Every substance contains molecules that have a positive or negative charge. When the glue dries over a surface, it hardens, causing the molecules to stick together.
Why do perfectly flat surfaces stick together?
The source of the forces holding gage blocks together are thought to come from: Molecular force caused by the interchange of electrons between the atoms of the separate blocks when two very flat surfaces are brought into such close contact with each other.
What is it called when 2 surfaces meet?
In geometry, a vertex (in plural form: vertices or vertexes), often denoted by letters such as , , , , is a point where two or more curves, lines, or edges meet. As a consequence of this definition, the point where two lines meet to form an angle and the corners of polygons and polyhedra are vertices.
