimize the area of the entire film (because surface tension is the elastic potential energy per unit surface area).
