Surface tension results from the inward pull of molecules on the surface of a liquid, making them adopt the smallest surface area possible. It effectively makes the surface stronger, allowing a small object such as a sewing needle to effectively 'float' on water, even though the object may be...

Surface tension of any fluid is crucial for multiphase systems and is often manipulated during industrial processes by introducing surfactants. Normally, water used in an industry includes impurity such as salt. In this study, effect of salt kinds and concentrations on surface tension of water was ...
Clotting is efficient because of the high value ofsurface tensionof water. 由于水的表面张力很高,血液得以凝固. 期刊摘选 Surface tensionis one of the important control parameters of the ceramic squeegee oil. 表面张力的控制是陶瓷印油产品的主要控制指标之一. ...
surface tension, property of aliquidsurfacedisplayed by its acting as if it were a stretched elastic membrane. This phenomenon can be observed in the nearly spherical shape of small drops of liquids and of soap bubbles. Because of this property, certaininsectscan stand on the surface ofwater. ...

The meaning of SURFACE TENSION is the attractive force exerted upon the surface molecules of a liquid by the molecules beneath that tends to draw the surface molecules into the bulk of the liquid and makes the liquid assume the shape having the least sur
It has been reported that an oil droplet on a glass surface moves spontaneously in an oil-water system. This motion of an oil droplet can be understood as the spreading of a reactive droplet, which is induced by the interfacial tension g... Y Sumino,N Magome,K Yoshikawa - 《Progress of...
aThe test report was brief - unit was flooded and PCBs shorted out and corroded. The extent of corrosion indicates that the water was underwater for more than 30 minutes. We have never had a unit that was subjected to a rain storm fill up with water like this. 实验报告是简要的-单位被...
