What happens when a glass rod is rubbed with wool?

Explanation

**Step-by-Step Solution:**

1. **Understanding the Materials**: We start with a glass rod and wool. These two materials are commonly used in experiments involving static electricity.

2. **Rubbing the Glass Rod with Wool**: When the glass rod is rubbed with wool, friction occurs between the two materials. This friction is crucial for the transfer of electrons.

3. **Electron Movement**: The glass rod has a tendency to lose electrons when rubbed. This means that the electrons from the glass rod are transferred to the wool.
