a: graphite molecular structure ~
b: deck of cards
What:
This is why graphite is such a good lubricant. At the molecular level, the molecules are planar(playing card like). The flatness produces a molecular structure that allows the graphite molecules to slide across each other with minimal input of energy. If you pick up a deck of cards, the whole deck with slide, because their shape allows each individual card to slide against its neighbor with little friction.
