What happens when you blow bubbles at a van de graaf, and why does that happen? I know that the bubbles will repel once they get closer, but why?
The repulsion of bubbles in a Van De Graaf generator is due to the build-up of static electricity on the surface of the bubbles. As the generator creates a high voltage, the bubbles become negatively charged and repel each other due to their like charges.
The shape of the bubbles does not have a significant impact on their repulsion in a Van De Graaf generator. As long as the bubbles are spherical and contain air, the repulsion will occur due to the build-up of static electricity.
Yes, different types of gases can be used to create bubbles in a Van De Graaf generator. However, the bubbles will only repel each other if they contain air, as air contains charged particles that allow for the build-up of static electricity.
There is no specific limit to the number of bubbles that can be generated in a Van De Graaf generator. However, the size of the generator and the amount of voltage being produced may affect the number of bubbles that can be created.
The repulsion of bubbles in a Van De Graaf generator is mainly used for demonstration purposes. However, the principle of static electricity and repulsion can be applied in various technologies, such as electrostatic precipitators used in air pollution control.
