Why does low-surface-tension-liquids-clean-better than high-surface-tension-liquids?
Low surface tension means high wetting as it represents low contact angle. It is therefore very easy for a low surface tension water / liquid to wet the surface ( usually solid) and get rid of the dirty in a same way a surfactant does unlike a high surface tension liquid which can't wett the surface containing the dirty....

What makes water have surface tension?
Surface tension is The attraction of molecules to each other on a liquid's surface? Surface tension of water is the physical property of hydrogen bonding that makes the water molecule. The way that this works is that a water molecule (H2O) is a polar molecule. This is because the oxygen has a much higher electronegative value than the hydrogen. This means that the oxygen gets a lot higher 'share' of the shared electrons than the hydrogen does. This gives oxygen a very high partialnegative charge, and the hydrogen a very high partial positive charge. Because of these high partial charges on each end of the molecule, they are very highly attracted to each other
Do crystalline solids have high surface tension?
It does not. Surface tension of a liquid exists due to the fact that the molecules are at a higher potential when they are at the surface than when they are submerged in the bulk. A liquid system then tends to minimize its total free energy in such a way that the surface molecules, given the opportunity, "dive". Other surface molecules must replace a diving molecule on the surface and this makes the surface shrink laterally. Correspondingly, when the surface is stretched, molecules that have a smaller potential in the bulk are lifted to the surface so that work must be done and a force is required to do the stretching. On a solid, the molecules are constrained so that they cannot move freely. Hence, they cannot "dive". For the same reason they do not move laterally and there is no mechanism that could transfer the potential difference in the direction perpendicular to a surface into actions parallel to it. In capillary processes it often appears as if a solid would have a surface tension. Many phenomena can be nicely explained that way, but this is only because there are forces acting between a solid and a liquid, and it is the liquid that is able to adjust to them. In physics literature you would find "Shuttleworth's equation" relating the surface tension with the surface energy on a solid. This, however, has recently been shown to be incorrect (Surface Science, 603(1): 97-101. LM
How does surface tension force the water surface of water to curve?
Gravity and surface tension forces on the water causing water to curve.
Why do iron filings do not sink when placed slowly on the surface of the water?
Surface tension supports the filings in the same way as a pond skater. Add a drop of detergent and the meniscus is broken down and the filings fall to the bottom
Do you leave the shell on the egg before you put vinegar on it to make it a bouncy egg?
Yes. The vinegar helps dissolve the shell surface, giving way to the membrane underneath that makes the egg "bouncy."
How does a needle float on water?
the way it float is surface tension!!
How can a mosquito walk on water?
There are several insects that can walk on water due to the water's surface tension. There are over 300 species of water striders that are able to walk on water, as well as several species of ant.

Is there a way to increase the surface tension of water?
The surface tension of "pure" water against air at 20 degrees C is 72.75 dynes/cm. This increases with cooling and decreases with heating. Most inorganic solutes increase the surface tension of the solution when dissolved in water. Most mineral acids decrease the surface tension of the solution in water (sulfuric acid is the most obvious exception). Most organic compounds decrease the surface tension of the solution in water (organic acids and alcohols are often exceptions). It is important to note that we are talking about increasing and decreasing the surface tensions of solutions of these things in water with respect to distilled water. In order to change the surface tension of distilled water, just changing the temperature will suffice. PS : At 0 degrees Celsius, the surface tension of water is 75.6 dynes/cm, at 100 degrees it is only 58.9 dynes/cm.

Surface tension.
Which has more surface tension clean water or soapy water?
Yes, pure water is a one molecule based structure, which hold together better than a mixture. When soap or other chemical is added, it breaks surface tension by getting in the way of each water molecule. Try putting water drops on a penny to build a bubble, then add a small drop of soap to it, you'll see that when soap is added, the water bubble collapses.
Why needle sinks in water and thread does not even both has equal surface areas?
Actually, its the other way around. A needle will float on water due to surface tension of the water. Thread will not because the fibers of the thread will break the bonds of the surface tension and allow the thread to sink. Also, the thread is not straight as is the needle.
