Curiosity kills cats, and the last thing young people lack is curiosity. The sudden construction of the research institute www.biquge.info the Pen, the Tower of Babel, and the soldiers of the People's Liberation Army on duty, all these changes aroused the infinite curiosity of Luo Tian's classmates.

"When will there be more garrison patrols in our school?" "I don't know, it should be during the winter vacation."

"When did the research institute of our physics department expand?" "Let's go winter vacation"

"Who knows what's going on at our school this winter break?" "I don't know, I heard that it was an explosion in the high-energy physics laboratory, and the state funded it to rebuild it." "It's going to be done too fast! And so much more. ”

…………

As soon as class ended, Luo Tian heard all kinds of discussions from his classmates. For Luo Tian, these discussions were meaningless, and he put away the book in his hand and hurried to the next classroom with a glass of water.

Out of the classroom, Luo Tian followed his classmates directly through the corridor and came to the other side of the corridor. The layout of all the large classrooms in the west building of the Department of Physics is basically the same and symmetrically distributed. The classroom of Thermal Studies is just across from the classroom where I took the high math class, and the layout of the interior is exactly the same.

There is basically no exclusive classroom in the university, and when I came to the door of the classroom, the students who had been in the classroom in the previous class were walking outside, and Luo Tian and they were waiting outside. Some people squeezed in against the flow of people, intending to get in and get a good seat. Luo Tian didn't care, and the middle seat in the first row was basically no one to grab with him.

Ten minutes between classes passed quickly, and at 10:5, it was normally time to start class, but Teacher Rexue was still in the classroom. The teacher is late for class, and it is not uncommon for him to be late, but he may have been delayed by something, and he should have come after a while.

Five minutes, ten minutes, and still no trace of the teacher. Many of you are a little impatient, "Why hasn't the teacher come yet?" and "Is this class still being held?" "The class representative is looking for the teacher", the classroom was filled with whispered discussions.

The representative of the heat class is a tall boy named Wang Peng, who is also Luo Tian's roommate. Wang Peng usually loves fitness, and he is very strong, and his physical fitness even exceeds that of most sports students. "Everyone be quiet, read the book by yourself first, and I'll go find the teacher."

Teachers of each subject will leave their phone numbers and email addresses for students to contact at the beginning of the first class. Wang Peng first took out his mobile phone and tried to dial the teacher's number, "I'm sorry, the phone you dialed has been turned off, please dial again later......"

"Shut down?" Wang Peng didn't expect that the teacher, who usually turns on the phone 24 hours a day, would turn off the phone, "I can only go to the office for a trip." The thermal office is on the fifth floor of the department building, and they are now taking classes on the second floor, not far away. Wang Peng didn't climb the stairs, in order to be fast, he took the elevator to the fifth floor.

There are also classrooms on the fifth floor, but the classrooms are at both ends, and there are still some rooms in between. Some of these rooms are study halls, and some are teachers' offices. In a group of thermal studies, Wang Peng often comes to send homework, holding test questions and the like, which is very familiar. The office of the Thermal Science Group is relatively large, and there are six teachers working here.

In the office, the three teachers were discussing about Wang Fang, "Sister Wang didn't come to work today, and she didn't ask for leave, she has classes today, should we substitute for her two classes?" "Let's go, it's been almost ten minutes since class, and the student should be in a hurry," "I'll go to class for her today." "Okay, I'll try to contact Sister Wang again."

"Dangdangdang" Wang Peng knocked on the door first, "Come in." Wang Peng looked at it, and his teacher was not there, "Teacher, Teacher Wang Fang didn't go to teach us just now, do you know where she went?" "Oh, you Teacher Wang may have something to do today, I'll teach you a lesson for her. You go back first, and I'll go right away. "Oh, thank you, teacher, I'll go back first."

Wang Peng took the elevator back to the classroom, "How is it?" "Everyone is quiet first, Mr. Wang can't come today because of something. There will be other teachers teaching you in a while, so let's wait a minute." After Wang Peng finished speaking, he returned to his seat and sat down, and as soon as he sat down, the substitute teacher pushed the door in.

"Students, if you Teacher Wang didn't come today, I will teach you a lesson. My surname is Li, you can call me Mr. Li. Without further ado, classes have officially begun. "The new substitute teacher is younger than the original teacher, and he is only thirty-five years old, which is the youngest teacher in the thermal group.

For Luo Tian, it doesn't matter which teacher comes to class. He was reading a book while pouring solidified mental power into the memory world in his mind, and it was too easy for him to be distracted. The surrounding classmates had long been accustomed to Luo Tian's behavior, including the squad leader sitting next to him, who didn't care about Luo Tian.

"The girl in the middle of the first row, get up and answer this question", Li Ling had already seen that Luo Tian was there and did not listen to the class, although she was reading a book and did not make trouble, she still lit Luo Tian up. As soon as Li Ling finished speaking, the entire classroom suddenly erupted in a burst of laughter, "Ha...... Haha......, girl...... Haha", both classes laughed.

Seeing the laughing students below, Li Ling was a little confused, she didn't know what was funny about her words just now. Luo Tian also wanted to laugh a little, and there was another person who regarded himself as a girl. He put down the book in his hand and stood up, "Teacher, I'm a man." Luo Tian's speech speed was very slow, and his voice was clear and sweet.

Luo Tian's voice is also an existence that makes the girls in the class jealous, clear and sweet, very good, and many girls are ashamed of themselves. Of course, this is Luo Tian's original voice, and he can also use his telekinesis to control his vocal cords and make a deep male voice. Recently, Luo Tian has been trying his best to control his use of telekinesis, so he no longer disguises his voice.

"Wow, I heard Luo Tian's anti-heaven voice again, I really can't stand it!" There was another slight commotion in the classroom. "Male?" Li Ling felt that her three views had been refreshed, "You are the Luo Tian of Class 6?" Li Ling remembered the beautiful little boy Wang Fang mentioned in the office.

"Oh, it's the teacher's fault, then you answer the question on the blackboard", Li Ling found a staircase for herself.

Luo Tian looked at the blackboard, there was a chart analysis question on the blackboard, and after a little look, he had the answer.

"Equal molar specific heat Cvm = 3R/2, Dunya molar specific heat Cpm = 5R/2

Special point constant temperature: Ta=Pa*Va/(Nmol*R), Tb=Pb*Vb/(Nmo*R), Tc=Pc*Vc/(Nmol*R), and Nmol is the mole amount of gas.

The increase of internal energy: AB: Nmol*Cvm*(Tb-Ta)=3*(Pb*Vb-Pa*Va)/2;BC:Nmol*Cvm*(Tc-Tb)=3*(Pc*Vc-Pb*Vb)/2------ are added to get all.

External work: AB: Nmol*R*(Tb-Ta)=(Pb*Vb-Pa*Va), BC:-Nmol*Cvm*(Tc-Tb)=-3*(Pc*Vc-Pb*Vb)/2------ are added to obtain all.

Absorbed heat: AB: Nmol*Cpm*(Tb-Ta)=5*(Pb*Vb-Pa*Va)/2;BC: 0------ add to get all. ”

Luo Tian had never seen this question, but he had just glanced at it. For Luo Tian, a glance is enough.

"Sit down," Li Ling didn't expect this little boy named Luo Tian to be really so powerful, although Wang Fang usually praised Luo Tian in the office, but it was still so shocking to witness it in person.
