You will get to learn about the different states of matter and the nature of physical properties. Explore how the properties of matter are related to size.
After completing this tutorial, you will be able to complete the following:
Why is plasma accepted as the fourth state of matter?
~ Plasma is accepted as the fourth state of matter because it consists of highly energized masses of gas that contain free-moving electrons that are partially or completely ionized. Therefore, plasma has different electromagnetic properties than the other states of matter.
What are some examples of hot plasma?
~ Lightning, the sun, stars, and fire are examples of hot plasma.
What are some examples of cold plasma?
~ The Northern Lights, neon lamps, fluorescent bulbs, and some television screens are examples of cold plasma.
How might plasma be used in the future?
~ Plasma might be used as a source of clean energy in power plants in the future. Research into plasma at varying temperatures continues.
