液体的滴数问题是化学实验等实际工作中经常遇到的界面问题。液滴体积与液体的表面张力有关,因此一定体积的液体所具有的液滴数也与表面张力有关。但若仅考虑表面张力的影响而忽视密度的作用,则有可能得出不正确的结论。本文从一道考题入手,讨论了表面张力、密度等因素对液滴大小的影响,对考题答案进行了分析。 The problem of the number of drops of liquid is often encountered in the actual work of chemical experiments and other interface problems. The volume of a droplet is related to the surface tension of the liquid, so the volume of liquid that a given volume of liquid also has depends on the surface tension. However, if only the effect of surface tension is ignored and the effect of density is neglected, it is possible to draw incorrect conclusions. This article starts with a test questions, discusses the surface tension, density and other factors on the size of the drop, the answer to the test questions were analyzed.
