This sounds like semantics, not science. I mean semantics is a science but "you know what i mean".
It's more than semantics because it fundamentally changes our thinking about what's happening at the microscopic level. And that changes the way we link other phenomena together and that changes our creativity about what other possibilities are out there.
@@ThreeTwentysix i was being facetious. In science it's never just about semantics because definitions are important. So the real question would be:
What is the scientific definition of boiling? How this definition is useful or what does it says about the underlying reality of what is happening?
Is there a long form video?
@@ThreeTwentysixI think it ultimately boils down to if it's a vapor, it boils. If it is a gas, it isn't essentially boiling.
There are no citations to this paper since 2001. What Does that mean? Is no one taking this as a serious science subject? I think its interesting because its a simple question easy to imagine but might be hard to answer.
Thank you Goodwin for the wonderful research and thank you Mr. Robertson for bringing forth such excitin and comprehensive educational content. Pepsi or Coca cola?
Thanks. My favourite is a Japanese cola called Mets, though I don't see it around much these days.
of course bubbling is almost equivalent to boiling. although the bp of CO2/H2O and bp of pure H2O are relatively far apart..
it's still about definitions of concepts..
once i drinked 90ish percent alcool it evaporated in my throat and i couldn't breath cool experience
I did that back in the day too ... That was not a pleasant experience at all 😅
Well the bubles of varbonatet(carbonatet this is the only redid)water does lower the temp of the liquid soo yea it kinda is boiling, it also leaves the state of being liquid when it fizzes, you could also do the same with alchohol and another liquid at another pressure and temp😅...
I never had the feeling I understand fizzy drinks!😢
I don't know for sure but I'm skeptical because as I understand the CO2 exists as -COOH then is chemically converted to CO2... soooo maybe not? But my gut says it's boiling so that's my final answer.
the only reason this wouldnt perfectly be correct is because youre not messing with the thermal energy since boiling is often seen as adding thermal energy to vaporize a liquid BUT due to the lack of pressure 3->1 (the pressure in a sealed carbonated drink i about 3 atmospheres) the pressure decreases and since the temp and the volume do not change it “boils” to accommodate the lack of pressure. NOW to prove if its boiling or not you would simply need to see how the thermal energy reacts since water is non compressible the thermal energy is the only variable and it should go down if it truly is boooooiiiiillllinnnnggggg as it would absorb energy to make the state change and if you want to understand what im saying ask 326 to explain this on a pv diagram cus thats the best way👍👍
You’re like an evil villain, except you’re not trying to take over the world. You’re trying to make chemistry intuitive and interesting. Mua ha ha ha ha!!
It’s falling out of solution, the CO2 was always a gas though. It was never liquid when it was in the beverage
You are extremely underrated! Keep it up and I’m sure you’ll make it.
That's what I keep telling people! 😄
You helped me so much in chemistry@@ThreeTwentysix
Liquids do NOT have to be pure to boil. The azetrope is evidence of this, and column distillation is probably an even better example.
As for CO2...I think it depends on your definition. If BP is the temperature (and pressure) at which the internal and the external pressures exerted on the liquid are equal, then the CO2 is boiling due to the reduced atmospheric pressure outside of the packaged vessel.
would you say a solid precipitating out of a solution is freezing?
You are NOT going to like Goodwin's second paper. I'm planning a couple of videos on Goodwin's conjectures.
The prof is right. It's about nucleation.
It’s wonderful, that lack of distinction. Is this helpful for material sciences then? Phase transitions and what not?
It's helpful for being able to apply what we know about more conventional mixtures to extreme cases.
Most thought provocative chemistry content on UA-cam. Seen several videos. Instant favourite channel. Keep it up.
So from my understanding pressure has as much to do with the state of matter as does heat. If there is types of ice that exist in extreme temperatures because they are also under extreme pressure, then a highly pressurized fluid/gas mix having the pressure relieved would cause the mix to boil at a low temperature? The drink doesn't 'fizz' until you open it, right? *Pfffwchhhh!
Open the lid and pressure drops in the mix container. Its not hot, but is boiling? I think that would be the thinking... im just a fan of documentaries, not an expert by any means. Probably an overzealous layperson at best.
Is the water boiling, or just evaporating into a tiny vacuole of effervescent carbon dioxide?
And do I sound like I swallowed a dictionary, or what? 😉
What I think is irrelevant as I’m uneducated in the matter. I’m gonna read that paper first and tell you what I think after.
Can't be bothered. Too much toil and trouble.
So when I make spaghetti and put salt in the pot I'm boiling salt‽
No that doesn't work for me.
The CO2 gas may be a saturated solution with water vapor but that doesn't mean the water is boiling, no , it's just evaporating.
I would say that the boiling point would be when the water vapor pressure is high enough that it exceeds 100%rh of the CO2 (or whatever) gas that envelops it displacing that gas as its now a gas. That is , to put it another way, if you lower the temperature 1° and the water wont condense, you are at least 1° above its boiling point. Just past where humidity stops having any meaning as water is the gas,
First video in a long time which made me actually think about undergrad coursework.
I think I buy this one. Excellent work, sir.
People rarely if at all say they have a pot on the stove bubbling🤣🤣🤣🤣👀😳 Now that I've said it, I'm gonna start using that phrase instead 🎯🤓
Boiling is when vapor pressure matches external pressure right? If fizzy drink is open to air and all of the liquid is not vaporizing to replace escaping gas then I guess it’s not boiling but wtf do I know 🤷
Well it is doing that slowly just as ice is becoming colder when you introduces salt to it, it does it the same reason it changes state from solid to liquid and because saltwater has a lower point of solidifying it is taking the heat out of the ice and reduces the temp all the way down to the melting point of saltwater ice. This has been used for many ywars when you wantet to make gelato icecream 😊 it is also why some places salt the roads and other places dont it all depends on the temps...
The process we use to cause carbonation is different to boiling. We dont increase the temerature of the substance to have it bouble when we carbonate something, that is boiling.
When we carbonate something we infuse a gas into a liquid and pressurize it in a container.
At least that is how i see it.
I dont know is the cemical process is similar/the same. But the practical process is completly different.
We like to categorize things differently based on: process, looks, taste and sometimes feelings.
But boiling isn't necessarily just rising the temperature. It can also be changing pressure while keeping temperature constant.
I would say it's more about the molecules going from one state to another. The CO2 bubbles escaping the dissolution aren't boiling cause they were never in liquid form to begin with, they were only dissolved into the water as gas. That's how I see it at least.
@@adriasalarich exactly
I thought boiling was when a liquid turns into a gas. Not a gas coming out of a different liquid, though that could be seen as a bit of a grey area.
The fact that the carbon gas is taking a bit of the carrier liquid doesn’t mean much, after all, if that was the measure, liquids evaporate anyway.
The flip side of this is that solutions can boil, and just because not all the components are boiling doesn't mean the solution isn't. We consider distillation to involve boiling, for example.
@@hairymcnipplesbut the thing is, are the carbon molecules even boiling? To my understanding no, since they weren't in liquid form before, they were just dissolved gas. I could totally be wrong though.
