| Abstract: | The condition for the surface of a liquid drop forming spherical surface was induced by analysing three typical examples. It is that the difference between intra-surfacepressure and extra-surface pressure remains equal all over the surface.Jt was expounded byusing thermodynamics that the surface of a liquid drop with invariable volume must formspherical surface under this condition. |
