Vol 4 Chapter 193: Fire air

When most people were addicted to sports, and a very few people went to explore Siracoul, in a beautiful manor on the outskirts of Zhenzhi City.
Oli was wearing a moon-white robe, leaning against Arnold, and carefully opened a roll of parchment.
Arnold looked at her affectionately, closed his eyes, and quietly acted as a cushion.
"Weighing gas? Interesting experiment report."
Oli looked at the latest "Elements" journal with great interest. The author of this report was named Laval. He used coal, lead red and saltpeter, iron filings and dilute sulfuric acid, iron filings and dilute nitric acid to place objects. Heat on the barrel of the gun, and then collect the generated gas on the water surface to determine the total amount of "gas" extracted from various substances.
"This device for measuring the weight of gas is very interesting. It's just that weighing is too limited. "Animals, plants, and minerals are all rich in air." This conclusion is of course correct, but it is too simple and too vague."
Arnold opened his eyes, looked at Oli suspiciously, and closed his eyes again.
Ollie took a trip to Arnold’s arms, lifted the scroll above her head, and read softly:
Elasticity is not an inherently unchanging property of air particles. As we know, air particles are affected by the large amount of acid particles and sulfur in the air. The strong attraction of particles and salt particles makes it easy to change from an elastic state to a fixed state."
She leaned on Arnold’s brows and frowned:
Is this the recognition of atoms of all things? I also agree with atoms. The microscopic world may have indivisible particles, but air does not seem to be a kind of particle. Human breathing consumes some of the air. If the ingredients are consumed, the flame cannot burn under this kind of air.
Do you think it is, brother Anuo. "
Arnold nodded with a bewildered face, and hugged Oli vigorously, as if afraid that she would disappear.
Since the resuscitation, Oli’s strength has remained at the first level. She has never constructed her own basic spell model. Except for the magic model of Mingxing Pluto based on "Magic Mechanics", her soul secret space has been empty.
"Brother Arnold, I don't want to rely on the foundation of "Magic Mechanics" of Master Ace. Although "Magic Mechanics" is perfect, I yearn for the wind more."
Arnold listened to Ollie's murmur, and said softly: "I have a little understanding of the latest theory. It seems to be a phlogiston theory. Gas is the wind element of the past four elements. Why don't you build the foundation based on it?"
Ollie adjusted her posture in Arnold’s arms and said softly,
I think gas must be complicated. I don’t plan to construct a basic spell model until the basic composition of gas is determined, and although the phlogiston theory seems reasonable, The experiment also made sense, but there was no real confirmation!
I have always been skeptical of phlogiston theory. "
Arnold gently hugged Ollie, and said in a low voice: "I don't know much about magic research, but I know that if you doubt it, you can't practice it. Since you are skeptical of phlogiston theory, then It's better to experiment and see if you can overthrow it!"
Ollie's eyes lit up, and she kissed Arnold happily: "It makes sense, but you don't have to overthrow it. Either prove that there is phlogiston or prove that there is no. In short, experiments are needed to verify."
If you want to experiment, you need to collect the most cutting-edge research in this field.
Oli has been thinking about related papers in the dream world for several years, and she has accumulated enough theoretical knowledge.
A few days later, the latest issue of "Magic" was published, and Oli opened it for the first time, and happened to see an article "On Air and Fire" published by Betty.
"I believe that most elemental wizards have discovered that the volume of a defined volume of air will shrink after long-term contact with certain substances.
We use sulphur lime water solution, linseed oil, and water-moistened iron filings to place in the air. After a few days, about a quarter of the air is absorbed, and the remaining air can extinguish the small candles.
We can think that these substances are rich in phlogiston, or rich in combustible substances. The remaining gases are different from ordinary air in that they contain no combustible substances.
Because if this gas is a combination of air and phlogiston, and its volume is reduced, then it must be denser than ordinary air.
But filling this gas in an extremely thin flask and weighing it precisely, it was found that it not only couldn't balance with the air in the same volume, but was even lighter.
...
Therefore, air is composed of two fluids with different properties, one of which does not exhibit the property of attracting phlogiston at all, while the other fluid accounts for one-third or one-fourth of the total air mass.
I call the former dirty air, and the latter fire air. "
Oli looked at it as she thought about it. This division of fire air and turbid air is in line with Betty's phlogiston theory, and it also proves that gas is composed of at least two different types of air.
"However, gas is not necessarily two elements, it may be more."
Ollie spoke softly while continuing Betty's paper. Betty's greatest contribution to this research is to purify "fire air".
"Using the phosphorus combustion test, it can be determined that combustible substances are combined with fire air. Therefore, I believe that heat = fire air + phlogiston. Since heat = fire air + phlogiston, you only need to find a substance that is more attractive to phlogiston than fire air. It’s just as attractive."
Oli continued to think about what could purify the "fire air", Betty gave the answer.
In Betty’s previous experiment ~EbookFREE.me~, it has been found that nitric acid has an immediate effect on metals. The phlogiston collected by the metal is removed to produce red smoke (nitric acid + phlogiston). In order to subject the nitric acid to heat, let it be the same as potash. Combine it to fix it, put the saltpeter obtained in a retort and distill it at high temperature together with the alum oil to release nitric acid.
Tie the monster bladder filled with lime milk to the mouth of the retort and absorb the red smoke released. The bladder is filled with a colorless gas, and the small candle in the bladder is lit, which will emit a dazzling light.
Ollie immediately left "Gensokyo" and came to reality to repeat the experiment. Sure enough, she succeeded in producing a unique gas. This gas not only makes the flame burn more intensely, but also lasts longer. If inhaled into the lungs, it will There is a rare sense of ease.
"This kind of gas can not only make the flame burn, if it is pulled away, the remaining air will suffocate people or animals! It has great practical value and rescue value."
Ollie continued to read the "Magic" journal and found that this issue was actually an experiment related to fire and air.
In fact, the three founders of Betty, Bayern, and Logan have discussed and exchanged many times. Based on Betty's experiments, Bayern and Logan produced pure fire air by heating with mercury and heating with black manganese.
