Rising: Ten Thousand Years Chapter 63: ：Literate the world

Low steam utilization. This is an extremely important question.

Ten thousand years ago, the steam engine was invented hundreds of years ago. This problem has also been studied by successive generations of scientists for hundreds of years, and they have been constantly improving and improving the utilization rate of steam.

This is a big problem. It's not just about saving raw materials. The steam utilization rate is low, the main problem is that the power is obviously weak. If the problem of power cannot be solved, the steam engine will never be popularized. Because its function will be tasteless...

Fang Hanxian raised his hand in embarrassment: "Mr. Li, can I ask a question?"

Li Zhen put the pen on his ear and said with a smile: "Han Xian, if you have any questions, just ask. Don't be cautious, everyone is crossing the river by feeling the stones, no one is higher or lower, just call my name."

Whenever there is a chance, Li Zhen will encourage Fang Hanxian who is very inferior. Let him become cheerful. He understood that Fang Hanxian had suffered more grievances than himself in the past ten years, and his inferiority complex was deeply rooted in his bones. Scientists can't feel inferior, knowledge is clearly armed to the teeth.

Fang Hanxian sneered, stood up and said, "Now... I don't have a clear concept to understand the problem and phenomenon of 'steam can be converted into power'. Can Mr. Li make a rough idea first, so that we can intuitively see the steam In fact, is it really a manifestation of power? Maybe you can intuitively see that steam has power, and the three of us can help you and think of some problems."

Li Zhen nodded and said, "Enze."

"Mr. Li is here."

"You bring a basin of water and a small wooden board."

"Yes, Master Li."

"Han Xian."

"In."

"You bring an alcohol lamp, and then a hose and a test tube."

"Yes."

“…”

Liu Jinghong asked: "What are you doing with these things?"

"Maybe you just see the teapot boiling water, and you don't have a very intuitive impression of steam power. After all, this is a new concept. I will do a small experiment to let you see its power."

"How?"

"You'll find out later."

After a while, the two took their things and ran back to the laboratory. When the two took things, they attracted the attention of other students. Everyone knew that Li Zhen led the team to study the steam engine project again, and they thought that there was progress, and they all ran over to watch the excitement.

After the two entered the room, other students also came, and the auditorium was completely surrounded.

"I heard it was researched?"

"So fast? Are you kidding me?"

"It's only been a few days, look, the sketch on the table is not finished yet."

"Then what is this for?"

"I heard that it is to let everyone see the principle and concept of the steam engine."

"What are you doing with a basin of water? What is the concept of this?"

“…”

However, Li Chen put the alcohol lamp on the wooden board, filled the test tube with water, covered the mouth of the test tube with a rubber tube, then wrapped the rubber tube around the test tube twice, and fixed the transparent head backwards. .

"Light it up."

The alcohol lamp was lit, and the flame immediately began to roast the test tube.

Li Chen put the burning wooden board in the water basin, but remained silent.

Everyone waited for a long time, but there was still no movement, they couldn't help staring: "What are you doing?"

"I thought I could move, but I can't."

"Can this show the principle of the steam engine?"

"I don't think it should be possible, but you see that there is no movement."

“…”

However, Liu Jinghong and the others suddenly understood that although the plank was quietly floating on the water, they had already seen the principle.

Fang Hanxian nodded and said, "Is it possible that when the water in the test tube boils, the board will generate power to run forward?"

Li Zhen said: "There is no need to wait until the water boils."

Suddenly, those students who came to see the excitement exclaimed: "It's moving!"

"It's really moving. I'm going, is it really moving?"

"Auto without wind?"

"Ah, yes, is this the principle of a steam engine? Steam can produce reverse thrust, so the boat moves."

"However, this thrust is a bit too small. This power is too weak. The legendary steam engine is simply a very powerful machine."

"But he proved the principle of steam, steam is really dynamic."

“…”

In the water basin, the boat floated by itself, and hit the edge of the basin after a while. But it is still moving forward, it misses, it is still moving forward, and then it changes direction and moves forward again. Here, the power of the boat itself can be clearly seen.

At this time, Li Zhen walked to the small blackboard and drew a container on the blackboard with chalk. Water was drawn with blue chalk in the container, and a few wisps of smoke were drawn with red red pen.

"Come here."

The three hurried to the blackboard. But the other students in the auditorium didn't leave, they all gathered around and looked at Li Zhen fixedly.

Li Zhen pointed to the container: "This container is filled with water, and the water is represented by blue. Now, there is a flame under this container to boil water. What will happen during the process of boiling water, Brother Jinghong? "

Liu Jinghong let out a snort: "During the process of boiling water... it happens, does it make the water boil?"

Li Zhen shook his head: "Han Xian?"

Fang Hanxian pondered for a while, pointed to the blue and said, "Did the water start to transform into another form during the process of boiling water? It turned into steam?"

Li Zhen shook his head: "It's close. Enze, tell me."

Qin Enze smiled bitterly: "I understand what it means. But I don't know why, I can't explain it clearly."

At this moment, a female student who was watching suddenly shouted: "Li Zhen, is it during the heating process. The water has become an invisible energy again? It has been transformed into another energy form?"

Li Zhenyi clapped his hands: "That's right. This is the principle of the steam engine, a very simple principle, but it is difficult for anyone to discover such a phenomenon without explaining it clearly. First of all, we need to know the three forms of water; Water, steam, and ice. There are two forms of water in the steam engine, the original water, and the steam that appeared later.”

"When the water in this container is not heated, it is water. After being heated..."

Li Zhen pointed to the blue line: "What comes out of the bottle mouth or the vent is the steam pressure. And the steam has thrust."

"When the water in this container is heated, the air inside the container will expand rapidly under the influence of heat energy. If we block the mouth of this container and continue to heat it, the air inside will expand as it continues to heat. Constantly expanding, at a certain critical point, the entire container will explode. A force emerges from the inside, which is the internal energy of the air. It will explode and expand, so it has the energy to push."

"And when we add a vent to this container ~IndoMTL.com~ there will be a place for the heat energy to pour out, and all the heat energy will erupt along the pour port. The force of this eruption is the power of the steam. Power. It is also an energy conversion process: from the chemical energy of water to the internal energy of air.”

After Li Zhen finished speaking, the audience was silent, and everyone was quiet.

Looking up, all the students took out their notebooks and hurriedly recorded these things in the notebooks.

Liu Jinghong wrote down every word Li Zhen said, and couldn't help but marvel: "Who would have thought that in the process of boiling water, there will be so many phenomena and so many incredible processes. I really understand the principle of this steam."

"Looking at the kettle before, I knew in my heart that the water would boil and there would be steam. But I don't know why there is steam. This is the reason."

“…”

Li Zhen smiled wryly, is this the sorrow of Kyushu?

Focus on results. rather than basic academics.

The faults of ancient products are not terrible. What is frightening is the gap in ancient science. The faults in the ancient sciences are not terrible, what is frightening is that the thinking of Kyushu people also has faults.

No one pays attention to academics anymore. No one pays attention to the research of basic theory anymore. Because studying theoretical academics will not make you famous, it takes time to verify.

However, an ancient product has been restored, even if you don't know the principle, it will immediately make you famous all over the world. This is the death of Kyushu.

The development of science, since I don’t know how many years ago, the world has entered a wrong path...

Li Zhen watched everyone staring at the simple steam principle in shock, and suddenly felt an invisible pressure in his heart. It seems that the world needs to be literate...
