Xueba's Sea of ​​Stars

Chapter 104 Pitfalls of Experimental Questions

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.

"The people who ran out wanted to calm down, don't you understand the basic truth?"

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

"Just pretend that I like to meddle in other people's business." After Wu Bin finished speaking, he also peeled off a green arrow and threw it into his mouth.

So the two of them just looked at the playground, chewing gum.

"Didn't you come to comfort me? You should say something." A few minutes later, Cui Shaodong, who was about to chew his chewing gum, finally couldn't help but speak first.

"You want to hear me say, 'It's okay, take the exam next time, what does a test mean you don't talk about it?'" Wu Bin smiled.

"Alas..." Cui Shaodong sighed again after hearing this, and said, "I never learned that I can break down on mechanics problems."

"Question seven?"

"Not only." Cui Shaodong shook his head.

Wu Bin didn't speak.

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

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

"Excellent." Cui Shaodong said trying 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 feeling.

"Actually, I didn't work hard. I just like it. Physics is very interesting, isn't it?" Wu Bin laughed.

"Interesting?" Cui Shaodong's expression was a little confused, "Maybe..."

Then Cui Shaodong was silent for a long time, finally raised his head and said: "Let's go, go back to eat."

When they returned to the cafeteria, everyone didn't say much when they saw Cui Shaodong who had returned. They just continued to eat with their heads down, but in Wu Bin's view, it was more like they were smashing the rice, stirring it and repeating this action several times.

"Where's Li Yan?" Wei Tianshuo suddenly grabbed Wu Bin and asked in a low voice.

Wu Bin, on the other hand, looked blank, shook his head and said, "I didn't see him."

"Strange, he said just now that he wanted to go find Cui Shaodong with you."

After saying this, Wei Tianshuo suddenly had a feeling of enlightenment, and Wu Bin did the same, 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 lost his way after chasing it.

Naturally, no one would worry about whether Li Yan's words were true at this time, but they just got on the bus back to the hotel silently.

The contestants who returned to the hotel originally wanted to go back to the room and have a good sleep, but Wei Tianshuo reminded them that they had to go to the banquet hall to draw numbers to decide the grouping of tomorrow's experimental exam.

Sitting in a row in the banquet hall, Li Yan, who probably couldn't stand the atmosphere in the team, suddenly patted Wu Bin and said, "God Wu will stand out in the lab test tomorrow."

The others also nodded after listening to Li Yan's words. During the intensive training class, they had learned that Wu Bin was good at doing the experimental questions, and the accuracy was astonishingly high.

"Li Shen is being polite, your level is not bad."

At this moment Zhao Kehan ​​said suddenly: "It is said that the competition is a theoretical test to determine the winner, but I think the experimental questions are the key to gaining points. There are too many small details. If you are not careful, 3 or 4 points will be lost. Like God Wu would not make such a mistake."

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

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

"Yes, the strong are not afraid of milk." Li Yan nodded, and then said: "And what Zhao Shen said is right, the experimental questions seem to give points, but there are also many people who suffer from it. Let me share with you a few jokes."

"But there is no guarantee of authenticity." Li Yan paused and began to speak.

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

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 'caring~'" Li Yan dragged on here, "There are quite a lot of equipment given, including a basin of water and an alcohol lamp. You can choose by yourself."

Hearing Li Yan's emphasis, Wu Bin can almost imagine where the pit is.

"The experiment lasted for two hours, so the students who read the test questions set up the experimental device and started to boil the water, but after the water boiled completely, the students who did the experiment were dumbfounded, because the materials given in the experiment Curie The Curie point is greater than 100 degrees Celsius, so even if you boil the water dry, you will not be able to find its Curie point!"

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

"So the alcohol lamp and water basin are completely used to mislead the students, right?" Zhao Kehan ​​couldn't help getting goosebumps on his back. If he made a wrong choice, the time left must not be enough for the second experiment.

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

　The postoperative recovery is not bad, the nose is no longer bleeding in the afternoon, and the heat is gradually receding, so I quickly slapped it while I was energetic. If I sleep well today, I will be discharged from the hospital tomorrow. Thank you very much for your blessings, I am very touched , will definitely write better content to repay everyone!
