1.Surface tension 1.1 How does surface tension generate? 通过很多现象(量筒度数、满水不溢)可以发现水像绷紧的膜一样。本点着重探究该现象的原因。 内容 定义:液体表面就像张开的橡胶膜一样,有一种收紧的趋势。这种使得液体表面收缩的力称之为表面张力。其来源是液体的内层分子作用 解析 ①简化水滴模型:想象一...

The rounded shape of water droplets on a surface is due to surface tension. Tears of wineform rivulets on the glass of an alcoholic beverage (not just wine) due to the interaction between the different surface tension values of ethanol and water and the faster evaporation of alcohol compared...
