Plasma (physics)

The video explains the concept of ions, which are electrically charged particles. It highlights how these ions contribute to electrical conductivity and responsiveness to magnetic fields. The video also provides examples of plasma, such as stars and the glowing gas in fluorescent lights.

What are ions?

• Neutral particles

• Particles with no charge

• Electrically charged particles

• Magnetic particles

How do ions affect a material's properties?

• They make it heavier

• They make it electrically conductive

• They make it less dense

• They make it transparent

What is one characteristic of materials with ions?

• They are highly responsive to magnetic fields

• They are always liquid

• They are always solid

• They are non-responsive to magnetic fields

Which of the following is an example of plasma?

• A wooden table

• A glass of water

• A glowing gas in fluorescent lights

• A solid rock

What celestial body is an example of plasma?

• A planet

• A star
