Critical surface tension Advancing your Surface Science
Using the Young-Laplace Equation (if applicable), find the surface tension (dynes/cm) for water at 20 degrees Celsius with 2.5 psi. Round to the nearest tenth. Round to the nearest tenth. Well, I didn't use the Young-Laplace equation, not sure if needed though.... approach one can calculate the surface tension of water/surfactant solution as a function of surfactant surface concentration, Γ. This method predicts the correct qualitative dependence σ(Г) and reproduces other important trends. However, the direct application of this approach to calculation of σcmc would be challenging as it would involve the calculation or measurement of the surface

Detergent molecules have a very clever property, with one end hydrophilic, or water-loving, and the other hydrophobic, or repelled by water. This dual nature allows detergent to reduce the surface tension …...
The third method also allows the calculation of the surface tension between a solid spherical nanoparticle and a liquid, which makes a direct link to the motivating example given above.

How To Find Surface Tension

The third method also allows the calculation of the surface tension between a solid spherical nanoparticle and a liquid, which makes a direct link to the motivating example given above.

  • Surface tension is the cohesive force of molecules at the surface of an element attracting toward one another to take up the least possible surface area. In even simpler terms, it measures how much force it takes to keep a liquid together.
  • approach one can calculate the surface tension of water/surfactant solution as a function of surfactant surface concentration, Γ. This method predicts the correct qualitative dependence σ(Г) and reproduces other important trends. However, the direct application of this approach to calculation of σcmc would be challenging as it would involve the calculation or measurement of the surface
  • Any object that 'floats' on a liquid surface has a static equilibrium between the downward body force (due to downward pull of gravity), a buoyant force due to the displacement of liquid volume by the body, and a surface tension force in the direction of the contact angle (the meniscus angle).
  • Class practical. A fine insoluble powder, such as talcum powder, is sprinkled on a clean water surface in a beaker, a drop of detergent or soap solution added to the centre, and the effect observed as the surface tension of the water is changed.
