The action of rubbing a balloon on our head explains the law of Charge Conservation.

Here's the step by step explanation:

1. When you rub a balloon on your hair, electrons (which carry a negative charge) are transferred from your hair to the balloon. This is due to the difference in the materials' ability to attract electrons, a property known as electronegativity.

2. After the rubbing, the balloon has gained extra electrons from your hair, making it negatively charged. Your hair, having lost electrons, becomes positively charged.

3. If you bring the balloon close to your hair, your hair will be attracted to the balloon. This is because opposite charges attract each other, according to the law of electrostatics.

4. The total amount of charge, however, remains constant. The electrons have simply moved from one place to another. This is the principle of Charge Conservation. The law of Charge Conservation states that the total charge in an isolated system remains constant.
