@letter3able It serves 2 purposes: 1) it helps prevent heat loss, and 2) it also provides electrical shielding for some extremely sensitive diagnostics.

Easiest way to make plasma - light a match. Fire is plasma.
Easiest fun way to make plasma - cut a grape in half leaving some skin between the two halves connected and put in microwave, and don't forget to NOT DO THIS WITHOUT RESEARCHING IT FIRST.
@cookiemonster9052 A gas is never visible, and fire isn't a solid nor a liquid (for obvious reasons). So yes, fire is a plasma. Plasma is just a super-heated gas :)
@timoffex I think the answer is yes and no. Only if fire is hot enough, can it ionize into plasma. But fire is also just gasses reacting with each other to cause combustion. For instance, burning oxygen, it's still oxygen, but in a different state. So maybe you are right. I'll have to ask my chemistry teacher about this lol.
Hydrogen plasma is purple and the sun looks purple so the sun does have tons of hydrogen. I thought the electrons escape from the nuclei because the energy is so powerful. Plasma pistols will be powerful in the future.
First the glass pellet has to break. Then the plasma will burn and kill.
@neiallswheel Professor Oehrlein replies, "For the conditions discussed in the movie, that would not be the case. Good suggestion with the H2O vapor."
@bryanfuel Professor Oehrlein replies: "Yes--Lightning is an example. If you input enough energy into matter, then you can produce the plasma state in solids, liquids, or gases, including low-pressure gases. It really depends on what you want to do. We use a low pressure gas [in the lab] since it provides the most suitable environment for our applications."
@materialsatumd I have a question: plasma is heated hydrogen, right? If so, logically, what would happen if plasma was to say be dropped or projected inside of a hydrogen fuel cell?
@reptile202 Plasma can be made from a number of gases, not just hydrogen. Regarding the fuel cell question, we'll need to consult one of our fuel cell researchers. A side note: not all fuel cells need hydrogen--if you are interested, Google "solid oxide fuel cells" or see our Nov. 17 news story on the subject.
@materialsatumd Nov. 17 news story? Thanks for answering my question though. I'm just interest in the out-come of plasma coming into contact with hydrogen fuel.
My Teacher told me that the most common states were solid, liquid, and gas was she referring to earth because from what i learned about plasma is that stars fire lightning and so on is plasma I don't think she met the universe because plasma is super heated gas and the universe is made of that (execpt for earth and other planets.
@zJoWz Heat is created by individual atoms moving around quickly, correct? Enough heat will cause atoms to separate from eachother, and change into liquid or gas, correct? Enough heat will also cause the atom to separate into it's basic parts. Plasma is basically a gas that has been totally ionized due to heat.
@zJoWz Professor Oehrlein replies: "Energetic electrons colliding with atoms impart enough kinetic energy on electrons of the atoms so they become free, rather than bound (energy transfer is greater than ionization energy)."
@johnnyspermseed Professor Oehrlein replies, "Nitrogen is correct, but the plasma was not microwave, but RF. There were other gases in that example as well, including argon."
@powxpurplexx due to our current technology, we still lack the materials with extremely high melting points to store the gas and plasma and lack the power source to generate over 7000°C and make it portable enough as a weapon. Though even if we find the material with unmeltable quality, we can harvest plasma deep from our planets core.
@powxpurplexx Yes in theory but Plasma is extreemly difficult to control with current technology, so creating a plasma cannon would be quite an achievement to make.
@fLuFFyPuPPyS1 Yes Plasma is commonly found in stars, in fact a star is more or less one giant ball of plasma fueled by Thermonuclear Fusion. However it is possible to easily create plasma here on Earth, you just need the right amount of energy. Is is possible to create plasma arcs by diconnceting a high voltage circuit at temperatures over 20,000 degrees F.
@SASNIGHTCRAWLER Professor Oehrlein replies: "[You] are right about 'bose-einstein condensate'--it is a very cold state of matter, very close to 0 Kelvin."
@SASNIGHTCRAWLER We the editors will forward your question to him for you. Just a warning--we are at the start of finals here at the University of Maryland, so there may not be an immediate reply. on a related note, we appreciate those of you who have sometimes waited a while for answer. Between courses, research, advising, administrative matters, and travel, our faculty members are sometimes a little tricky to pin down! Thank you...we appreciate your interest.
@adiostraitorobama That is Prof. Oehrlein's lab website, which certainly has some good information about his work. re: the news, I was referring to our department's web site. Since we can't post a link, please try Googling "materials science university of maryland," then using our news search, searching on "Oehrlein," for the stories previously referred to. (These will provide a less technical introduction than the content of his lab site.)
@SASNIGHTCRAWLER Professor Oehrlein replies, "You are is approximately correct--it is in part due to the interaction of the charged particles with a magnetic field."
@raouldijksman Professor Oehrlein replies: "We did not intend to imply that there are only 4 states of matter. The reason plasma is referred to as the '4th state' is because it has been known as a separate state of matter for much longer--Bose and Einstein predicted the BEC state after plasma had been known as the 4th state."
@DragonxxxFire Fire isn't plasma unless it's ionized after reaching a much higher temperature. Otherwise, it's a mixture of gases and chemical reactions, obviously.
@KaeFive Most fire in the universe are on the stars, and stars are really hot, hotter than any fire on earth could be. So I'd still consider fire plasma.
@DragonxxxFire But we have the least exposure to stars, pretty much everyone sees them from millions of miles away and pretty much everyone experiences fire firsthand. It's like saying metal is a liquid. While it's possible, it's not practical to say it since it's less common, but still a changeable material. You shouldn't define it as one thing. If anything, you should say stars are plasma, since most people will think fire is burning wood.
The light emitted from plasma is due to electrons "jumping" in and out of orbit of the positive nucleus of the gas molocules. When the electron "falls" into orbit, it must lose energy, but to do so, it has to emit it, this radiated energy (electromagnetic radiation) is in the form of a photon, or visible light. This is why neon signs always have a single color, because the amount of energy an electron loses when falling into orbit is entirely dependent on the amount of energy needed to orbit.
so... are you talking about the atoms in the plasma diagram and gas diagram? or molecules or what? because i thought once electrons left their protons there was no element
@adiostraitorobama We really can't comment on Area 51 or UFOs, but if you visit our website (we can't put the link here; see our channel or Google) and go to News>Search News, and search on "Oehrlein," the stories about his sabbatical work on the design of future fusion reactors and plasma for disinfecting wounds and surgical equipment should give you an idea of the range of plasma temperatures and applications. Other stories describe his group's work using plasma in electronics manufacturing.
@adiostraitorobama Professor Gottlieb Oehrlein replies: "Supercooled is not a good term. It is low temperature as compared to hot. Plasma itself isn't used as fuel, but to transform energy from one state to another." To elaborate a little on the "supercooled" issue, it is not like supercooled water (water that doesn't freeze though it's below 32F or 0C). Prof. Oehrlein is conducting some research that utilizes plasma at approximately room temperature, and that is said to be "low temperature."
Professor Gottlieb Oehrlein replies: Blue light has a wavelength near 480 nm, which means that in a plasma gases that predominantly emit at that wavelength--such as the argon (Ar) used in the video--will appear bluish. However, the color of the emission is not just a property of the gas, but also depends on the electrical characteristics of the plasma.
Microwave, Glass Jar freshly burned (extinguished) match. Plasma in one atmosphere, I'll let you figure out the rest, WARNING: The plasma is very hot, may cause the jar to explode!
Technically a gas but it doesn't behave like either a gas or a liquid, all the molecules are rushing around each other mush faster than a normal gas, the inability to anthropomorphise it with any current state leads it to it's own classification.
wow thank you for explaning plasma i tryed watching another videos but lacked the atension or knowlege to under stand it the way you put may it much more simple to under stand
Very useful, helped me understand plasma (to a mild degree). Thanks for this video. I'm surprised at how common plasma has become. When was plasma first discovered, and is it naturally occuring?
@stephenB125 Thanks for your patience while we were closed for winter break. Sir William Crookes was one of the earliest (not necessarily the 1st but arguably the best known) people to describe and work with plasma in the mid-19th century, but the first person to use the term "plasma" was Irving Langmuir in the early 20th century. Yes, plasma is naturally occurring. Lightning, the Northern and Southern Lights, and stars are examples.
@smengel3 Professor Oehrlein replies: "The reason that Northern Lights are near the polar regions of the Earth is not because of the low temperature there, but because of the Earth's magnetic field. The latter traps charged particles, which collide with gas atoms and cause the emission."
@hardstyle905 I'm talking about a realistic plasma weapon. Yeah plasma weapons in games are unrealistic, the ones from Halo are patheticly weak when in reality they would blow a hole the size of a fist in it's target and cause it to combust, but that depends on the temperature and the amount of wattage it used.
@Yokailo The plasma processing team's equipment includes sealed chambers from which regular air is removed using a pump, creating the vacuum. Then, the chamber is refilled to a desired pressure with gas from a cylinder. Thanks for your interest in our video!
@boilingbubbles Professor Gottlieb Oehrlein, our department's plasma expert, replies: "That is correct - either the first ionization energy of the H2 molecule or of the H atom."
@materialsatumd oh yeah, and what in the world is Bobby (if i heard it right) doing inside the chamber without sleeves? I worked a little in a physics lab (condensed matter through laser super-cooling) and I found out that oil is the HARDEST thing to get out of a vacuum system. (I guess since you are opening and closing the system frequently and it's not an application that needs that low Torr it doesn't particularly matter. I just cringed the first time I saw =] )
@boilingbubbles We forwarded your question to Bobby (who is now an alumnus) and he replied: "For our experimental research reactors, we make [a lot of] effort to minimize contamination from the outside. We wear gloves and make sure our skin does not make contact with the inside of the chambers. Of course in actual semiconductor fabs, wafers are almost never handled by human hands. Wafers are loaded into plasma etch chambers by robotic arms from load locks that are under vacuum."
@pivotsreborn Professor Gottlieb Oehrlein, our department's plasma expert, replies: "Since the plasma consists of charged particles, the answer is yes. Depending on magnetic field strength, either only electrons (low field strength), or both electrons and ions, will respond."
@sockschappercat well, if talking about halo, really, all plasma weapons should have infinite ammo, as plasma is made of gasses. i could tell you a way how energy sword could work but that would trail off subject:)
Great video, I learned quite a bit from it. Although I don't think it'll be in my exam!
One thing I don't understand is how a plasma TV works. Surely if it needs gas to create plasma, then the TVs will run out? Or have I completely mis-understood plasma? :\
Professor Gottlieb Oehrlein, our department's plasma expert, replies: "You are correct in that gas is required to produce the plasma. However, the gas is not consumed in the process of creating light, and therefore a plasma TV will not run out of gas. There are a number of sites that explain some of the details of plasma TV. A good summary is presented at [the org web site plasmatvscience]." (Sorry, we can't post a link in comments.)
@Wibble199 to mis understand plasma is just what this world wants! as showed, different gasses make different colours, so basically getting the 3 primary colours(red, green and blue) mixing them together, making it the same as an ordinary TV:)
Heated gas? What about the electricity needed? Isn't plasma in space electrified gas?

2.)solid
3.)liquid
4.)gas
5.)plasma
so plasma is the fifth state not the fourth

Professor Gottlieb Oehrlein replies: Blue light has a wavelength near 480 nm, which means that in a plasma gases that predominantly emit at that wavelength--such as the argon (Ar) used in the video--will appear bluish. However, the color of the emission is not just a property of the gas, but also depends on the electrical characteristics of the plasma.

is plasma a gas or a liquid? i know it's its own state, but. im just curious.
shocklification 1 year ago
@shocklification It's its own state, but you could say it is closer to being a gas than it is to a liquid.
Hellsslave666 1 year ago
@shocklification
Technically a gas but it doesn't behave like either a gas or a liquid, all the molecules are rushing around each other mush faster than a normal gas, the inability to anthropomorphise it with any current state leads it to it's own classification.

wow thank you for explaning plasma i tryed watching another videos but lacked the atension or knowlege to under stand it the way you put may it much more simple to under stand

Very useful, helped me understand plasma (to a mild degree). Thanks for this video. I'm surprised at how common plasma has become. When was plasma first discovered, and is it naturally occuring?
stephenB125 1 year ago
@stephenB125 Thanks for your patience while we were closed for winter break. Sir William Crookes was one of the earliest (not necessarily the 1st but arguably the best known) people to describe and work with plasma in the mid-19th century, but the first person to use the term "plasma" was Irving Langmuir in the early 20th century. Yes, plasma is naturally occurring. Lightning, the Northern and Southern Lights, and stars are examples.

@materialsatumd wouldnt northern lights be some what cold making it super cooled plasma?
smengel3 11 months ago
@smengel3 Professor Oehrlein replies: "The reason that Northern Lights are near the polar regions of the Earth is not because of the low temperature there, but because of the Earth's magnetic field. The latter traps charged particles, which collide with gas atoms and cause the emission."

A Plasma weapon would be extreemly powerful, it would punch a hole through anything.
NANOFORGE 1 year ago
@NANOFORGE depending on the temperature, maybe yes if hot enough. but generally, plasma weapons in games are highly unrealistic. they are... games.
hardstyle905 1 year ago
@hardstyle905 I'm talking about a realistic plasma weapon. Yeah plasma weapons in games are unrealistic, the ones from Halo are patheticly weak when in reality they would blow a hole the size of a fist in it's target and cause it to combust, but that depends on the temperature and the amount of wattage it used.

How would one create a vacuum with a gas in it?
Maybe I'm just dumb, but isn't the definition of a vacuum an airless space? So how can you get the air out without the gas to be tested?
Yokailo 1 year ago
@Yokailo The plasma processing team's equipment includes sealed chambers from which regular air is removed using a pump, creating the vacuum. Then, the chamber is refilled to a desired pressure with gas from a cylinder. Thanks for your interest in our video!

why cant we use plasma for weapons
underdogg98 1 year ago
@underdogg98
because the same reason why gas isn't used a projectile weapon
you have to think of plasma as a element in its gas form with alot of energy in it.
using it as say a bullet would not be practical as it would expand and lose most of its energy soon after its release.

@Mrloco0117 plasma can be generated infinite times, and the colour of plasma can generate colour, meaning you have a life long source of TV!!

so wait, would the energy required to turn H into plasma just be its first ionization energy? [given it was, of course, in the gaseous state]
boilingbubbles 1 year ago
@boilingbubbles Professor Gottlieb Oehrlein, our department's plasma expert, replies: "That is correct - either the first ionization energy of the H2 molecule or of the H atom."

@materialsatumd oh yeah, and what in the world is Bobby (if i heard it right) doing inside the chamber without sleeves? I worked a little in a physics lab (condensed matter through laser super-cooling) and I found out that oil is the HARDEST thing to get out of a vacuum system. (I guess since you are opening and closing the system frequently and it's not an application that needs that low Torr it doesn't particularly matter. I just cringed the first time I saw =] )
boilingbubbles 1 year ago
@boilingbubbles We forwarded your question to Bobby (who is now an alumnus) and he replied: "For our experimental research reactors, we make [a lot of] effort to minimize contamination from the outside. We wear gloves and make sure our skin does not make contact with the inside of the chambers. Of course in actual semiconductor fabs, wafers are almost never handled by human hands. Wafers are loaded into plasma etch chambers by robotic arms from load locks that are under vacuum."

@pivotsreborn Professor Gottlieb Oehrlein, our department's plasma expert, replies: "Since the plasma consists of charged particles, the answer is yes. Depending on magnetic field strength, either only electrons (low field strength), or both electrons and ions, will respond."

@sockschappercat well, if talking about halo, really, all plasma weapons should have infinite ammo, as plasma is made of gasses. i could tell you a way how energy sword could work but that would trail off subject:)

Great video, I learned quite a bit from it. Although I don't think it'll be in my exam!
One thing I don't understand is how a plasma TV works. Surely if it needs gas to create plasma, then the TVs will run out? Or have I completely mis-understood plasma? :\
Wibble199 1 year ago
Professor Gottlieb Oehrlein, our department's plasma expert, replies: "You are correct in that gas is required to produce the plasma. However, the gas is not consumed in the process of creating light, and therefore a plasma TV will not run out of gas. There are a number of sites that explain some of the details of plasma TV. A good summary is presented at [the org web site plasmatvscience]." (Sorry, we can't post a link in comments.)

@materialsatumd gas is everywhere, and as long as we are breathing there is still some gas, even if it all turns into carbon:(
lukekellycopy 1 year ago
@Wibble199 to mis understand plasma is just what this world wants! as showed, different gasses make different colours, so basically getting the 3 primary colours(red, green and blue) mixing them together, making it the same as an ordinary TV:)
