Static Electricity – Part 2

The video tutorial explains static electricity using a balloon and demonstrates an experiment to show how charged balloons can affect a stream of water. It covers the materials needed, the polar nature of water, and provides a step-by-step guide to conducting the experiment safely.

What happens to the electrons on the surface of a balloon when it is rubbed against a shirt?

• They cause the balloon to deflate.

• They disappear from the balloon.

• They align along the surface, creating a static charge.

• They become positively charged.

Which of the following is NOT needed for the static electricity experiment?

• A lab coat

• A balloon

• A sweater

• A pinhole-free cup

What characteristic of water molecules allows them to interact with the charged balloon?

• Their ability to evaporate quickly

• Their high boiling point

• Their partial positive and negative charges

• Their non-polar nature

What is the purpose of adding food coloring to the water in the experiment?

• To change the water's chemical properties

• To make the water more conductive

• To make the water easier to see

• To increase the water's temperature

How can you tell that the water is being attracted to the balloon during the experiment?

• The water changes color.

• The water evaporates.

• The water stream bends towards the balloon.

• The water stops flowing.
