Chapter 578 Thermos Bottle
Looking at the heavily guarded gate of the Lord's Mansion, Wells, the former alchemist, lingered in the open space in front, so much so that the guards on guard cast a suspicious look at him.
Finally, he adjusted his clothes and walked towards the door with a serious expression.
Now Wells has dual identities as a professor of chemistry at Wyss College (a title invented by Lord Graeman) and the head of the chemistry laboratory (the other is Hoff, who is older than him). Man, also an alchemist from Jingyao), according to Earl Grayman's past performance, he is one of those "high-level talents" who are given special courtesy by the Earl, and he is usually respected. And Wells's character is also the type to say what he wants, and he has always been outspoken in front of the lord.
But this time, although he came with determination, he hesitated, hesitated, and even feared at the last moment.
Wells wanted to find out what Paul was talking about, which had something to do with the rebellion in Arda not long ago. Needless to say, this is a very sensitive matter. Although Paul Greenman usually laughs with everyone and makes harmless jokes with him, it will not matter. But after all, he is a lord and a ruler. When he is truly When it comes to the core thing of this type of person - power, it is likely to change to another face immediately, and that rebellion is aimed at taking away his power, and even his life.
Wells knew that his request might offend the lord.
Wells was happy that Paul could put down the rebellion, because he had never met a lord who was so supportive of alchemy or chemistry. When the rebels in Lake Town spread rumors that the lord had been killed , he was sad, on the one hand because of Paul who appreciated him, and on the other hand because he didn't know that the next lord would still be willing to pay for the chemical laboratory.
However, there are some things that must be done even if they offend the lord.
Wells handed his pass - a new measure after the rebellion - to the guard who came to inspect, and entered the castle gate after a body search.
...
“Ah, my dear Wells, you came at just the right time.”
When Wells pushed the door in, a familiar voice sounded. It's from Paul.
Weasel did not meet Paul in the lord's office, but was led to the lord's workshop, or laboratory. This did not surprise Wells. Everyone knew that Count Paul Grayman was an inventor. In addition to performing his daily work as a lord, he often tinkered with strange things in his so-called workshop. When someone came to visit at this time, Paul would call them into the workshop to show off his new invention.
And Wesl was not surprised to see another person in the workshop - Guy Burns, the supervisor of the machinery factory. He was a frequent visitor to the workshop. The lord often mixed with him to discuss machinery-related matters. problem.
Speaking of this person, Wells' mentality is a bit complicated. On the one hand, they are both leaders in their respective fields and admire each other. On the other hand, the machinery factory and the chemical laboratory are both big money hogs and fierce fund-raisers. competitor.
After saluting Paul, Wells and Burns greeted each other.
"Lord Grayman, I am here this time..." Wells wanted to express his request anxiously.
"Oh, please listen to me first...or, watch me do it first." Paul interrupted him, with a look of excitement on his face at this time.
Looking at the table in front of Lord Wells, there is a large glass bottle placed on it. Different from ordinary glass bottles, the bottle body seems to be made of two layers of glass.
Wells: "This is...?"
Paul: "Hoo hoo, this is my newly designed thermos kettle."
Wells: "Thermos kettle?" "Yes. "It's a thermos." Paul explained to him: "You see, after several years of hard work, the New Life Movement we launched has popularized the new way of drinking water in major towns - drinking boiled water, but not everyone Families have sufficient funds to buy fuel during non-winter periods, so we have set up facilities in major towns. You can buy boiled water for drinking by paying a few copper coins, but it is a pity that the boiled water will get cold very quickly, and currently The traditional insulation technology - wrapping cotton or fur on the container has very limited effect. Therefore, I designed a new insulation technology, which is this thermos pot. ”
Paul pointed to the double-walled glass bottle.
Wells stared at it for a while and asked in confusion: "What is the reason for making the bottle like this? What mechanism can it keep warm?"
"We know from daily life experience that [heat] It can be transferred. You see, when you are close to the flame, you will feel the heat. Furthermore, when you bring ice water and a cup of boiling water together for a while, the ice water will become warmer, while the boiling water will not be so hot. This What does it mean? I speculate that the so-called [heat] is like water, water flows from high places to low places, and [heat] is transferred from high temperature places to low temperature places - of course, without other intervention. "
Paul did not elaborate too much on "no other intervention" and continued: "So, the [heat] in boiling water... Let's put it another way - heat - where is it transferred? "< br>
Wells: "On a vessel holding boiling water?"
"Oh! That's inevitable." Paul said, "But eventually the vessel cooled down, so the heat didn't Didn’t end up staying there.”
Wells looked at Burns, who just looked at him with a smile.
Wells thought about it again, "Air? Because the space near the boiling water becomes hot."
"Haha! It's exactly what I thought!" Paul shouted happily, " Yes, air. The air near the boiling water receives heat and continues to transfer it to the cooler air further away. Eventually, the water and the air near it become cooler, and everything is so logical."
"So, I think, if there is no medium near the boiling water - that is, any object on which heat can be transferred, including air, then the boiling water will not become cooler?"
"So..." Wells looked at the strange water bottle, which was made of two layers of glass. There was a small hole in the outer glass, but this small hole led to the mezzanine space between the two layers of glass. He somewhat understood the meaning. What is the main thing to do?
"Yes, I'm going to evacuate the air between the two layers of glass and create a... create a vacuum barrier."
Wells: "Vacuum?"
Paul clicked Nodding: "A space where there is no air and nothing, uh... at least there is nothing that we can see and perceive now."
When the lord was explaining some things Wells was used to always adding some confusing supplementary information.
“Without the transfer medium, the heat will stay on the water in the bottle and the inner glass wall - this is what I deduced. Of course, there is still a little medium, after all, we cannot let these two The layers of glass are not in contact with each other at all, but I guess it is just like a thick pipe flows quickly and a thin pipe flows slowly. As long as there is less medium, the heat will dissipate slowly and the cold will slow down. So..."
Paul pointed to another object on the workbench, a piece of machinery Wells had never seen before.
"I commissioned Guy to make a device - an air pump, or you can also call it - a vacuum pump."
Guy Burns stood proudly on the side Breasts rose.
