... A. If a 3-D photocopier could replicate any three-dimensional object, it could change our lives in many positive ways. For example, it could eliminate waiting for delivery of items that need to be shipped from far away and it could replace lost or broken items. A 3-D photocopier could reproduce valu ...

... • In a nonpolar covalent bond, the atoms share the electron equally. • In a polar covalent bond, one atom is more electronegative, and the atoms share the electron unequally. • Unequal sharing of electrons causes a partial positive or negative charge for each atom or molecule. ...

Adhesion
Adhesion is the tendency of dissimilar particles or surfaces to cling to one another (cohesion refers to the tendency of similar or identical particles/surfaces to cling to one another). The forces that cause adhesion and cohesion can be divided into several types. The intermolecular forces responsible for the function of various kinds of stickers and sticky tape fall into the categories of chemical adhesion, dispersive adhesion, and diffusive adhesion. In addition to the cumulative magnitudes of these intermolecular forces, there are certain emergent mechanical effects that will also be discussed at the end of the article.
