| Nov 13, 2020 at 15:44 | comment | added | Jon Custer | Because for the thought process you start with a situation where there is no surface at all, and then introduce one to see what the surface brings to the situation. Since it takes energy to form the surface, it is clear that objects with surfaces will want to minimize their surface area to minimize that area. | |

| Nov 13, 2020 at 15:41 | comment | added | Jon Custer | Because if you start with an infinite solid and cut it in half, it takes energy to break all the bonds. You are left with a bunch of atoms on the surface that are unhappy since their bonds are not fully satisfied (and to make them unsatisfied in the first place took energy). | |
