"Little Xuan, how much of the content in this' Chemistry 'book is true ~? Why do I feel like it's a little mysterious ~? "
After the meal, they didn't leave. Instead, they stayed in the main hall and chatted while drinking tea. Wang Ji picked up a book from the table next to him, pointed at the book and asked Li Zexuan.
It's worth mentioning that Wang Ji drank a lot of Drunken Immortal at noon. At this moment, only his cheeks were red and he wasn't drunk. Li Zexuan admired his alcohol tolerance from the bottom of his heart.
"This' Chemistry 'book, I can guarantee that it's 100% true ~! Chemistry is about the study of transformations. If you just look at the book, you'll feel that it's a little mysterious ~! "
Li Zexuan laughed when he heard this. He was still very confident in the course of "Chemistry". In his previous life, he had been a chemistry class representative and was always at the top of the class in every exam. In this life, he had an abnormal spiritual force, so he was even more confident that he would not make any mistakes.
Wang Ji nodded thoughtfully. After a while, he asked tentatively, "This book's structure is really big. It's really rare in the world. Although I didn't have time to read it, based on the first half of the book, doesn't it mean that all substances in the world can be transformed into each other ~?"
Li Zexuan was slightly stunned. He didn't expect that Wang Ji, this "Old Urchin", would be interested in 'Chemistry'. He thought for a while and replied,
"If it's based on the transformation between elements, Mr. Wang's theory is correct ~! But sometimes we have to consider reality because many chemical reactions have very strict requirements for external conditions. For example, temperature, catalyst, etc. If you don't meet certain conditions, even if you put two substances together, they won't have a chemical reaction, let alone complete the transformation between substances ~! "
Wang Ji frowned and said in surprise, "This little Chemistry actually has so many tricks ~?"
Li Zexuan laughed and said, "Of course ~! Strictly speaking, the content of this class covers everything in the world ~! You have to know that there are millions of substances in the world and there are even more chemical reactions between them ~! So there's a lot of knowledge in this ~! "
As Wang Ji listened, he pinched his chin and pondered seriously. After a while, he opened the book and pointed to a page.
"You used chemical symbols to represent many substances according to their elemental composition. Of course, I don't know if your representation is right or wrong, so I'll follow your thinking first. For example, in this chapter, you said that hydrogen can be burned in oxygen to produce water. According to what you said earlier, doesn't it mean that water can also be converted into hydrogen and oxygen under certain special conditions?"
Li Zexuan was really surprised this time. Wang Ji's way of thinking and his ability to draw inferences was really different from the capable people of this era! Moreover, how long had he been reading this book? How could he reach such a level? He had to admit that geniuses were geniuses. They learned things very quickly! Perhaps this person could really do it …
Thinking of this, Li Zexuan explained seriously, "Sir, you are right. Water can indeed be decomposed into oxygen and hydrogen. If you read further, you will see this in the later chapters! But now, I can also explain it to you seriously ~!
The so-called chemical change is the process of molecules being divided into atoms, and the atoms being recombined into new molecules. If you read the previous chapters, you will have a general understanding of the concept of molecules and atoms ~! Hydrogen and oxygen are both diatomic molecules. A water molecule is composed of three atoms. In comparison, hydrogen is more active chemically. It can be burned in oxygen. While releasing heat, it can produce more chemically stable water. You can calculate their ratio to be 2: 1: 2 according to the number of atoms between the three. In the process of the reaction, the number of atoms is conserved.
Just now, you asked how water can be converted into hydrogen and oxygen. This kid will also explain it to you ~! Previously, I said that when hydrogen is burned in oxygen, it releases heat and produces more chemically stable water. Now, if you want to turn chemically stable water into chemically active hydrogen and oxygen, we have to pay a certain amount of energy to promote this chemical reaction to proceed normally ~! What I want to tell you is that no matter when, energy is conserved ~! "
Wang Ji was startled. He seemed to have thought of something and muttered involuntarily, "Energy conservation, matter conservation, all things engender each other ~! This little chemistry actually contains the Heavenly Dao ~? "
In Wang Ji's life, he was an official and retired man. In order to achieve spiritual satisfaction, he studied Daoist culture very much. Moreover, his thoughts and some of his later works were deeply influenced by Daoist culture. At this moment, after listening to Li Zexuan's explanation, he suddenly thought of the Daoist ideology that all things were related to each other and the conservation of Yin and Yang. Wang Ji, who was originally very interested in Chemistry, felt that the door to a new world was opening to him. He wanted to understand this knowledge even more.
"Then, what kind of energy is needed to turn water into hydrogen and oxygen ~? Does it need to be heated ~? No, no, when we boil water, we don't see water turning into hydrogen and oxygen ~? "
After secretly sighing for a while, Wang Ji couldn't help but ask.
Li Zexuan was about to explain, but Yan Silu interrupted at this time. "Wang Wugong, you've just read the book for less than two hours, and you're already starting to have ideas ~? Don't pretend to know when you don't and make a fool of yourself in front of the juniors ~! "
Li Zexuan talked about chemistry with Wang Ji, but he, Li Gang, and Mo Huai were confused and didn't understand half of it. After being depressed for a long time, he finally couldn't help but ask.
"Pfft ~!"
Wang Ji curled his lips and sneered. "You, Yan Konggui, can't do it, but it doesn't mean that I, Wang Ji, can't do it ~! I've long said that I, Wang Ji, am better than you. I'm better at learning everything fast, but you didn't believe it ~! "
"Wang Wugong ~! How arrogant of you ~! You only know some superficial knowledge, how can you brag here ~? Do you have any shame ~? "
How could Yan Silu stand such humiliation, so he said angrily.
Wang Ji retorted, "A little ~? It's indeed a little, but I can understand a little in less than two hours. Doesn't this mean that I'm a faster learner than you ~? Now, Yan Konggui, do you dare to say that I, Wang Ji, am not worth a monthly salary of five buckets of wine ~? "
Yan Silu said indignantly, "Yanhuang College is going to be the elite college of the Tang Dynasty in the future. How can I ask you, a teacher who only knows a little, to mislead the students ~? Not to mention five buckets of wine, in my opinion, even one buckets of wine is too much for you ~! "
"Hmph ~! I only know a little now, but it doesn't mean that I'll be like this when school starts ~! Yan Konggui, do you dare to make a bet with me ~? "
