Surface tension of water in contact with air

WebJan 30, 2024 · What would be the height of a liquid in a column, on earth, with a liquid-air surface tension 0f .0973 N/m, contact angle of 30 degrees, density of 1200 kg/m 3? Note that the radius of the tube is 0.2 meters. What would be the height of water in a glass tube with a radius of .6mm? Solutions WebIf water gets into the lungs, the surface tension is too great and you cannot inhale. This is a severe problem in resuscitating drowning victims. A similar problem occurs in newborn infants who are born without this surfactant—their lungs are very difficult to inflate.

WebSo, surface tension is due to cohesion between the water molecules at the surface of a liquid, but water molecules aren't just attracted to each other. They're actually attracted to the container too and other materials, and that's called adhesion. So, the fact that water molecules are attracted to other materials as well is called adhesion. WebJun 6, 2024 · Surface tension could be defined as the property of the surface of a liquid that allows it to resist an external force, due to the cohesive nature of the water molecules. …

WebSep 3, 2015 · If you increase the concentration of surfactant, they start to form micelles in the water (and not on the surface). So after reaching this critical micelle concentration (called CMC) the surface tension stays quite constant. This constant behaviour is used experimentally to estimate the CMC.
