Isabella is researching how to charge objects through friction. Isabella rubs a balloon on her hair. When she pulls the balloon away from her hair, the hair is attracted to the balloon. Which BEST explains why the hair becomes attracted to the balloon?

A. Rubbing the balloon along her hair creates protons that will stick to both the balloon and her hair.
B. Rubbing the balloon along her hair moves protons from the balloon to her hair.
C. Rubbing the balloon along her hair moves electrons from her hair to the balloon.
D. Rubbing the balloon along her hair creates electrons that will stick to both the balloon and her hair.
C. Rubbing the balloon along her hair moves electrons from her hair to the balloon.
C. Rubbing the balloon along her hair moves electrons from her hair to the balloon.
This phenomenon is known as the triboelectric effect, which involves the transfer of electrons between two different materials when they rub against each other. In this case, when Isabella rubs the balloon against her hair, electrons are transferred from her hair to the balloon. This causes the balloon to become negatively charged, while her hair becomes positively charged.
Since opposite charges attract each other, the positively charged hair is attracted to the negatively charged balloon, leading to the observed attraction.
