Steel, Guns and the Industrial Party Across the World Chapter 574

Looking at the heavily guarded gate of the lord's mansion, the former alchemist Wells lingered in the open space in front of him, so that the guards on guard cast suspicious glances at him.

In the end, he straightened his clothes and walked towards the door with a dignified expression.

Wells is now the professor of chemistry at Wyss College (a title invented by Lord Graeman) and the head of the chemistry laboratory (the other is Hoffman, who is older than him, who is also from Jingyao) The alchemist), according to Earl Graham's performance in the past, he belongs to the kind of "high-level talent" who is given special courtesy by the earl, and he is respected on weekdays. And Wells' character is also the type of saying what to say, and he has always been outspoken in front of the lord.

But this time, although he came with determination, he hesitated at the last moment, hesitated, and even got scared.

Wells is looking for what Paul said, which is related to the rebellion in Arda not long ago. Needless to say, this is a very sensitive matter. Although Paul Greiman laughs and laughs with everyone on weekdays, it's okay to play a harmless joke with him, but he is a lord and a ruler after all. When it comes to the core thing of this kind of person - power, it is likely to change to another face immediately, and the rebellion was aimed at taking away his power, and even his life.

Wells knew that his request might offend the lord.

Wells was happy that Paul was able to settle 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 was killed, he was sad. On the one hand, it is to appreciate his Paul, and on the other hand, he does not know that the next lord is still reluctant to pay for the chemical laboratory.

However, there are some things that must be done even if the lord is offended.

Wells handed his pass-a new measure after the rebellion-to the guards who came forward to inspect, and entered the castle gate after a body search.

"Ah, my dear Wells, you have come just in time."

When Wells pushed the door and entered, a familiar voice sounded, it was from Paul.

Wiesel did not meet Paul in the lord's office, but was led to the lord's workshop, or laboratory. This didn't surprise Wells. Everyone knew that Earl Paul Greiman 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 people into the workshop to show off his new invention.

And Wiesel was not surprised to see another person in the workshop—Guy Burns, the supervisor of the machinery factory, a frequent visitor in this workshop, and the lord often mingled with him to discuss machinery-related issues.

Speaking of this person, Wells has a complicated mentality. On the one hand, both of them are leaders in their respective fields, and they admire each other. competitor.

Wells and Burns greeted each other after saluting Paul.

"Master Graham, I'm here this time..." Wells anxiously wanted to express his request.

"Oh, please listen to me first...or let 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 was a large glass bottle on it. Unlike ordinary glass bottles, the body of the bottle seemed to be made of two layers of glass.

Wells: "Is this...?"

Paul: "Hey, this is my newly designed thermos."

Wells: "The thermos?"

"Yes, the thermos." Paul explained to him: "You see, after several years of hard work, the New Life Movement we launched has popularized a new way of drinking water in major cities and towns—drinking boiled water, but not every day. Every family has sufficient funds to buy fuel during non-winter seasons, so we have installed them in all major towns, and you can buy boiled water for drinking by paying a few copper coins, but it is a pity that the boiled water will cool down quickly. The current insulation technology - wrapping cotton or fur on the container has very limited effect. So, I designed a new insulation technology, which is this thermos."

Paul pointed to the double-walled glass bottle.

Wells stared at it for a while, then asked suspiciously: "What is the reason why the bottle is made like this, and what mechanism can keep it warm?"

"We know from our daily life experience that [heat] can be transmitted. You see, when you are close to a flame, you will feel heat. Further, when you take a step of ice water and a cup of boiling water next to each other for a while, the ice water It will become warmer, but the boiling water will not be so hot. What does this mean? I speculate that the so-called "heat" is like water, water flows from a high place to a low place, and "heat" is transferred from a high temperature place to a low temperature place —without other intervention, of course."

Without elaborating too much on "no other intervention," Paul continued, "So, where is the [heat] in the boiling water... Let's put it another way—the heat—to where?"

Wells: "On a vessel in boiling water?"

"Oh! That's for sure," Paul said, "but eventually the vessel cools too, so the heat doesn't end up there."

Wells looked to Burns, who just looked at him with a smile.

Wells thought about it again, "Air? Because the space near the boiling water gets hotter."

"Haha! It's the same as I thought!" Paul exclaimed happily, "Yes, air. The air near the boiling water receives heat and then continues to pass to the air with a lower temperature farther away, and finally the water and the air near it It's getting colder, and everything is so logical."

"So, I thought, if there is no medium near the boiling water—that is, everything that heat can attach to and transfer, including air, will the boiling water not be cold?"

"So..." Wells looked at the strange water bottle, which is made of two layers of glass, and there is a small hole in the outer glass, but this small hole leads to the interlayer space of the two layers of glass~www.mtlnovel.com ~He kind of understands what the lord wants to do.

"Yes, I'm going to evacuate the air between the two panes of glass and make a... make a vacuum compartment."

Wells: "Vacuum?"

Paul nodded: "There is no air, no space, er... at least nothing that we can see and perceive now."

The lord always added some confusing supplementary explanations when explaining some things, and Wells was used to it.

"Without a transfer medium, the heat stays in the water in the bottle and the inner glass wall—that's what I deduced. Of course, there is still a little medium, after all, we can't keep the two layers of glass from touching each other at all, But I guess it's like thick pipes flow fast, thin pipes flow slowly, as long as there is less medium, the heat will be lost slowly, and the meeting will cool slowly. So..."

Paul pointed to another object on the workbench, a mechanism Wells had never seen before.

"I commissioned Gai Yin to manufacture a device—an air extractor, or you can call it—a vacuum pump."

Guyon Burns on the side proudly puffed out his chest.
