Why are the three different surface tensions in the directions shown?

[QUOTE="Lnewqban, post: 6825145, member: 673625"] Your understanding seems correct to me. The diagram of forces is for one molecule of liquid located in the peripherical line and which is simultaneously in close contact with molecules of air and molecules of solid. Please, see: [URL]https://courses.lumenlearning.com/atd-austincc-physics1/chapter/11-8-cohesion-and-adhesion-in-liquids-surface-tension-and-capillary-action/[/URL] [URL]https://media.eurekalert.org/multimedia_prod/pub/web/141315_web.jpg[/URL] [URL]https://en.m.wikipedia.org/wiki/Contact_angle[/URL] The adhesive force between the solid surface and the liquid causes the drop to spread and wet the surface, and the cohesive force within the liquid drop causes it to try to adopt the shape of a sphere and avoid contact with the surface.
