@darkpigion that's not what I meant. I know what sublimation is. I meant is there a process where it gots so cold that a gas goes straight to a solid?
@Ldsguy01 Its called Sublimation. If you look at the Iodine video (at least, i think its the iodine video) you can see a reaction that gets so hot that the solid iodine turns into iodine gas.
I HOPE the person holding the video cam , if there was a person, was wearing a face shield when the fire extinguisher was turned on... still I am getting the points of this video.
and.. the problem with CO2 dust here is that it condensates H2O from the air in to the ice, because it has about -100'C, hence.. you gonna have slightly wet place afterwords..;)
This is the way Nature removes CO2 form the air.. simple as it is. The funny thing is that people panicking ;) One volcanic eruption produces the amount of CO2 equaled to those that the human population produces for 50 years.
CO2 + H2O = H2CO3 this reaction can be carried on where the final product will be amongst other products.. a salt ;) NaCl.. table salt ;)
@Blackberrypipe LOL, that is typical denier nonsense! Humans currently emit about 35 billion tons (over 17,000 cubic KILOMETERS at about 2 kg/m3) of CO2 every year - just how would a volcano emit 50 times that in one eruption (actual volcanic CO2 is just 100 million tons a year, and most importantly, is balanced with CO2 sinks, or even outbalanced over the past few tens of millions of years). And no, natural processes to remove CO2 only work over long timescales.
@ms63129 I can agree with Blackberrypipe. Many scientific research indicate that the production of Co2 by humans is nothing compering to volcanic eruption. What about methane..? HUGE clouds of methane, SO2 are produced by every volcanic eruption..
Nature very easily remove all the staff in order to keep balance. Nothing on Earth is the same , in the other hand, everything is changing constantly and has got some pattern.
When someone says: 'climate is changing' I have a great lough;)
@MLKingXII "Scientific research"??? Really? From whom? And I mean actual scientific research; Google "USGS CO2" and click the USGS volcano/climate link (they show 260 million tons as the highest estimate for volcanic CO2); even Pinatubo produced only 50 MT of CO2, about half a days worth of human emissions. Also, SO2 causes cooling, not warming.
@MLKingXII Interesting and good cause for thought comment here;... in reference to methane >>> I have read there seems to be a tremendous amount of methane in the Gulf of Mexcio possibly due the Deepwater Horizion oil spill. Hmm I wonder what effect that would cause and... I could be wrong about what I have read. What do You think ?
@nyx211 because the atmospheric pressure inside the balloon was much higher than outside of it; maybe as the balloon fell to the ground, the rubber didn't stand the impact and ruptured, so the quickly escaping air gives out an explosive sound.
anyone wanna try a science experiment(not really much science actually) get one of those extinguishers and put a half inch pipe in the nozzle(i cut a part first for easier fitting). then use duct tape. and marbles coated with a layer of cellophane tape. and reload down the "barrel". it shoots far. and if hits walls the marbles crack. dont shoot anybody though, iguess it could break bones and will put urself in trouble, and ruin relationships, and get grounded
@xarlz159 whats grade 9??? haha im not familiar with the system in america. sorry. and thinking more of it i guess its not so efficient. not easy to liquefy gas. and then at least a closed container will be needed. and yeah im just in my first year in college. must be because of the difference in syllabus. maybe in more developed countries the syllabus is faster....
Well, sapphire windows aren't absolutely critical. All you need is dry ice, a plastic pipette, and water. You crush the dry ice, put the shavings in the pipette, dunk the end into water and clamp the end tightly (using your hands). Eventually, you will get liquid CO2 and then a nice explosion.
also, sorry, would there be any chance that the "evaporating, melting?" dry ice would have any chemical reactions with the thermal material? would it give off any toxins? i've seen a sewn together mylar/fabric sheet i'm going to cut up and use. maybe ill punch one or two holes in the thermal fabric ..
i have a question.. if you had a block of dry ice, a decently insulated beverage cooler, and a piece of camping thermal material.. if you loosely wrapped the dry ice block in the thermal material and placed that inside the cooler then closed the lid.. granted you had a tiny hole drilled into the bottom of the cooler, granted the lid of the cooler wasn't locked shut for precaution, roughly how long would that drill hole slowly shoot out co2 gas?
Guys if we mix CO2 with for example Na. Do they react?, I don't think. CO2 is so unreactive, why? Na wants to give the 1 electron, but why they don't wanna take it? The hungry oxidating O, why doesn't take it?
@bprzybysz sorry now I can see, oxygen atoms are stealing electrons from metal atoms with some energy, I bet it will take less energy with Na atoms to steal Oxygen from CO2 :)
@bprzybysz CO2 is not a polar molecule. So the charge is evenly distributed, that's why it is unreactive. You see, water is a polar molecule as Oxygen has an extremely high electronegativity (it's attraction of electrons) and creates a very slightly negative side, and the hydrogen is very slightly positive (we're talking very small, intermolecular size). Thus it is a great solvent as the slightly charged sides rip chemicals apart, such as NaCl, creating an ion of Na+ and Cl-. Hope this helped!
Wow very neat I have never seen liquid CO2. What would happen if you fired a short laser pulse set at a frequency that could break up the molecule? What form of carbon would be produced?
@salerio61 yeah, at first upon exiting their vessel, they are at room temperature. but you need to understand that CO2 should be gaseous at room temp and pressure. so its easy to deduce that they will absorb heat and turn into gas (which is quite a lot as latent heat of vaporisation is quite high). thats why when handling solid CO2, people use those gloves.
As a few people have commented, I should point out it is a coal station (Ratcliffe-on-Soar). Yes the cooling towers still produce steam... But other parts (in the shot) do produce CO2.
Not that it's vital, but I was aware of the issue and chose the shot accordingly.
Another piece of trivia for locals... though it is called Ratcliffe-on-Soar Power Station, it takes its water from the River Trent, not Soar!
@wassahilden and, for the ones who are worried about global warming, an interesting info: water vapour is a much stronger greenhouse gas than carbon dioxide :)
@steveUys carbon dioxide is definitely NOT a pollutant, and it is also essential for the chemistry of life. It might, however, because of its power of displacing oxygen in the environment, kill a person or an animal by asphyxia if it is suddenly released. In 1986 a lake in Cameroon called lake Nyos suddenly released a huge amount of carbon dioxide which was trapped in the bottom of the lake, displacing oxygen and killing 37 people of asphyxia.
co2 is so cool.. litteraly ;-P i have a friend who work in an icecream factory, so i`ve played a lot with dry ice (solid co2). at halloween parties or regular parties you can fill plastic cups with a bit of water, and ad small chuncks of dry ice to create a bit of fog ;-) and if you fill water and dry ice into plastic soda bottles, you`ll create a small bomb.. just remember to keep your distance from it when it blows up ;-)
Heehaahaa!! I used to do the same when I worked fast food/convenience store. Every time we got Ice cream delivery + a non hectic day + boss was away we played around with the dry ice.
I still remember the horrid creaking noise it made in the stainless steel tub when we was stuffin it with dry ice.
The mist flowed over so nice!
And every observant customer used to ask whether something was on fire in the back rooms when they saw the "smoke" roll out!!
Love this. I don't even know which part to comment on, but I thought it was particularly interesting to learn some about how CO2 is used and produced industrially.

I just love you guys and think what you do with these videos is fantastic. I sometimes think popularizing science and/or educating the masses does as much for science as actual research. Thank you for your videos!
@bereal666 Co2 isn't dangerous to the climate. With out it all life would cease to exist. All plant life depends on Co2 for photosynthesis. The byproduct is O2, which animal life breathes. Its a circle. Saying that Co2 is dangerous is also kin to saying that H20 is dangerous.
But H2O IS dangerous! Thousands of people drown in it every year, and mass condensation of water vapour causes tropical storms, resulting in even more damage! Not only that, but water vapour is also a potent greenhouse gas. So if anything, H2O is far more dangerous to both human life and the environment than CO2 could ever be.
It makes the environment thrive. Availability of water seems to be the only restriction to life.
The albedo effect of the water vapour clouds also cancels out a lot of solar radiation. Without it we could be even more screwed than we are now- climatewise.
It can be lethal to humans, yes, but it's also necessary to survive. in the end any molecule can kill. You just have to have (ingest/breath) enough of it.
We would also die in an atmosphere or ocean of CO2.
What poses the danger is not that there is CO2 in the atmosphere. The danger is posed by the rapidly changing amount of CO2. Life on earth has evolved for the past few million years with levels of CO2 that have never been higher than 300 ppm.
We humans are conducting a runaway experiment by releasing CO2 that has been sequestered for millions of years and by destroying the natural CO2 sinks.
Minor nitpick: CO2 works as a fire extinguisher because it *displaces oxygen* in the fire chemical reaction, also: as it comes out cold it helps lowering the temperature of the burning material.
I remember the first experiment i did with CO2, i was about 7 i think... My older cousin had got hold of some solid CO2 (dry ice) from an icecream cart, and we put about 20-25g (around 20 pieces of about 1 gram) each in a 0,5L cola bottle with about 0,2L warm water, sealed it, and threw it down a hill. When the bottle gave in to the pressure and ruptured it sounded like an explosion.
It's also fun to put in punch bowls at halloween :)
I am extremely thankful for videos like this , Education needs to hold your attention to truly be effective and Periodicvideos does just that. 5 stars :)
@ P00P0STEROUS Essentially they use water as rocket fuel, with a few other thing thrown in besides but the main constituent is an oxygen - hydrogen burning reaction which only releases H2O, good idea though
Nice vid... I was pleasantly surprised to see that this was a multi-part video. Too hard to fit it all into 7 minutes, eh?
Any plans on doing water soon? Biologist here, so keeping my eyes peeled for that one. That vid's gonna have to be at least three or four parts, though, hehe.
When he used the balloon to illustrate that CO2 is a gas, he should have noted how much heavier it is than an air-filled balloon. CO2 tends to collect near the ground and a balloon filled with it drops quicker.
Hmm... I could swear I read something about oxygen poisoning when breathing pure oxygen...
Seems this only occurs when under more than one atmosphere of pressure (as stated by Canonpixmalogitechko... what a name). It does have to due with only being oxygen.
It does not have anything to do with the breathing of pure oxygen. What causes oxygen to become poisonous [for adults] is when the partial pressure of oxygen approaches 2 atmospheres.
Breathing normal compressed air when diving will become poisonous if you dive deep enough....although you will experience nitrogen narcosis first.
The balloon looks like that model in A Clockwork Orange that Alex uses to kill the Cat Lady.

bereal666 2 years ago
@bereal666 Co2 isn't dangerous to the climate. With out it all life would cease to exist. All plant life depends on Co2 for photosynthesis. The byproduct is O2, which animal life breathes. Its a circle. Saying that Co2 is dangerous is also kin to saying that H20 is dangerous.

But H2O IS dangerous! Thousands of people drown in it every year, and mass condensation of water vapour causes tropical storms, resulting in even more damage! Not only that, but water vapour is also a potent greenhouse gas. So if anything, H2O is far more dangerous to both human life and the environment than CO2 could ever be.

More dangerous to the environment?
It makes the environment thrive. Availability of water seems to be the only restriction to life.
The albedo effect of the water vapour clouds also cancels out a lot of solar radiation. Without it we could be even more screwed than we are now- climatewise.
It can be lethal to humans, yes, but it's also necessary to survive. in the end any molecule can kill. You just have to have (ingest/breath) enough of it.
We would also die in an atmosphere or ocean of CO2.

Yep, that's was the point. It's both lethal to and necessary for life. We live on a thin margin, surrounded by oblivion!
saintaureus 2 years ago
Glad we agree.

@bereal666
What poses the danger is not that there is CO2 in the atmosphere. The danger is posed by the rapidly changing amount of CO2. Life on earth has evolved for the past few million years with levels of CO2 that have never been higher than 300 ppm.
We humans are conducting a runaway experiment by releasing CO2 that has been sequestered for millions of years and by destroying the natural CO2 sinks.
The impacts have only just begun.

Minor nitpick: CO2 works as a fire extinguisher because it *displaces oxygen* in the fire chemical reaction, also: as it comes out cold it helps lowering the temperature of the burning material.

I remember the first experiment i did with CO2, i was about 7 i think... My older cousin had got hold of some solid CO2 (dry ice) from an icecream cart, and we put about 20-25g (around 20 pieces of about 1 gram) each in a 0,5L cola bottle with about 0,2L warm water, sealed it, and threw it down a hill. When the bottle gave in to the pressure and ruptured it sounded like an explosion.
It's also fun to put in punch bowls at halloween :)

I'm waiting for CO2 to somehow become rocket fuel. I'm just not sure about that middle step.
P00P0STER0US 2 years ago
@ P00P0STEROUS Essentially they use water as rocket fuel, with a few other thing thrown in besides but the main constituent is an oxygen - hydrogen burning reaction which only releases H2O, good idea though

My notion of burning CO2 was a bit like the middle step in the Underpants Gnomes business model. 1: Collect underpants 2: ??? 3: Profit!
But hey, the future may reveal something amazing that will provide a use for CO2.

Nice vid... I was pleasantly surprised to see that this was a multi-part video. Too hard to fit it all into 7 minutes, eh?
Any plans on doing water soon? Biologist here, so keeping my eyes peeled for that one. That vid's gonna have to be at least three or four parts, though, hehe.

when he says it has 2 bonds, how do we know that
lejink 2 years ago
O2 has two bonds, illustrated by the water molecule, 2 H's plus an O.
C has 4 bonds, as illistrated by CH4, methane gas.
kshackleton 2 years ago
When he used the balloon to illustrate that CO2 is a gas, he should have noted how much heavier it is than an air-filled balloon. CO2 tends to collect near the ground and a balloon filled with it drops quicker.

inhaling CO2 is fatal, but what it you drank it?

inhaling only one type of gas is fatal...
Kargoneth 2 years ago
@Kargoneth
nonsense, inhaling only oxygen is not fatal.
kshackleton 2 years ago
It is if you inhale it under pressure (about 30 kPa). Divers sometimes kill themselves if they get the gas mix wrong.
Canonpixmalogitechko 2 years ago
Yes, I was aware of that. However, that has nothing to do with it being one type of gas....as was claimed.

Hmm... I could swear I read something about oxygen poisoning when breathing pure oxygen...
Seems this only occurs when under more than one atmosphere of pressure (as stated by Canonpixmalogitechko... what a name). It does have to due with only being oxygen.
Kargoneth 2 years ago
It does not have anything to do with the breathing of pure oxygen. What causes oxygen to become poisonous [for adults] is when the partial pressure of oxygen approaches 2 atmospheres.
Breathing normal compressed air when diving will become poisonous if you dive deep enough....although you will experience nitrogen narcosis first.
The breathing of a single gas is irrelevant.
