The contact angle a liquid drop makes with a solid surface is a function of the surface energies of the liquid, solid, and liquid-solid interface. This relationship is described by the Young equation.

Not very convincing, yet clear explanation. Why do the the surfance tension vectors (or surface forces) point in those directions? (min 4:46)Thanks a lot for this video.
@schaz75635 жыл бұрын
Creation of any surface (a boundary between two media) generally results in a higher potential. All the forces point in their respective directions to minimize the surface areas of the boundary they are associated with.

@@schaz7563 Hi, could you expand on this further please? The one that confuses me is the surface tension of solid and vapour. Why does that point to the left? I do not understand why there is a force between the solid and vapour pointing to the left. If you could explain that it would be great, thanks.
