Chapter 36 Section 36

The alarm on the child's cell phone rang.Gongping looked at the time and pressed the alarm to stop.It was exactly half past six.Looking at the open workbook, Kyohei sighed.I basically didn't move the Chinese exercises, I just did a few questions to read kana and write Chinese characters.Although Tang Chuan tutored him to do some arithmetic exercises, he still had to figure out his own way for the Chinese homework.After finally convincing himself to start doing it, Kyohei couldn't concentrate no matter what.I couldn't do two questions, so I wanted to reach for the game console.He refrained from taking the game console, but this time he turned on the TV again.Coincidentally, animation was playing on TV.It's a movie I haven't seen before.Although it didn't feel very interesting, Gongping still watched to the end.Thirty minutes have passed just watching the animation.After watching it, Gongping obediently turned off the TV, but he was still not in the mood to do the questions.Honestly, he's been waiting for the moment the alarm goes off.

Gongping walked out of the room and came to the first floor.Before going to the banquet room, Gongping first took a look into the lobby, only to see Tangchuan Station in the lobby with folded arms, staring at the paintings on the wall.Hanging on the wall is the painting of the sea. "Doctor." Gongping called him, "Are you looking at that painting again?" "I was wondering, since when did this painting hang here?" "Well——" Gongping pondered for a moment, "It should have been hung there a long time ago. When I came here two years ago, the painting was already there."

"That's right." Tang Chuan smiled, raised his hand and looked at his watch, "Okay, let's go to dinner." In the banquet room, Cheng Shi is putting Tang Chuan's meals on the table.Dishes are still mostly fish and mussels. On the opposite side of Yu Chuan's meals, there are bowls and chopsticks used by Kyohei.Dinner at Kawahata's house tonight is hamburgers. "As usual, it looks and tastes pretty good." With that said, Tang Chuan sat down cross-legged. "Sorry. It's the same dishes all day long, with little variation." "No way. The fish in the past few days are different. This is a treasure trove of seafood."

"By the way." Gongping asked suddenly, "Chengshi, I have something to ask you. I went to the beach today and saw a very beautiful fish. It was very small and blue. I asked Uncle, Uncle Said it was to let me ask you, Chengshi." "A small, blue fish? About two centimeters long?" "That's right." Gongping nodded again and again, "It's as beautiful as a tropical fish." "That should be 'Kongque'." "Empty sparrow? Isn't it a fish?" Cheng Shi smiled slightly. "The accurate name should be 'Empty Damselfish'. That fish is very common here in Glasspool. For those who experience diving for the first time, the deepest impression is probably when they found the empty damselfish. The first time When I saw that fish, I also thought it was a moving gem."

"I was taken aback too. I was trying to catch it, but I didn't." "I'm sure you won't be able to catch it. But don't look at it looking pretty now, it will turn black in winter." "Is that so? But that's okay. Anyway, I won't go diving in winter." I'm gonna start now.After putting his hands together, Gongping picked up the knife and fork.The surface of the hamburger is grilled to the right degree, cut with a knife, and the oozing gravy and thick Spanish sauce are mixed together, steaming hot. "I think your dinner tastes pretty good too." Tang Chuan said.

"Then I'll cut a piece for you. But you have to use sashimi instead." "It doesn't feel too bad, I'll think about it. By the way—" Tang Chuan held his chopsticks in his hand, "I have a question to ask you." After speaking, Tang Chuan glanced at Cheng Shi. "What's the matter?" Cheng Shi straightened his back. "Who painted the painting hanging in the lobby?" Cheng Shi's chest rose and fell slightly.Gongping felt that she seemed to take a deep breath. She shook her head: "I don't know. What's wrong?"

"It's nothing, I'm just curious. Last time I talked about this with Gongping, I asked him where the sea was painted. At least, you can't see such a sea near here." Chengshi brushed the hair sticking to the ear to the back of the ear, and tilted his head. "I don't know. That picture hung in the hotel a long time ago. I never paid much attention to it, though." "A long time ago? You mean, before your family moved here, the painting hung there?" "Yes. I heard from my dad that the painting was given to my grandfather by someone else, and my grandfather hung it there afterwards. So, my dad probably didn't know much about it."

Chengshi picked up the ignition stick on the tray, and was about to put one end of the ignition stick under the stove on the table in front of Yu Chuan. "No need, I'll make some myself." Tang Chuan said, "Just put the ignition stick there." With a puzzled expression on his face, Chengshi answered "Yes" and put the ignition stick back on the tray.Afterwards, she said "please take it slowly" and stood up to leave. "The sea in that painting—" As he spoke, Tang Chuan looked at her back, "It was seen from the hills of East Glass. I just went to confirm it."

Cheng Shi stopped.Not only her legs, but her whole body stopped in an instant.Cheng Shi turned his head slowly.Her movements were as stiff as a rusty robot. "Huh?" Cheng Shi's voice sounded weak.There was an unnatural smile on her face. "East Glass? Is that so?" "You really don't know?" Tang Chuan asked. "I haven't even thought about it." "Even if you really haven't thought about it, you just need to look at it to see where the sea is, right? Aren't you more familiar with the sea in Glasspool than anyone else? You even built a personal website. "

"I rarely go to East Glass." "Is that so? Isn't it written on your blog that the sea overlooking Bolipo from Dongli is the most beautiful?" There was a fierce light in the corner of Chengshi's eyes, and her voice began to become sharp: "I never wrote that kind of thing." Tang Chuan smiled wryly, "You don't need to be angry, do you?" "I am not angry……" "If you didn't write it, then I probably misunderstood it. It seems that I'd better apologize to you." "No, it's not necessary. Do you have anything else to do?"

"No, not anymore." Tang Chuan poured beer into the glass. Excuse me.Cheng Shi turned and walked out of the room.Her back looks a little listless. "Is what you said just now true?" Kyohei asked Yu Chuan, "Doctor, have you found the sea in that painting?" Ok.Yu Chuan replied casually, and poured soy sauce into the small dish.Afterwards, he picks up a small dollop of wasabi with the tip of his chopsticks and stirs it into the soy sauce.Even these movements of his feel like a scientific person. "I even ran over to have a look. It seems that you seem to care about this?" "The word 'care' means 'curiosity is stimulated'. Ignoring curiosity is the greatest sin. The greatest energy for a person's growth is curiosity." Gongping nodded.But he kept thinking in his heart why Tang Chuan always spoke in this tone. Yukawa reached for the ignition stick on the tray.Press the switch, and with a click, a flame burst out from the end of the ignition stick.Kyohei also has something like this at home.It was bought by their family for barbecue.But in fact, I only used it to cook a barbecue at home.Gongping's parents are very busy on weekdays, and hardly have time to go out for barbecue. Yu Chuan ignited the mass of solid fuel under the small stove on the table with a lighting stick. "Do you know what this container is made of that is now roasting on the fire?" On top of the small stove on the table was a white container.However, it looks different from ordinary containers.Gongping stared at the container carefully and said, "It seems to be made of paper." "Yes, it's made of paper. So, this container is called 'Paper Pot'. Don't you think it's weird? Since it's made of paper, why won't it be lit?" "Probably something has been done." After hearing Kyohei's words, Yu Chuan tore off a small corner from one end of the paper pot with his fingers, held it with chopsticks, and moved the ignition stick in his left hand to it.Although the paper didn't burn immediately, it gradually turned into black ashes.Seeing that the tips of the chopsticks were about to be burned, Tang Chuan stopped. "If it is ordinary paper, it will burn immediately. Yes, this paper has undergone some fire-resistant treatment, but it is not completely incombustible. It cannot be explained clearly based on what you just said of." Kyohei put down the knife and fork in his hand, and crawled to Yukawa's side. "Then why didn't it burn?" "Look inside the paper pot. Not only vegetables and fish, but also soup. The soup is actually water. What is the boiling point of water? You are already in the fifth grade, you should know this, right? " "Yes, one hundred. In the fourth grade, we even did experiments." "You filled the flask with water and measured the temperature while heating it?" "Yes. When the temperature is close to one hundred degrees, the water will start to bubble." "So, what happened to the thermometer after that? Did it keep going up?" Gongping shook his head and said, "I haven't been promoted at all." "Is it? Water turns into gas at 100 degrees. On the contrary, when water remains liquid, it will not exceed this temperature. In the same way, as long as there is still soup in the paper pot, it doesn't matter No matter how you heat it under it, it won’t burn. Because the ignition point of paper is about 300 degrees.” "So that's what happened." Gongping crossed his arms and stared at the flame of the small stove on the table. "Then, let's continue with the next experiment." Yu Chuan moved away the glass containing the beer, and picked up the paper round coaster underneath. "What happens if you put it on top of solid fuel?" Kyohei looked at the coaster, and then at Yukawa, and replied tremblingly, "It will burn".He always felt that Tang Chuan was setting himself up on purpose. "I guess so." Yu Chuan's answer surprised Gongping. "What. What kind of experiment are you doing?" "Take it easy. Well, what if the situation changed a little?" Yu Chuan picked up the teapot on the side and poured the water in it onto the coaster.The coasters immediately became soggy.The water in the teapot even wets the tatami, but the physicists ignore it completely. "What happens if you put it on solid fuel?" Gongping started to use his brain.It is estimated that the answer will not be too simple.Perhaps, what I said about the paper pot before is a reminder.He began to think over and over in his mind what Yu Chuan had said before. "I see." Gongping said, "It will still burn. It's just that it won't be ignited immediately." "why?" "Because the paper has been wet with water. It will not be ignited until it is completely dry. After it is dry, it will naturally burn." "Hmm." Tang Chuan said blankly, "Is this your final answer?" Gongping nodded and said, "Yes." "Okay." After speaking, Yu Chuan put the water-wet coaster on top of the solid fuel.The fuel comes in a canister, and with the coaster on, it feels like the canister has a lid on it. Gongping stared at the coaster for a while.Its center gradually turned black, and it felt as if flames would burst out from the blackened part at any moment.But after a while, the flames still didn't come out. Yukawa took off the coaster.The fire in the small tube has been extinguished.ah?Gongping couldn't help but exclaimed.He turned his head to look at Tang Chuan, as if he was asking "why". "The key to the problem is that the solid fuel is contained in a small tube. Whether solid fuel or paper, there must be oxygen when burning. However, if the small tube is sealed with a coaster, Oxygen has a hard time getting into the canister. However, if the coaster is not wet, the flame may burn through the coaster before it goes out and get oxygen again. Because the coaster is already wet , so as you say, it didn't burn right away. Also, damp paper is better than dry paper at trapping air." Yukawa ignited the solid fuel again with the ignition stick.After that, he put the wet coaster on the small tube, and immediately removed it.Just like that, the fire in the small tube was completely extinguished. "It feels like magic." Gongping said. "Has anyone taught you before that if the oil in the frying pan is burning, you should not rush to pour water on it? In this case, it is best to use a damp cloth to cover the frying pan , Let it cut off the oxygen. When an object burns, there must be oxygen. If there is no oxygen, the fire will go out. If there is not enough oxygen, there will be incomplete combustion.” "Incomplete combustion? Is that the phenomenon you mentioned during the day?" "Yes." Yukawa re-ignited the solid fuel, "Incomplete combustion will produce carbon monoxide gas." Kyohei recalled what Yukawa said when he was sitting in the van during the day.Why did Chongzhi have a stern face at that time?Not only Shigeharu, but even Setsuko had a gloomy expression. "What's the matter? Don't do it yet?" Tang Chuan asked, "If you don't eat the hamburger, it will be cold." "Yeah." Gongping crawled back to the original place.
