And if the ozone isotope produced by pollution at ground level is the same kind in the upper atmosphere, why don't we work harder to release, or pump, it up to higher altitudes?
I always assumed that ozone was a ring shaped molecule like benzene. But it turns out it's a linear molecule as per the professor's model. Probably why it's so unstable...
I wonder if it's possible for an O³ allotrope to exist in a ring under the right conditions?
@L00NGB00W Ozone cannot form a ring. It's a rookie mistake on exams in the first year of college. Ozone is a resonance structure from O = O - O to O - O = O. The central atom is sp² hybridized. The angle in this molecule is about 117° . The Lewis structure could suggest a ring is possible, but don't be fooled by it. If you somehow manage to squeeze ozone in the right angle, a ringlike structure would be unlikely or dissappear almost instantly.
I thought the crystals that caused ozone depletion in the upper atmosphere were actually CO2 crystals, but the prof seems to know what he's talking about.
People say that you must have a well ventilated printing room, because the printing lasers ionise the air and create O3. So... Why not just set up solar powered printing lasers at the south pole, and repair the ozone hole? *shrugs* Seems simple to me.
When the chlorine atom loses the oxygen atom and goes out for more, what happens to the newly freed oxygen atom? Wouldn't it simply re-form with other oxygen to make O2 or O3?
@TheReaverOfDarkness I was thinking the same thing, it's still an oxygen atom, isn't it? o.O Maybe it could be that, since Cl is constantly binding oxygen atoms, when it binds oxygens, that's simply one less oxygen absorbing UV, thus more UV reaching ground?
@tjd07x That doesn't seem to make sense, as the free oxygen would be so temporary. Perhaps the Chlorine breaks Ozone far faster than it re-forms, leaving many free Oxygen atoms that are unable to re-bond fast enough to prevent the ozone layer from weakening. And then perhaps a lot of the free Oxygen atoms pair with other free Oxygen atoms, preventing them from forming Ozone entirely, until they get struck by a UV photon.
All speculation on my part. I wish periodicvideos would come explain it!!
@TheReaverOfDarkness If I recall this correctly (it's been a while since I learned this in school) the problem was this: O² + O -> O³ and O³ + UV -> O² + O is what happens normaly. Now here comes our bad element X: X + O³ -> XO + O² and XO + O -> X + O². So essentially what now happens is this: O² + O -> O³ and O³ + O -> O² + O². First of all the Ozon is of no use if it doesn't use the harmful UV and second you take all the O and create O² from it but you need O to form O³.
@TheReaverOfDarkness eventually, yes... this is why the holes eventually (after a very long time) repair themselves... but bear in mind the ozone layer is fairly substantial and took a long time to form, you can see how a sudden loss of O3 causes a hole.
The chemistry that destroys ozone requires maintenance of the polar stratospheric clouds into springtime. The temperatures required are those below about 195 K at which nitric acid trihydrate crystals are thermodynamically stable.(part 2 of 2)
The argument as to why the hole is more pronounced over the Antarctic rather than the Arctic is due largely because the temperatures over the Arctic in the lower stratosphere are higher. This is because the upper atmospheric circulation is faster in the northern winter/spring. This is because the northern topography generates more gravity waves than the southern counterpart. The polar vortex is also more stable in the south. Together this means the temperatures are lower. (part 1 of 2)
So after all, anything we do on this planet technologically, means that we're polluting the planet. So my idea of replacing jet engines on planes, with ion thrusters, fails from the start, as ion thrusters or any other electrical type thruster, produce massive amounts of ozone. So that's not good at all. We solve a problem, only to create another... Shit!
@cheerdiver Ozone dissolved in water has far fewer health consequences than chlorine. The reason it isn't used as widely, at least in the English speaking world, is because it degrades to O2 very quickly so it needs to be produced on site.
@TunioMir No, the sky is blue because air molecules scatter blue light well but not red light. The ozone layer is extremely thin, the air around us is thousands of times thicker than ozone.
Up until now I was on the fence (yet leaning at least) about the anthropogenic nature of global warming but this puts all that nonsense to bed for me. Thank you Prof for another simple explanation of a complex problem.

it looks like someone s trying to expose that land...
i have some questions though: why are there more molecules there? what makes them gather? ;what happens to the o2 after the cl takes an o? ;and can there be o7 out there? or even o20?
also, as i get it, if it s o2, or o4,o6,o8?, it s actually not bad for you; but good.
Would it be possible for periodicvideos to SHOW us liquid ozone. I mean, I know it's explosive on being allowed to boil an all, but it's just something I've always wanted to actually SEE. There doesn't seem to be any existing video, or any good images of it in existence of it anywhere, and it would provide fantastic demonstration of the quantum mechanical three body problem that gives rise to the color of liquid oxygen and ozone.
Great video,especially because it's filmed outdoors.Like a lecture in ancient Greece. :)
You should really consider making a clip about the actual ozone as there are very few people in the world who had seen it..
Additionally, you could toss a critique or two about the ozone quackery that's going on lately. In case you didn't know, there are charlatans letting people breathe ozonized air and injecting it into their blood vessels, or ozonating their blood and returning it back to the bloodstream.
@Ricalloo Many sources produce O3 and one of them is high voltages creating coronas and sparks. Most photocopiers have "corona wires" that apply a charge to the paper so the ink will cling to it and this is what make ozone in your xerox machine.
I was watching this in the peroidicvideos channel and then I saw those chicks totally throw the prof. off and I knew the top comments would be about it.... annnd I was right :-)
Ohhhh, the resonant bond three body absorption, those sexy clip on shades, that tetrahedral bond demonstrator, that sultry come hither pose in the hot Australian sand!! It's all too much professor! I'm only human, you beguiling vixen of valence electrons, you!!!
Why is it that CFCs, which is a heavy compound, can make their way to the upper atmosphere and ozone at ground level doesn't. What mechanism in nature selectively pushes heavy compounds upwards and keeps lighter compounds at ground level? Shouldn't all gases be in some sort of current which circulates them? Shouldn't CFCs at ground level attack the ground level ozone and disassociate it just as it does in the upper atmosphere?
I've wondered this for years and never heard an explanation.
Yep, the cfc's were in spray cans, air conditioning gas and refrigerator gas. Most of them have been banned now but there are still a lot of old cars and air conditioners around with the old gas.
@demios99 The depletion of the ozone layer has NOTHING WHATSOEVER TO DO WITH "GLOBAL WARMING".
Nichts. Nada. Zilch. Zero.
If you watch the video again - and, this time, pay attention to the real and actual facts - then you'll see that ozone is O3 (three oxygens), which is not CO2 so there is no "CO2 taxes" at all, and the actual point here is that ozone high in the atmosphere helps absorb UV radiation from the Sun.
Which is about preventing skin cancers and other detrimental health effects.
@KlaxonCow It actually does - O3 absorbs cca 99% of UV light emitted by the Sun, thus preventing excess warming of the planet's surface. Ozone holes, allow for larger exposed surfaces of the Earth to be directly irradiated by the Sun, increasing overall levels of energy inside the ozone layer. Simultaneous release of the co2, methane and other green house gasses prevents thermal energy from leaving the planet, essentially keeping the energy stored inside the Earth's ozone layer.
@KlaxonCow If you read my response to you, you'll see what I said! My ironic comment about taxes and g.w. was related to the dogma politicians serve us every day on the news - ozone depletion=global warming, which of course is not directly related, as I explained in the said reply. The goal of my comment was to mock politicians and their paradigms and not claim that CO2 causes O3 depletion!
@passwordresetisbroke Your ignorance is what kills you. If you realse oxygen in the atmosphere (Where would you get it, if not from the air) it would make the atmosphere more oxygen rich (percentage of oxygen in the atmosphere is 30%). But, oxygen does not have anything to do with carbon dioxdie they do not react and it would just wate money and making more CO2 trying to get the O2 up in the atmosphere.
@99Chemicals It's rather that your ignorance kills you. We have solar energy in excess, so we don't need to emit any CO2. And O2 can be found in water and released through electrolysis! Excess H2 and CO2 would be used to create complex hydrocarbons and O2 would, again be released in the atmosphere. Link - oceanethanol com /CO2/Technology html
@passwordresetisbroke The sheer volume you'd need to pull of a plan like that, makes this highly impractical. Getting oxygen is also a problem. Can't take it from the air, so it would have to come from water. This releases a lot of Hydrogen, which you can't really store so it would also go up in the air, adding to the greenhouse effect. Add to that all the carbon dioxide made to split the water and you'll have a second Venus before you seal the hole in the ozone layer.
@passwordresetisbroke That's the most absurd thing I've ever heard. Did you even look at the pictures showing the giant o-zone gap? It's likely the size of the united states. And you wanto take aircraft that are... In comparison to the planet, tiny, tiny, tiny, tiny. And you wanto release oxygen from them. What?!?
Maybe think about what you're saying before you say it next time.
What particularily is impossibly impractical about flying aircraft and releasing gasses/substances, more difficult programs have been accomplished (ie the Panama canal). What I mentioned would in practice be no different than cloud seeding (look it up) an activity which is somewhat commonplace.
Regardless, it was idle banter, was wondering if enough 02 would correct the problem or create more. Wasnt interested in practicality.

Shouldn't CFCs at ground level attack the ground level ozone and disassociate it just as it does in the upper atmosphere?
I've wondered this for years and never heard an explanation.

Yep, the cfc's were in spray cans, air conditioning gas and refrigerator gas. Most of them have been banned now but there are still a lot of old cars and air conditioners around with the old gas.

Could anyone tell me why they dont just release huge amounts of oxygen out of high altitude aircraft to try to combat this effect?

@passwordresetisbroke Because then they can't sell you the whole "global warming" story or force you to pay CO2 taxes

@demios99 The depletion of the ozone layer has NOTHING WHATSOEVER TO DO WITH "GLOBAL WARMING".
Nichts. Nada. Zilch. Zero.
If you watch the video again - and, this time, pay attention to the real and actual facts - then you'll see that ozone is O3 (three oxygens), which is not CO2 so there is no "CO2 taxes" at all, and the actual point here is that ozone high in the atmosphere helps absorb UV radiation from the Sun.
Which is about preventing skin cancers and other detrimental health effects.

@KlaxonCow It actually does - O3 absorbs cca 99% of UV light emitted by the Sun, thus preventing excess warming of the planet's surface. Ozone holes, allow for larger exposed surfaces of the Earth to be directly irradiated by the Sun, increasing overall levels of energy inside the ozone layer. Simultaneous release of the co2, methane and other green house gasses prevents thermal energy from leaving the planet, essentially keeping the energy stored inside the Earth's ozone layer.

@KlaxonCow If you read my response to you, you'll see what I said! My ironic comment about taxes and g.w. was related to the dogma politicians serve us every day on the news - ozone depletion=global warming, which of course is not directly related, as I explained in the said reply. The goal of my comment was to mock politicians and their paradigms and not claim that CO2 causes O3 depletion!

@passwordresetisbroke Your ignorance is what kills you. If you realse oxygen in the atmosphere (Where would you get it, if not from the air) it would make the atmosphere more oxygen rich (percentage of oxygen in the atmosphere is 30%). But, oxygen does not have anything to do with carbon dioxdie they do not react and it would just wate money and making more CO2 trying to get the O2 up in the atmosphere.

@99Chemicals It's rather that your ignorance kills you. We have solar energy in excess, so we don't need to emit any CO2. And O2 can be found in water and released through electrolysis! Excess H2 and CO2 would be used to create complex hydrocarbons and O2 would, again be released in the atmosphere. Link - oceanethanol com /CO2/Technology html

@99Chemicals Or you could simply plant a lot of trees and solve the problem :)
demios99 5 months ago
@passwordresetisbroke The sheer volume you'd need to pull of a plan like that, makes this highly impractical. Getting oxygen is also a problem. Can't take it from the air, so it would have to come from water. This releases a lot of Hydrogen, which you can't really store so it would also go up in the air, adding to the greenhouse effect. Add to that all the carbon dioxide made to split the water and you'll have a second Venus before you seal the hole in the ozone layer.

@Alphasys Thanks fella, I literally know nothing of the subject and wanted to know why :D.

@passwordresetisbroke That's the most absurd thing I've ever heard. Did you even look at the pictures showing the giant o-zone gap? It's likely the size of the united states. And you wanto take aircraft that are... In comparison to the planet, tiny, tiny, tiny, tiny. And you wanto release oxygen from them. What?!?
Maybe think about what you're saying before you say it next time.

@MyNamesNotLuke And maybe you shouldnt be such a cunt, eh?
What particularily is impossibly impractical about flying aircraft and releasing gasses/substances, more difficult programs have been accomplished (ie the Panama canal). What I mentioned would in practice be no different than cloud seeding (look it up) an activity which is somewhat commonplace.
Regardless, it was idle banter, was wondering if enough 02 would correct the problem or create more. Wasnt interested in practicality.
