My Identity As A Schoolmaster Has Been Exposed

Xu Cong looked at the suddenly quiet group, and immediately sent another message over: "Go on! I won't disturb you."

The host was also dumbfounded in front of the phone at this time, so he had to bite the bullet and sent a message: "Ahem! Xu Cong, would you like to express your opinion? Of course, what we will discuss next is in a vacuum!"

"You also know very well that when discussing any physical issue, preconditions are very important!"

Xu Cong understood his intentions at once, and typed out another message: "Group owner, you don't need to explain, I promise not to leave the group, you continue, really, don't worry about me."

Group leader: "[Face expression]"

Although Xu Cong promised to the group owner that he would not leave the group, it does not mean that he would not block and no longer care about these people.

Xu Cong immediately blocked the group, and said silently: "It's really boring, this group of people, with this time, it's better to watch the drama and play the game."

When Yang Kaixuan finished washing and came back, he joined the discussion in the group. At the same time, he asked Xu Cong: "Xu Cong! What do you think of this question?"

"Have you seen everything in the group?"

"Most people insist that in a vacuum, raindrops will evaporate during the fall and will not fall to the ground."

Xu Cong was beating the king, doing two things with one mind, and replied: "This is only half right. The external pressure gun does have a huge impact on the state of the water."

Yang Kaixuan: "???"

Damn it!

Xu Cong's opening is so professional!

He immediately shared Xu Cong's words in the group, must share it in the group, and show them to those who are still arguing with blushing faces.

Yang Kaixuan directly relayed it to the group, and when these words were posted, many people in the group really stopped arguing.

To give face and respect is one aspect. Among them, more are, want to see the true strength of Xu Cong.

Seeing is better than hearing!

Yang Kaixuan continued to ask Xu Cong: "Xu Cong, what do you say?"

Xu Cong continued to say to him: "I remember that there is a water phase diagram on the Internet. You can look for it. From the water phase diagram, you can see that pressure affects the freezing point of water."

"The solid, liquid, and gaseous phases of water are three phases. The phase diagram is to distinguish the solid, liquid, and gaseous regions in a coordinate system."

"The horizontal axis of the coordinate system represents temperature, and the vertical axis represents pressure. Whether water is solid, liquid or gaseous at different temperatures and pressures can be directly obtained in the phase diagram."

After listening to Yang Kaixuan for a while, he realized that he couldn't remember, so he directly clicked on the voice call.

At this time, on Xu Cong’s side, the style of painting changed suddenly, and he shouted: "Why! Why did you suddenly become a group? Don’t! Hey!

Suddenly, everyone was stunned.

"What does the last sentence mean?"

"???"

Yang Kaixuan immediately explained to them: "Xu Cong is playing games, playing games..."

Everyone heard the explanation from war correspondent Yang Kaixuan, and all were petrified on the spot.

"Playing games? I f*ck! Is this one mind and two purposes?"

Puff!!!

After Xu Cong finished this wave, he continued to say to Yang Kaixuan: "In the picture, the khaki area represents the solid state, the green area represents the liquid state, and the blue area represents the gas state."

While talking, he digressed again!

"It's a group! It's a group!"

"You Nizi, keep up, don't fall behind."

Xu Cong was playing black with Lin Mengjiao. In order to let Lin Mengjiao not be too nervous about studying, he had to learn to relax. He played games with her and used the team voice.

When Yang Kaixuan heard his words, he could naturally guess that he was playing a gangster game with his sister. He was speechless on the spot and subdued this god.

Everyone in the group saw that he had digressed again, and they were very helpless, and they wanted to scold his mother.

After Xu Cong finished this wave of team battles, he thought for a moment about where he said just now, and then continued: "When the temperature is lower than a certain value, which is 251.165K, no matter what the external pressure is, the water will not flow. Exist in liquid form."

"When the pressure is lower than 611.73 Pa, no matter what the temperature is, water will not exist in liquid form."

"At lower pressures and lower temperatures, water can only exist in a solid form."

I will talk about this for a while, then switch to the game with Lin Mengjiao. Xu Cong is really busy.

"Go bring the line, don't help me all the time! Yes! Then, go and open up your vision."

When Yang Kaixuan saw him like this, he tried not to record Xu Cong's voice about the game, but Xu Cong switched freely and did not give Yang Kaixuan a chance to react.

All kinds of alien texts suddenly appeared in the crowd: "%￥##￥"

Xu Cong: "That is to say, when the external pressure is small enough to approach zero; the external temperature is low enough to approach zero."

"This drop of water will suddenly enter a state where gas, liquid, and solid coexist. In layman's terms, the water will freeze while boiling."

After Yang Kaixuan posted this, he read the news in the group. Many people had the same question as him: "Will the water evaporate?"

Xu Cong smiled and continued: "No, it can only exist in the state of solid ice."

Yang Kaixuan frowned when he heard this answer, and asked incomprehensibly: "How to say?"

Xu Cong: "The evaporation or sublimation of water will take away heat, which will cause the remaining part of the ice or the temperature of the water to further decrease, thereby slowing down the rate of evaporation or sublimation."

"So the process of completely turning a small ice crystal into a gaseous state will be very long."

Yang Kaixuan was silent, and most of the people in the group fell into deep thought when Xu Cong said this.

But some people questioned, they also cited an example: "This is only theoretical! I can't think of such a specific situation in reality!"

Xu Cong's game was over, he looked at Yang Kaixuan with a blank face, smiled and asked, "Is it untrustworthy?"

Yang Kaixuan would naturally not behave like this, and said to him: "No, no, I'm just a little curious!"

Xu Cong chuckled, and then explained to him: "There are a lot of ice in the Kuiper Belt outside of Neptune in the solar system and the Oort Cloud further away."

"In addition, comets actually have an ice-like composition. They have shuttled in the universe for so many years, haven't they all evaporated?"

"If you calculate the speed of 900, it should be more than 400! Wait a minute, I will think about it!"

One second! Two seconds! Three seconds! Four seconds! Five seconds!

"About 447 meters per second, this speed should be the upper limit of the pistol ejection speed, but the water quality is too small, even if it can freeze into ice and hit a person, it is only a few joules."

Xu Cong's voice stopped abruptly, and Yang Kaixuan sent all of them to the group. Only then did Xu Cong notice that Yang Kaixuan was sending a message, and it was still a voice call.

Xu Cong immediately raised his head to look at him and asked, "What is this???"

Yang Kaixuan said directly to him: "Send your analysis and understanding to the group."

"If you don't play games now, there should be no game protection mode? There will be a message prompt, right?"

Xu Cong directly told him the truth without blushing and heartbeat: "No, I blocked the group."

Yang Kaixuan's eyes twitched after hearing this: "!!!"

Xu Cong, "Don't ask me! I'll go play a game again."

Without waiting for his consent, Xu Cong invited Lin Mengjiao, and Xu Cong was just about to start.

He received the private chat message that it was Xiaokang and directly asked Xu Cong: "Brother! Did you see the skin that I sent you?"

Xu Cong was puzzled, and he was suddenly confused: "???"

Soon, he remembered the incident, so he went to check it out, and it was true. Xu Cong replied, "Thank you."

After receiving the skin, Lin Mengjiao started the game with Lin Mengjiao, and directly put this Xiaokang aside.

Xiaokang was also very dumbfounded. Looking at the other party's prompt that he had started the game, he began to doubt life. He faced the live broadcast room and said with a sad expression: "Is it so realistic? I haven't had time to tell him, play a few games together! He started!"

Xiaokang decided to wait for Xu Cong.

He made a script some time ago, but the effect was not expected to be good, but there are still many people in the live broadcast room missing Xu Cong!

Because they firmly believed that Xu Cong was real at that time!

Recently, Xiaokang has done something fake. They yelled, hoping to call Xu Cong to continue the double row.

"As long as I can play a game with you, I will discuss it with you."

But Xu Cong didn't give him a chance at all. After winning this round with Lin Mengjiao, Xu Cong went down, so he was well off and waited for loneliness.

Just as Xu Cong put down his phone, Yang Kaixuan came over and said to him, "Xu Cong! Many people in the group are looking for you!"

"Ask, why add you as a friend, why don't you have a reaction?"

Xu Cong continued, "Didn't I block the group? Besides, am I not in the group? Why add me privately?"

Troublesome, Xu Cong still picked up the phone and checked the group news.

At the same time, I also took a look at this application friend interface: friend application: 40+!

There are more than 50 people in the group, and almost everyone wants to add Xu Cong as a friend.

In the group, even the group leader does not seem to be treated like this, Yang Kaixuan, that's an envy!

"You are too popular too!"

PS: I can't stand it anymore, I slept.

Beauty is important!

The little fairy wants to be beautiful!

Tomorrow will work harder to codewords!
