Pei Mengqing didn't expect that someone had already thought of her method and put it into practice. But thinking about the strange technology tree in this world, which even has vehicles, what else is there to be surprised about?
Soon, under the leadership of Qingyu, they rushed to the "Unified Research Center for Temperature Measurement" in the central area of Yanzhou University.
When the guard saw Qingyu, he asked a few questions and let Pei Mengqing and the others in.
After all, the Cat Clan is absolutely trustworthy, and no one will doubt that the Cat Clan is up to something evil.
However, the guard still informed the laboratory personnel of their arrival in advance.
After all, although the cat family is absolutely believable, sometimes they can't resist instinctively pushing some "spherical objects" and "pushing objects off the table", and they may also be attracted to some plants such as Polygonum spp. Take attention.
Maybe it will cause damage in the laboratory inadvertently...
Hearing that it was the cat clan coming, and there were three more of them, the laboratory immediately sent a steady experimenter to come and receive a few people.
Knowing that they wanted to see information related to thermometers, we immediately received them warmly.
Yanzhou University is not so optimistic about their research.
After all, there are only so many laboratories available and experimental funds are limited. Their messy experiments such as temperature uniformity are not so reliable at first glance.
What's more, it is indeed unreliable. It has been used for a year and a half and no useful results have been produced. Naturally, everyone is not very satisfied.
It must be said here that in this era, even institutions of higher learning do not understand that certain inventions and experiments require years or even decades of hard work before they can be rewarded.
At present, "science" has just started in this world, and it is still a short-term and quick-result scientific experiment and acquisition. Therefore, they failed to succeed in the short-term problem of temperature. It took an "unprecedented" year and a half to achieve success, and there was no success. Doubts are met with skepticism and ridicule.
"We have achieved a considerable degree of success so far. From a broad and broad perspective, we believe that air is the substance that has the greatest impact on temperature. You know air, right?"
The experimenter explained while helping Pei Mengqing and the others put on protective gear.
"You know, the gas we breathe, wind, is moving air."
Pei Mengqing didn't say more, she didn't say anything about what percentage it was made of oxygen and what percentage it was nitrogen.
He didn't know what this group of people were studying now. If he talked too much, it would be bad to be regarded as a future star in the research world.
He has now switched from science to the camp of cultivating immortals.
Can science allow him to travel through time and be reborn? Can it travel through interstellar space? Can it be split open with a sword and stop the flow of sea water?
cannot.
But cultivating immortals is possible, but what cultivating immortals is about is unscientific.
Of course, if one day scientists in this world can rationally use magic and spiritual energy to integrate them into technology, it will be treated as if he never said these words.
The researcher looked at Pei Mengqing appreciatively, thinking that he was a talent, and became more enthusiastic.
"That's right, but we haven't completely succeeded yet. We have only succeeded in a certain aspect of stability, although there are also many strange phenomena that we still cannot fully understand."
"What do you mean?" Pei Mengqing didn't quite understand the other party's inhuman words.
Going around and around, no one knows what you are talking about. Those who don’t know think that the guy is a bureaucrat, not a researcher!
"Well, that is to say, we can only test the temperature above a certain value, and there will be changes under certain temperatures." The researcher said.
Pei Mengqing decided not to listen to this guy's nonsense.
Only after entering the laboratory did he know how these experimenters studied temperature...
What they call a temperature instrument is a sealed, huge jar.
The jar contains a clear, colorless and odorless liquid.
"What's in here?"
Pei Mengqing decided to ask, lest she wrongly accuse them.
"We generally call it the source of life, one of the four great creations, and an important member of the five elements..." The researchers were still talking nonsense.
"You mean, there's water in it?" Pei Mengqing interrupted directly.
Experimenter: "There is such a name."
Pei Mengqing clenched her fist and almost punched him.
Just say it's water inside and that's it. It's so miraculous that people who don't know it think it's some extremely precious and rare material.
"So, you're saying you can't measure the temperature when the water freezes, right?"
The experimenter gave a thumbs up, indicating that Pei Mengqing was really knowledgeable.
The huge closed jar is densely marked with different scales, and each scale says something like "5 Zhurong" or "10 Zhurong".
It's just that the order of some numbers is reversed.
Now Pei Mengqing completely understood. After all, he had also studied junior high school physics and junior high school chemistry.
The density of water is maximum when it reaches 4 degrees Celsius above zero, and then decreases all the way, so that 1 degree Celsius and 7 degrees Celsius will be very close.
The reason why the experimenters made such a big jar is because if there is a lot of water, when the density changes, the overall volume change and water level height change will be more obvious, making it easier for them to label...
That is to say, they distinguish the temperature by the volume and water level height of the same amount of water at different temperatures...
In the short term, without taking into account the natural evaporation of water hanging on the top of the jar, or the air density and pressure of the closed jar, we can indeed barely get some temperature data that is not too outrageous...
It’s just that this is of no use!
It is better to take a sip of water at natural temperature. It is estimated that the temperature is safer than this complicated and huge garbage device!
Pei Mengqing sighed, covered her forehead, and decided to help:
"Water doesn't work, water is special, and water will freeze below zero, so it can no longer be measured accurately. Degree, you know? Just use this unit, don't worry about melting. Water can just freeze, which is zero. Use this as Standard, you can try to find other materials, liquids, for example... forget it, just say it.
"Mercury, use this one. This one is more sensitive to temperature changes and will not freeze when the temperature is very low. Only a small device can be used to create precise, reliable and portable tools that will not be affected by too many external influences. "
Mercury has a greater coefficient of thermal expansion and is far easier to use than water.
If we don't just say no, if we continue at this pace, these people may have to replace a lot of useless materials, and maybe even oil will be used.
Fortunately, mercury still existed in ancient times, and was nicknamed "mercury", "original water", and "liuzhu".
