Chief Scientist Carl Nelson demonstrates how to create liquid carbon dioxide from dry ice (solid carbon dioxide). 13abc anchor Tony Geftos is amazed by the transformation.
So, I'd just have to have a sufficiently strong pressure vessel to contain the gaseous CO2 in order to keep the rest liquid once the vessel returns to room temperature?
when co2 is at atmospheric pressure, it cannot maintain a liquid state, thats why it goes from a solid block to a gas immediately. when put in the pipette and sealed, it allows pressure to build inside the pipette, allowing for a liquid state to be achieved, however as the pressure builds inside the pipette, the plastic cannot maintain physical structure and bursts. when the pipette bursts, all the pressure that was inside is immediately reduced back to atmospheric pressure, which then immediately reverts the dry ice back to its solid form
Aliyah Watson you mean decrease the pressure right? Cuz temperature and pressure have a direct relationship and by decreasing pressure temperature drops and therefore it will get to a point in which carbon dioxide becomes liquid
@@Alisonn2 no, we have to increase the pressure to about 5.1 atm because at barometric pressure at sea level, co2 can only sublime. So, it is not only temperature that plays role in phase changes, pressure also plays a huge role. To understand this; you have to check what we call 2D phase diagrams; being Pressure vs Temperature the most popular.
I've never seen such a clear demonstration of the three states of carbon dioxide before! Neat! :)
1:51 it literally looks like cocaine 😂
Lol when he said inhale it
@@BW-xz6ol heh-heh wink wink ;)
“Will then… I want lots” 🤭🥴
I worked in Philippine Industrial Carbonics Inc. producer and distributor of liquid carbon dioxide here in phils

If you don't it becomes a bomb
You’re supposed to compress it into to a liquid while it’s a gas.
So, where’s the link to your scientific journal?
Even it is insulated from water its pressurized. Interesting..
Oxygen Not Included players:
so, pv = nrt ?
Why when it’s a liquid goes back to solid and not gas?
Probably because it's still very cold

@@adamdavis8655 :D
It was solid at normal pressure so when returned to normal pressure it also returs to solid form.
-109°F (He should have mentioned the units) (not C, not R, not K)
There’s a lot of experimental substances you can make. I thought about going back and making one.
Elon Musk just offered 100 million dollars to whoever comes up with the most efficient way of trapping CO2 from the Earth's atmosphere

😁👍
It’s be done. You can make hot ice. It’s all real.
3:59 why is going back to solid? the other guy is not interested on this important question.
who is here looking for ideas after Elon Mursk's 100M price?
You got me!
Just increase the pressure
yeeey right sis

Baby steps Bob! Baby steps!
Please How do take CO2 from gases emerging from combustion. E.g. wood burning?
Condense them into an oil.
Well, a lot of them started of cheap.?
Aye I love my city Toledo Ohio
Inhale it...
This was filmed on my 12th birthday
Just be careful. In LA ITS A FELON! Lol look it up.
so how do you make liquid carbon dioxide
Compressing it to 5.1 times atmospheric pressure
The scientist was incorrect about why it’s called dry ice… it’s middle school science…
