saturation concentration

Sui Cannong wants to give Ji Ling the most sense of security, and he doesn't care about other people's opinions, he just wants to tell others that Ji Ling is his partner.

Ji Ling was a little dazed at first, but soon his eyes became firm.He hummed lightly, and then took Sui Cannong's hand back.

Sui Cannong could clearly hear Thomas gasping, but they stopped caring about other people's gazes, and after looking at each other for a few seconds, Sui Cannong smiled and said, "Just follow my rhythm. "

The lighting and atmosphere at the ball were very good, and the little hands and eyes were paired together, which was indeed very romantic.

Then within 5 minutes, Sui Cannong guessed the reason why Ji Ling never went to the ball.

The duration of a dance is actually only a few minutes, but during this period, Sui Cannong was stepped on by Ji Ling no less than twenty times.

Ji Ling's body was very stiff throughout the whole process, which is a typical case of limb incoordination.So Sui Cannong no longer forced him to dance, but pulled Ji Ling away from the crowd, and the two ate all the desserts provided in the venue.

In fact, after disclosing his relationship with Ji Ling, Sui Cannong received more kindness than he imagined.

Thomas became the number one supporter of their relationship, and when they ran into other teachers on campus, they would also send blessings to Sui Channong.

And falling in love with Ji Ling is actually a very interesting thing.

Teacher Xiao Ji's cultivation method is actually very simple. It only needs a little water, a little fertilizer, and a little light provided by a human named Sui Cannong.

Ji Ling is still obsessed with listing his long-term plans, and now his insistence on clocking in has become a "dating check-in list", and he will ask Sui Cannong to help him complete the clocking-in task.

Ji Ling said, "Can I go to the movies on weekends?"

So they went to watch a horror movie together on the weekend. It was the movie theater last time, or the rainbow popcorn package last time, but the mood of the two of them at this time was quite different.

The movie Ji Ling chose was a Thai horror movie, and the theme was a suicide case of a college girl. Before switching to it, Sui Cannong might immediately become highly vigilant and even start pinching someone.

But looking back now, Sui Cannong just felt helpless and funny.

During the movie watching, Ji Ling was so focused that she didn't even blink her eyes. Sui Cannong closed her eyes and covered her ears the whole time, just wanting to pass out.

Sui Cannong didn't notice much at all.

In fact, the movie-watching atmosphere was not too different from last time. Sui Cannong's fear was real, but it wasn't as serious as it appeared. He just wanted to find a reason to stick with Ji Ling.

Later, during the video, they secretly kissed.

Ji Ling ate a lot of popcorn. At the end of the show, Sui Cannong stared at the empty popcorn bucket and pondered for a moment, then asked, "Aren't you going to take pictures this time?"

Ji Ling shook his head.

"Because we can watch a movie every month in the future." Ji Ling said with hope, "I did some research, and this theater has a lot of movies scheduled, and next month there will be a re-screening of a niche Korean horror movie... "

Sui Cannong: "...I don't mind watching it once a month, but can we watch a different type of movie?"

May and June are the seasons of parting. The major exams for the students are basically over, and the graduation season is approaching.

Although Shirley and Cindy still have a year to graduate from high school, but because of their parents' job changes, the two little girls have to go back to Japan to continue their studies.

Although Sui Cannong always liked to bicker with the two of them, but now he was a little bit reluctant to part with these two little girls.He gave them the pot of small tomatoes they planted, and gave them two packets of vegetable seeds.

Shirley and Cindy also gave Sui Channong a key chain they wove by themselves, saying, "We also gave Teacher Ji a key chain of the same style and different colors."

Sui Cannong: "Huh?"

Shirley said: "So you and Teacher Ji must be well."

Sui Cannong: "...?"

Cindy said, "It's okay, we both already know."

Sui Cannong was numb: "No, no...how did you know?"

Shirley said: "Because you often visit each other's classrooms."

Sui Cannong naturally didn't believe their words, so Cindy hesitated and said, "Actually, it's because the two of us accidentally saw Teacher Ji's cell phone that day."

"His screen saver...uses your picture," she said.

After school, Ji Ling came to Sui Cannong's classroom to organize the flowers and plants.

Sui Cannong's classroom is chaotic and orderly, but the types of flowers and plants are too complicated. Ji Ling has a slight obsessive-compulsive disorder, and he always feels a little uncomfortable looking at it.

So today Ji Ling is going to help Sui Cannong tidy up a corner first.

Ji Ling first saw the pot used to hold the potted mushrooms, and found that there was still a label of "Mr. Ji" written by Sui Cannong himself on it.And on the pot of roses that I gave to Sui Cannong, there was still the slightly yellowed "Mr. Sui" sticky note.

Ji Ling couldn't help laughing.

When she stood up, Ji Ling saw two timid students standing behind her, they were unfamiliar faces, they should be freshmen who came recently, and they were holding two brand new chemistry books in their hands.

The student asked: "Ms. Sui, Mr. Thomas is not in the classroom. He said that if we have any questions, we can come to you directly."

Before Ji Ling could speak, the two students directly opened the textbook and said, "So can you explain to us, what does saturated mean here?"

Ji Ling would often come to Sui Cannong's classroom to drop by. These two are new freshmen, and they may not know that Ji Ling actually teaches physics. They probably mistook him for Sui Cannong himself.

Ji Ling hesitated for a moment, but still did not correct them.

Saturated means saturated. Ji Ling looked at their books and found that they were just some relatively simple basic chemical knowledge about solutions and solvents.

So Ji Ling also gave a relatively clear explanation: "The solution is composed of solvent and solute. When the temperature is constant and the solute cannot continue to dissolve in a certain amount of solvent, we will say that the solution is already saturated. , that is, the saturated mentioned here.”

Then Ji Ling watched helplessly as the student's expression changed from normal confusion to extreme confusion.

Ji Ling pursed her lips, hesitating how to change the words to make the students understand better, then she saw Sui Cannong walking in with the printed things.

Sui Cannong stared at Shang Ji Ling and asked blankly, "What's wrong?"

Ji Ling hesitated for a moment, then repeated the student's question, and Sui Cannong laughed along with it.

"Let's give a simple example first." Sui Cannong said to the students, "For example, if you really like a pair of sneakers, you only want this pair with all your heart and eyes, and you can't stand any other color or style. If so, then it means that your heart is filled to saturation by this pair of sneakers."

"If the salt water is saturated...you can understand that the water likes the current salt very much. Its heart has been filled with the current salt, so other salts cannot continue to dissolve in the water." Sui Cannong said with a smile, "And if I remember correctly, the saturation concentration of brine should be about 5.4 moles per liter. You can read the summary in the book first..."

Five minutes later, the two students showed a look of sudden realization. They thanked Sui Cannong and left the classroom together.

Sui Cannong cleaned up the things on the table and found that Ji Ling seemed to have finished watering the flowers, so he and Ji Ling started to walk towards the parking lot.

However, when he opened the car door, Sui Cannong found that Ji Ling seemed a little unhappy.

When Sui Cannong started the car, he heard Ji Ling say sullenly: "Actually, I also explained the meaning of saturation to them at that time, but they didn't understand my explanation."

Although Sui Cannong was not there, but he had a little idea of ​​the scene at that time, combined with Ji Ling's usual way of speaking, he vaguely guessed what happened at that time.

Sui Cannong didn't know whether to laugh or cry: "It doesn't matter, it's just a small point of knowledge."

Ji Ling was silent for a while, and then said: "Although we explain knowledge in different ways, what I said is very clear, why can't they understand what I said..."

Sui Can coughed heavily, and quickly changed the subject: "What do you want to eat tonight?"

Ji Ling paused for a moment, and was quickly distracted by Sui Cannong, saying, "...I want noodles, or noodle soup."

Sui Cannong thought about the ingredients left at home, and felt that he could make tomato noodle soup to eat, so he hummed and asked, "What drama do you want to watch when we have dinner today?"

Ji Ling thought for a while and said, "Today is Thursday, the blogger who fried yogurt rolls should be updated."

"Yes." Sui Cannong said, "Let's place a bet in advance, this time I bet he will fry five rolls of yogurt, how about you?"

Ji Ling said: "But I remember that in this month, five rolls have been speculated fourteen times, so this time I bet on four rolls."

Sui Cannong said: "Okay, it's a deal, no changes are allowed."

They were quiet for a while, and Sui Cannong drove the car into the community at the same time.

"Why didn't they understand my explanation?" Ji Ling was still a little worried, "And for the saturation concentration of salt water, temperature is also one of the very important variables, so the value you just mentioned is actually very wrong. precise--"

Sui Cannong parked the car firmly in the parking space, and then he took off his seat belt.

Ji Ling didn't say the second half of the sentence, because Sui Cannong turned his head and kissed him suddenly.

Ji Ling was pressed down on the seat by Sui Cannong, he was startled for a moment, then raised his face slightly after a while, and responded meekly to the kiss.

Their warm breath blended with each other.

"...Let me go, Mr. Ji." Sui Cannong got up after a while, and said in a hoarse voice, "Science is very complicated, and there are too many variables. No one can give an absolutely correct answer."

Ji Ling shook her head and said with a smile, "I know, I just—"

Before Ji Ling finished the second half of his sentence, Sui Cannong interrupted him."But there's one thing I'm sure of," he said.

The clouds outside the window are orange, the sunset is warm, and Sui Cannong's eyes are bright. He looks at Ji Ling with a firm and brilliant smile in his eyes.

"That is, no matter what temperature or condition," Sui Cannong said with a smile, "only one mole of Ji Ling is enough to reach Sui Cannong's saturation concentration."
