The Electrostatic Series You can use a list called the electrostatic series to determine the kind of electric charge produced on each substance when only two substances on the list are rubbed together. When charging by friction occurs, the substance higher on the list always loses electrons (it does not have a strong hold on its electrons) and becomes positively charged and the substance lower in the list gains those electrons and becomes negatively charged.                 

Using the electrostatic series, answer the following questions: 1. Predict what will happen when rubber is rubbed with cotton. ______________________________ ________________________________________________________________________________ 2.

Explain what happens when wool is moved over silk. ______________________________________ _________________________________________________________________________________

3. What charge does ebonite have once it has been rubbed with fur? ___________________________ 4. If you wanted a rubber balloon to have a positive charge what material could you rub against it? __________________________________________________________________________________ 5. When plastic adhesive tape that is stuck to glass is quickly pulled away, it becomes negatively charged. a. Explain what happened to the glass in terms of electrons. ___________________________ ___________________________________________________________________________ 6. Explain why clothes cling to each other after tumbling around in a clothes dryer.________________ _____________________________________________________________________________________ _____________________________________________________________________________________...
