Some Examples Explaining Surface Tension and Surface Energy. 13/05/2013В В· They donвЂ™t like to stick to the air as much as they like to stick to each other. This creates surface tension, which means that the surface of the water acts like a kind of skin or trampoline for very small objects. Some very small objects can rest on the surface of the water as long as theyвЂ™re small enough to not break the surface tension., It sinks because the surface tension is reduced by the detergent. Currents are set up in the milk which causes the food coloring to mix. A cylinder of water is lifted from the petri dish. A drop of detergent would dramatically reduce the surface tension so no visible amount of the solution could be lifted..

Surface tension is an important property of the surface of a liquid. It is what causes the surface of a portion of liquid to be attracted by another surface, such as that of another portion of liquid. Usually, the higher the surface tension is, the stronger the interactions between the molecules of the liquid are. The surface tension decreases Surface tension is a physical property equal to the amount of force per unit area necessary to expand the surface of a liquid. It is the tendency of a fluid surface to occupy the smallest possible surface area. Surface tension is a principal factor in capillary action. The addition of substances called surfactants can reduce the surface tension
