Chapter 104 The Pitfalls of Experimental Questions

After searching and stopping along the way, Wu Bin finally found Cui Shaodong by the window sill on the second floor.

"Here, here's one." Wu Bin pulled out a green arrow and handed it to Cui Shaodong.

"Don't you understand the basic truth that the person who ran out wanted to calm down?"

Cui Shaodong said that even though he said that, he still took the chewing gum.

"Just think that I am nosy." After Wu Bin finished speaking, he peeled off a green arrow and threw it into his mouth.

So the two of them just looked at the playground and chewed gum.

"Aren't you here to comfort me? Why don't you say something?" After a few minutes, Cui Shaodong, who was almost out of chewing gum, finally couldn't help but speak first.

"You want to hear me say, 'It's okay. You can take the exam again next time. One exam means you won't talk about anything like this?'" Wu Bin smiled.

"Alas..." Cui Shaodong sighed again after hearing this, and said, "I never learned anything and I actually got stuck on mechanics questions."

"Question 7?"

"More than that." Cui Shaodong shook his head.

Wu Bin said nothing.

"What about you?" Cui Shaodong looked at Wu Bin.

"It didn't bother me at all." Wu Bin answered honestly.

"Awesome." Cui Shaodong said and tried to blow a bubble with chewing gum, but failed.

"Maybe I haven't worked hard enough, not as hard as you." Cui Shaodong looked into the distance and couldn't help but sigh.

"Actually, I don't work very hard, I just like it. Physics is very interesting, isn't it?" Wu Bin said with a smile.

"Is it interesting?" Cui Shaodong looked a little confused, "Maybe..."

Then Cui Shaodong was silent for a long time before finally raising his head and saying, "Let's go back to eat."

When they returned to the cafeteria, everyone saw Cui Shaodong returning and didn't say much. They just continued to eat with their heads down. But in Wu Bin's opinion, it looked more like they were pounding the rice, then stirring it, and repeating this action several times.

"Where is Li Yan?" Wei Tianshuo suddenly pulled Wu Bin and asked quietly.

Wu Bin looked confused, shook his head and said, "I didn't see him."

"It's strange. He just said he wanted to go find Cui Shaodong with you."

After saying this, Wei Tianshuo suddenly felt a sudden realization, and so did Wu Bin, so the two of them tacitly continued to eat.

Finally, when it was time to gather, Li Yan ran back and said with a smile that Yizhong was too big and he got lost after chasing it.

At this time, naturally no one would worry about whether Li Yan's words were true or not, and they just silently got on the bus back to the hotel.

The students who returned to the hotel originally wanted to go back to their rooms and take a good nap before talking, but Wei Tianshuo reminded them that they had to go to the banquet hall to draw numbers to decide the groups for tomorrow's experimental exam.

Sitting in rows in the banquet hall, Li Yan, who probably couldn't stand the atmosphere in the team, suddenly patted Wu Bin and said, "I'm afraid Wu Shen will stand out in the experimental test tomorrow."

Others nodded after listening to Li Yan's words. In the training class, they had experienced Wu Bin's ability in doing experimental questions, and his accuracy was astonishingly high.

"You're welcome, Li Shen, your level is not bad either."

At this moment, Zhao Kehan ​​suddenly said: "Everyone says that the competition is a theoretical test that determines the outcome, but I think the experimental questions are the key to getting points. There are too many small details. If you are not careful, you will lose 3 or 4 points, like Wu Shen would never make such a mistake."

"I said, the exam is tomorrow. Is it really okay for you to be so supportive of me now?" Wu Bin looked helpless.

"After all, your experimental questions are recognized as excellent." Jiang Hang, who had been in a state of "meditation" along the way, suddenly spoke.

"Yes, the strong are not afraid of breasts." Li Yan nodded, and then added: "And what Zhao Shen said is right. The experimental questions seem to give points, but many people suffer from them. I have heard that before Let me share with you some jokes from several years ago.”

"But there is no guarantee of authenticity." After Li Yan finished speaking, he paused and began to speak.

"There was an experimental question the year before last called "Measuring the Curie point of an unknown material."

Wu Bin nodded as he listened. Some materials will undergo a phase change and lose their ferromagnetic properties when they rise to a certain temperature. This temperature is called the Curie point of the material. It can be said to be a test point that is often used in questions.

"And the committee members of that session were very considerate~" Li Yan said in a long voice, "There are quite a lot of equipment provided, including a basin of water and an alcohol lamp, which you can choose by yourself."

Hearing Li Yan's emphasis, Wu Bin could almost imagine where the pit was.

"The experiment lasted two hours, so after reading the test questions, the students set up the experimental device and started to boil the water. But after the water boiled completely, the students doing the experiment were dumbfounded because the Curie material given in the experiment The point is greater than 100 degrees Celsius, so even if you boil the water dry, you still can’t find its Curie point!”

Li Yan shook his head when he said this, "The correct experimental method should be to use an alcohol lamp to heat the material, and when it undergoes a phase change, quickly put it into the "ice melting heat" thermal insulation device. According to Its specific heat capacity is used to calculate its Curie point..."

"So the alcohol lamp and the water basin were just used to mislead the students, right?" Zhao Kehan ​​couldn't help but feel goosebumps on his back. If he made the wrong choice, there would definitely not be enough time left for the second experiment.

"Yes, that's right, so everyone should take this as a warning." Li Yan nodded seriously.

My post-operative recovery is pretty good. My nose has stopped bleeding in the afternoon and the fever has gradually subsided. So I’m going to give it a try while I’m still energetic. If everything goes well after a good sleep today, I’ll be discharged from the hospital tomorrow. Thank you very much for your blessings. I’m very touched. , I will definitely write better content to repay everyone!
