SPLATS about surface tension
The principles of surface tension
- Surface tension gives rise to capillary action and this explains why water will soak into a rock, and many other effects, including 'wetting'.
- Surface tension affects many animals, but it usually has a greater effect on small animals which encounter greater pro rata forces on their smaller mass.
- Surface tension effects give rise to the meniscus at a liquid boundary, the curve being shaped by the relative attractions of the molecules for each other.
- Two-dimensional bubble films will always contract and take up a shape to minimize their surface areas in the same way that a three-dimensional bubble does.
- The pressure inside the bubble is greater than the pressure outside, due to the compressive effects of surface tension in the bubble on the air inside.
- Bubbles take the shape which minimizes their surface area: when they are unconstrained, this will normally be a sphere, but other shapes are possible.
