Chapter 425: Chen Pingan

Lang Lang's voice sounded in the classroom.

"Establishment of chemical equilibrium: Under certain conditions, the state when the positive and negative reaction rates of reversible chemical reactions are equal."

"Chemical equilibrium has three characteristics. The first characteristic is that it is a dynamic process; then the second characteristic is that in an equilibrium state, △rG=0; the last characteristic is that the composition of chemical equilibrium and the process of reaching equilibrium The path doesn't matter."

"However, chemical balance also needs attention. Chemical balance is relative, conditional, and temporary dynamic balance... Next, do students know what is chemical equilibrium constant?"

Professor Zhai Yang does not need to project PPT in his lectures, and the formal expression mainly relies on the blackboard. For subjects such as mathematics, chemistry, and physics, the blackboard is yyds!

Formulas and calculations are soulless if they are not expressed on the blackboard!
I don't know why, but Professor Zhai Yang feels that teaching at Guanghua is more energetic than at Lu University.

After Yang Yang finished the class, she looked down at her watch and it was still 10 minutes before get out of class ended.

"Students, since there is still some time, let's review the content of the previous class."

Di Yang looked around at the crowd and asked with a smile: "Use everyone's favorite way of asking questions, then I'll call the roll."

There is no need for a roster, because there are only 24 students in the entire class.

Guanghua College adopts the system of general education. There are 87 students in the experimental class. The course selection is generally free, but there are some restrictions. For example, it is stipulated that there are two sections of physics, two sections of mathematics, one section of biology and one section of chemistry .

This chemistry is the course "University Chemistry" set up by him, which mainly talks about the principles and foundations of the four major chemistry, namely inorganic chemistry, organic chemistry, physical chemistry, and analytical chemistry.

The main purpose of general education is to strengthen students' quality education and inspire innovative thinking, and through various interdisciplinary content, find a major that interests you and suits your own development for intensive learning.

Otherwise, if you are admitted as a major in computer science, but actually the major in physics is what really suits you, what should you do?
Many people will say that they should change majors!
However, do you want to change majors if you want to?
Different schools have different requirements, the better the school, the harder it is to change majors!

For example, it is difficult to change majors at Peking University, but it is even more difficult to change majors that are popular.The first is to have a high final exam score, which ranks in the top 10% of professional scores in BJ University, which is full of strong people.

Only the top 10% of Peking University's professional grades can change majors...

Think about who can be admitted to Peking University, not to mention the popular majors such as finance, management, and computer, which require professional exams...so let's give up this idea.

Professor Zhai Yang very much agrees and appreciates the implementation of this characteristic system by Guanghua University.

A total of 24 people have chosen his course this semester, and they have memorized everyone's names after taking the class twice.

Di Yang glanced from left to right, most of the students held their heads high, and a few students shrank their necks for fear of being called.

"Song Hao."

After finishing the words, a boy in a black T-shirt sitting in the third row near the window froze, then stood up with a constipated face, scratched his head, and looked a little at a loss.

Di Yang raised his eyelids slightly and asked, "What is the essence of the first law of thermodynamics?"

"The essence of the first law of thermodynamics is..."

Song Hao's dandruff was about to come out, but he was really not interested in chemistry, but the school required him to take a chemistry course. He didn't plan to enroll in the first semester of his freshman year, but who asked his friends to pull him in.

Di Yang just looked at Song Hao with a smile on his face, without saying anything.

"Ha... so what is the essence..."

Song Hao's voice became lower and lower, and he looked at the person beside him, but the other person shrugged helplessly.

No way, the teaching building of Guanghua College is uniquely designed. In order to facilitate teaching, the classrooms are fan-shaped, which is much more convenient in teaching.

The 24 people sat in four rows, which quietly reminded the teachers on the stage that they could hear it.

Professor Zhai Yang raised his eyebrows and said with a smile: "It seems that Song Hao may not be good at memory, so copy the contents of the laws of thermodynamics and basic laws by hand ten times to strengthen your memory, and give it to me before class next week. is that OK?"

Song Hao was crying, and nodded reluctantly, "No, no problem."

"Then sit down." After Professor Zhai Yang finished speaking, his eyes narrowed. The movement of someone just now was more conspicuous.

"Student Song Hao has been looking at Chen Pingan just now. It seems that Chen Pingan should know it well, so let's answer this question."

Song Hao, who looked like his chrysanthemum had been exploded just now, suddenly turned from sadness to joy, gloated at Chen Ping'an, grinned silently, and even winked.

Looking at the bitch Song Hao, Chen Pingan's mouth twitched, his face calmly answered the question, and he stomped on the bitch next to him calmly.

"The essence of the first law of thermodynamics is the law of energy conservation and transformation."

Song Hao was stepped on, and made a "hissing" sound, with pain on his face, he didn't dare to hide.

Professor Zhai Yang nodded, and said in agreement: "The answer is good. It seems that Chen Ping'an has a review after returning, so I will help strengthen it."

"Then tell me about the second and third laws of thermodynamics."

Chen Ping's expression didn't change, he just paused for a few seconds, as if recalling.

"The second law of thermodynamics reveals the direction and limits of macroscopic processes..."

There was almost no pause, and the question was answered completely in one go.

I thought it was over, but Professor Zhai Yang smiled and spoke again.

"Not bad, then come up and write down the formulas of enthalpy change and thermochemical equation. I believe this should not be a big problem for Chen Pingan, right?"

Chen Pingan touched his nose and walked directly to the podium.

Pick up the chalk and write in a swish.

【Enthalpy change】

【△H=H tense-H final state=△U+pV】

【Thermochemical equation】

【2H(g)+O2=2HO(g)】

Just finished writing, the bell rang for the end of get out of class.

Professor Zhai Yang looked at the content on the blackboard and applauded lightly.

"Student Chen Ping'an's writing is very correct. Everyone should learn a lot from Chen Ping'an. That's the end of today's class. In the next class, we will talk about acid-base balance. Students remember to spend some time doing more previews these days There are homework and review of these two lessons, let's dismiss the class."

After the voice fell, the students who were sitting upright just now packed up their textbooks and rushed out in a swarm.

Professor Zhai Yang looked at the professor who disappeared in a flash, and cursed with a smile.

"Are these children a monkey?"

Outside the classroom, a group of departed students were still discussing Professor Zhai Yang.

"It's not that I said that Professor Zhai's class is the most frightening among all the teachers in our school. As long as he is a little off, he will call and answer questions." A student complained.

"That's right, but the instructors in our college are all very powerful. Professor Liang Yiqing of Semiconductors (has been hired as a full professor), and Professor Ren of the Optical Core Research Center, all of them are better than Professor Zhai. Much better!" Song Hao pouted and said, perhaps because he was a little embarrassed in class just now.

Chen Ping frowned slightly, and couldn't help interrupting Song Hao's words.

"Old Song, you are a bit prejudiced, Professor Zhai is a big name in the domestic chemical industry!"

"What, I have a reason."

Song Hao glanced at Chen Pingan with some trepidation, and said, "The traditional top four in China's chemical industry are: Peking University, Nankai University, South University, and Jilin University. Jida University alone has three state key laboratories in the School of Chemistry. Although chemistry is from Ludao University Its ace major, but it is only in the top ten in China, it is completely incomparable!"

Chen Ping just shook his head, "What you said is the strength of the school's departments, which is correct in theory, but when it comes to personal strength, Professor Zhai Yang was recruited by the president of Ludao University at the Massachusetts Institute of Technology, and he is well-known in China. , The status is very strong, even known as the North Huang Nanzhai of chemistry, No.1 in South Chemistry!"

Listening to Chen Ping'an's explanation, Song Hao and others were dumbfounded. Is Professor Zhai Yang, who usually gives lectures without any airs, so powerful?
But the Di Yang himself that Chen Pingan was talking about had just walked out of the classroom.

Leaving the teaching building on foot, the spirits of the students passing by on the campus road are far more vigorous than when he first came to Guanghua University.

When Zhai Yang thought of the students in the class just now, especially the student named Chen Pingan, he was filled with emotion.

Another pair of students at Ludao University.

Can't help sighing: "Young people today are really amazing!"

The Department of Chemistry at Ludao University was established in 1923. During the major adjustments in the disciplines in the 50s, it did not hurt the lifeline of the Institute of Chemistry. Therefore, Ludao University’s chemistry is quite powerful now. Ranked 8th in the ranking, it is also an A-level subject.

However, there is a saying in Ludao University called: School of Economics, School of Management, and other schools.

From this, one can imagine how strong the economics and management of Ludao University are.

Even if it is the eighth chemistry, its status in the school is still a bit embarrassing. Among other things, the tiankeng majors such as biochemical and environmental materials are all red card majors for employment, and the eighth is useless!
Don't listen to some people bragging about the wide range of careers in chemistry, but in fact they usually go to research institutes, but most of the research institutes start as graduate students, even if they are undergraduates in the Department of Chemistry at Ludao University, most of them change careers.

When the 19th chemistry department graduated, there were a total of 217 masters and Ph. D. students, only 125 had places to go, and the rest were unemployed. This is Ludao University, the eighth 985 university in the chemistry discipline, and the chemistry majors of other ordinary universities... Think about it. knew.

This is where students majoring in biochemical and environmental materials are forced to either study for a Ph.D. or change careers.

In addition, the Department of Chemistry at Lulu University can change majors, which has caused many undergraduates to study hard in order to be able to change majors and escape from Tiankeng.

Here at Guanghua College, perhaps because of the unique education system, students don't have much opinion on majors. After all, they only choose the direction of follow-up research in the sophomore year, and they are more pure in learning.

And he found that among the 24 students, when it comes to talent...

"Principal Chen is really amazing!"

Thinking of this, Professor Zhai Yang couldn't help but look at Guanghua Building, the most prominent and spectacular building on campus, with admiration.

The 87 students in the experimental class of Guanghua College are undoubtedly the gold that was scoured by the big waves. Compared with the students of Ludao University, the IQ of these students is not inferior in the slightest. The problem.

In a university with 2 people, no matter how rubbish it is, it is normal for dozens of good seedlings to appear.

leaving the car.

Di Yang glanced at the final silhouette of Guanghua University through the rearview mirror, and a thought came to him.

He smiled lightly, even he himself felt a little ridiculous.

"Maybe one day in the future, it is not impossible for Guanghua University to surpass Luda..."

At this moment, the phone rang.

The Bluetooth headset is connected.

"Principal Zhang, what's the matter?"

The voice of the president of Ludao University Zhang Yue's ridicule sounded.

"Professor Zhai, you should have finished your class with Guanghua by now, how do you feel?"

"Do you feel it? I feel pretty good." After thinking about it, Zhai Yang said with a smile without hiding it.

Principal Zhang smiled lightly and said, "Oh? That's just right. I really want to communicate with Professor Zhai about Guanghua University. I don't know when is the most convenient time?"

Di Yang glanced at his watch and said directly, "Just now, I just want to go to the laboratory, and then I'll see you, Principal Zhang."

"Hahaha, okay, then I will prepare some tea and wait for Professor Zhai's arrival."

The phone hangs up.

Di Yang's eyes turned slightly, and the corners of his mouth raised slightly.

"I probably know why."

Next chapter at 10pm.

　Two of my old friends got married today.

　　One is Nobi Nobita, and the other is Minamoto Shizuka.

　　I went to watch "Doraemon: Walk With Me 2" in the afternoon. I was so touched. Nobita and Shizuka finally got married!
　　Every time I watch "Doraemon", I feel that the Nobita in it seems to be me.When I was a child, I was also stupid, always being bullied, crying a lot, and wearing round-rimmed glasses.

　　The only difference is that I don’t have Doraemon (╥﹏╥)
　　Nobita, you must be happy! ! !
