__//**How does graphite adhere to paper?**//__  Graphite is loosely bonded in layers to paper based on how much pressure is applied when a pencil presses on paper as a person is writing. This graphite adheres to the paper through a physical process called physisorption. Physisorption, or physical absorption, is a process in which an atom or molecule is barely is absorbed by another molecule, during which the electronic structure of said atom or molecule is barely if at all disturbed. This weak bonding is caused by the induced dipole moment that is created by nonpolar adsorbate interacting with its own image charge in the polarized solid. The Van der Waals Force makes this possible. These are relatively weak electric forces that attract neutral molecules to one another. This occurs in gases, liquefied and solidified gases, and in nearly all organic liquids and solids.

 * The pencil was invented more than 400 years ago, in 1565.
 * Famous novelists Ernest Hemingway and John Steinbeck used pencils to write their books.
 * Pencils didn't have erasers on them until 100 years ago because teachers felt they would encourage children to make mistakes.
 * It would cost $50 in labor and materials for a person to make a 10-cent pencil.
