Answer:

When silk is rubbed on a glass rod, an electrostatic charge is generated in a phenomenon known as the triboelectric effect. It is this electric charge that gives you a shock in winter when your rubber-soled shoes rub against a carpeted floor. The triboelectric series is a list of materials sorted according to their electrostatic behavior; using the list, you can predict the electrostatic effects when silk is rubbed on a glass rod.
