| Applications of Surface Tension |
|
 Surface tension of soap solution is less, it can spread over large areas and wash clothes more effectively, since the dirt particles stick to the soap molecules. |
| |
| In soldering, addition of flux reduces the surface tension of molten tin. Hence, it spreads. |
| |
 Antiseptics like dettol have low surface tension, so that they spread faster. |
| |
 Surface tension prevents water from passing through the pores of an umbrella. |
| |
 A duck is able to float on water as its feathers secrete oil that lowers the surface tension of water. |
