Learn the basics about plasma – the fourth state of matter, when learning about properties of matter.

When ice is sufficiently heated, it melts to form water. It has therefore undergone a change of state – from a solid to a liquid. Recall that in a solid, all of the particles are closely packed in a fixed position, and therefore has a fixed shape and volume. The particles in a liquid are still touching one another and are able to move around one another, therefore, a liquid still has a fixed volume but takes the shape of their container.

Water evaporates from a liquid to a gas. The particles in a gas are further away from one another and take the shape and volume of their container. For certain substances, if we continue to apply heat to their gaseous form, another change of state could occur. These substances can go from a gas to a state of matter called plasma. For this change of state to occur, very strong heat must be applied. When heat is sufficiently strong, the electrons are stripped from their respective atoms, creating free electrons and positive ions. Although there are both negative and positive particles, overall, plasma is neutral as there are equal amounts of oppositely charged particles. Because there are free electrons, substances in a plasma form can conduct electricity.

This is what separates a gas from plasma – gases cannot conduct electricity, but plasma can.

Naturally occurring plasma include lightning and the Northern lights. Stars also exist in plasma form – in fact stars are just really hot balls of plasma. Plasma can be found in fluorescent light bulbs and neon signs.

When an electrical current is passed through the mercury vapour in fluorescent light bulbs and certain noble gases in neon signs, it heats up the gases sufficiently to strip the electrons and create plasma. The technology actually goes even further beyond light bulbs and neon signs. Plasma screen TVs are made possible due to this state of matter. A plasma screen is made of many thousands of tiny dots called pixels, which are made of three fluorescent light electrodes, emitting the colours red, green, and blue. The combination of these colours can give any possible colour, which is why we can see all colours on these screens.

The higher the number of pixels, the higher the definition, and the images will appear “sharper” and more detailed.

  1. Thanks for the video I have questions.
    1. If I understood this right the color emitted by the plasma is due to the electrons and ions seperating causing a photon to emit. Is this right? I am a bit confused because in another video I saw that the glow is due to the short lifetime of excited species.
    2. Does making plasma require a lot of voltage?

  2. Jai Shree Ram🙏🙏🙏🙏🚩🚩🚩🚩🚩

  3. Does it mean at the state of plasma atom generate photons ????

  4. Sooo it..a like a gelatin basically is the best way to simplify this for the simpletons?

  5. 🤔🤔🤔🤔🧐🤯think about it stars

  6. me who knows there are 50 more states such as new york Alabama Florida etc

  7. There's actually seven (as of 13th July 2021), not four. Crazy I know, but scientists can't help making stuff up….

  8. Does the amount of water heated changes the amount of plasma you get I'm 11 years old

  9. Very informative video, explained in a very simple and beautiful way…hope our teachers adopt this style of explanation

  10. Thank you so much…. Amazing explanation ☺🤗👍👍👍👍

  11. Evaporation is completely different to boiling, water in a swimming pool can evaporate on a hot day. The odds on it boiling are very slim without a massive amount of fuel.

  12. you are such a great teacher your explanation style is too good to keep it up great effort

  13. It is very useful for my class thank you 😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎😎

  14. Do photons in plasma stay with the plasma like a line with small balls on it? It would explain how the Tokamak makes plasma without getting burned from the inside.

  15. this means that atars are electric they are glowing plasma not nuclear

  16. Remember when videos like this was what YouTube was about?

  17. Explaind v welll….. Easy to understand…. Thanks mam

  18. i like how the narrator says "in a previous episode" even though its been two years

  19. Why does it say you cannot squash a solid? Of course you can.

  20. So basically gas that can conduct electricity?

    I noticed in the video, it was implied that some gases can conduct electricity. Whatis the difference between plasmas and conductive gases?

  21. Its rather suspicious that it's only being taught this past decade ! Also I noticed that she conveniently forgot about our own sun.

  22. Then What will happen if you cold gas or more heat to plasma?🤔

  23. Now we need to learn about the 5th state of matter the Bose-Einstein Condensate

  24. This is the best video about plasma definition & explanation.
