When a small amount of pentane is in contact with a water droplet on top of a glass table, it forms a very thin film that covers the droplet and part of the table. Why does the pentane spread out and not form a droplet? Why does water form a droplet on glass (and not spread out)? Why do water and pentane not mix? How is the pentane able to "creep" up and across the water droplet to form a film? Please answer the questions by focusing on intermolecular forces.
