... 4. In beaker (B) - Dipole-dipole forces act between molecules possessing permanent dipoles. Ends of dipoles possess partial positive and negative charges which account for electrostatic forces of attraction and hence dipole-dipole forces. We can guess that if a molecule is polar then mostly it is bo ...

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.
