If you get this wrong, what happens to the dog? Tar is a mixture of many materials. If you didn't add anything to the stuff you distilled from wood then it's pure tar. How could you purify something that's pure to begin with?

If you can avoid the use of a solvent then you avoid teh problem of having to remove it, so warming the material up is good- if it works. If you add an alcohol it will probably act as an emulsifying agent which makes things harder. (The ammonium salts mat do this to some degree anyway.) What are you seeking to achieve?

It wouldn't. But if the tar is viscous then dilute acid will also fail to extract the amines from it. You dilute the tar, extract the amines and then remove the solvent.

How viscous is the tar? It might be easier if you dilute it with a solvent that you can remove later. Maybe cigarette lighter fuel.

Come to think of it... https://www.simplymedsonline.co.uk/cardiovascular/glyceryl-trinitrate-500mcg-tablets-gtn.html Other suppliers of volatile liquids in pill form are also available.

It's quite commonly what causes the problem in the first place. How do you put a fairly volatile liquid in a pill?

The ball is a capacitor- that's what it's for. And; fast as lightning, you worked out what the issue is.

What evidence do you have that the current is low? What would limit it?

As a rule those are not independent variables. Ohms law tells you how to calculate on from the other. Does anyone know why this myth persists? Why not? Twelve volts is twelve volts.

Eventually, you will end up with the big tank full of gas at the vapour pressure of the liquid in the small tank. So you can't transfer all of it, but you can get very close. On the other hand, getting very close would need you to use liquid nitrogen or something to cool the small tank. Not only is that uneconomical,but you risk embrittling the steel.

What's obvious is that only one of us is a chemist. But, back at the topic; iron rusts perfectly well in the dark, but not in the absence of oxygen. The ultimate reason why things degrade is entropy. https://en.wikipedia.org/wiki/Entropy

https://en.wikipedia.org/wiki/Daedalus Sunlight is pretty good at damaging organic materials, but doesn't usually harm metals (which reflect it- that helps) and inorganic materials.

Tobler formulated two laws, the second one (relevant to this topic) concerns geology and is sometimes referred to as "Tobler two" in the same way that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object such that f=ma . is sometimes referred to as "Newton two". You seem to be thinking about Tobler one. That's older than Tobler two, so it's not relevant to this thread. :-)

I know that. You know that. The next guy reading the thread may not know that. No You can essentially "distill" the CO2 into the smaller bottle if you cool it and/ or warm the big one. In principle you can shift almost all the CO2 that way.

Do not fill a gas cylinder with liquid. When it warms up, and the liquid expands, it will burst the tank (or the pressure relief if you are lucky). https://www.phmsa.dot.gov/sites/phmsa.dot.gov/files/docs/technical-resources/55771/calculation-and-verification-filling-ratios-liquified-gases.pdf

You seem to be conflating two different things; Turing's test and a Turing machine. As far as I know, no Turing machine would pass Turing's test.

You might argue that. But I don't think many would accept the validity of the argument.

Under the right conditions you can get CO to decompose into CO2 and C. https://en.wikipedia.org/wiki/Boudouard_reaction Re-electrolyse the CO2 and, eventually,you will convert it all to C and O2. The problem is (as ever) where to get the energy from.

Yes, really. We really are not speaking French. And, from WIKI, "It is based at the Pavillon de Breteuil in Saint-Cloud, France, a 4.35 ha (10.7-acre) site (originally 2.52 ha or 6.2 acres)[5] granted to the Bureau by the French Government in 1876. Since 1969 the site has been considered international territory" So it's really not in France diplomatically speaking, It is surrounded by France And "The Bureau International des Poids et Measures is not French, though its official language is?" is particularly ironic. England left the EU. The EU's principle official language is still English. It's a bit like Eurovision song contest winners; The UK loses, but English usually wins. The Catholic church is world-wide, but its official language is Latin.

I think we all agree on that. The authority isn't French, it's BIPM. The I stands for international. Diplomatically speaking, it's not even in France. Plus important encore, nous ne parlons pas français

Interestingly, Wiki doesn't follow that reliably. e.g This increases the density and temperature of the core until it reaches approximately 100 million kelvin, from https://en.wikipedia.org/wiki/Helium_flash Presumably because nobody would say it is 25 Celsiuses or 90 Fahrenheits outside

"100 million kelvins" is a very big room full of scientists. "100 million kelvin" is a temperature.

I disagree. The whole paper seems to be an interesting exercise in confirmation bias.

IQ is a measure of how well you do in IQ tests. It was originally designed to identify the children who were falling behind in school in order that they could be given better support. I'm sure we agree that's a worthy objective. Using it to compare people who are- by whatever criterion- average or above is, at best, misusing the tool. Getting into arguments about who has the bigger Dick, I mean the bigger IQ is unlikely to be productive.

You can't. The zinc will immediately start to dissolve.
