Xueba, I beg you to go and escort him quickly!

There is a gap between them!

Comparing the answers to all the questions correctly, and the need to master everything and ask questions in a targeted manner, it is like a child and an adult.

Children only eat, drink, and drink. While ensuring that children eat, drink, and drink, adults need to further distinguish what to eat and drink for three meals a day, what to eat and drink, and what not to eat and drink.

This is the most intuitive!

So if you can ask questions, you must be able to answer all the questions above!

But if you can answer questions, basically you can't ask questions!

Fang Zhonggui looked at Xu Heng with shock in his eyes.

Dean Nie nodded, looking at Xu Heng, he always felt a little strange.

After going to the research institute, he always felt that Xu Heng was a different person.

"I always feel that he is diligent again! I can't say the specifics."

Fang Zhonggui laughed, "Maybe it's because I still don't want to admit Xu Heng's excellence! Oh, no, it's because he's too good that we can't end it for a while!"

Dean Nie sighed helplessly, that was the only way to go.

Xu Heng looked at the leisurely Dean Nie and Fang Zhonggui, "Come and help me! I'm not an old sow giving birth to piglets, but a litter!"

"Give me a few minutes to think about it anyway!"

"Two professors, don't worry!"

"Dean Nie, Professor Fang, help me too!"

Dean Nie and Fang Zhonggui smiled, "How many minutes do you need?"

Geek!

Xu Heng had black lines on his face, "This is boring! You two!"

Dean Nie shrugged, "Student Xu Heng, you said the few minutes yourself!"

Xu Heng felt like he dug a hole for himself.

He didn't expect that these people actually have this side!

He dared to bet that these four would never behave like this in front of others.

Only to myself!

In desperation, Xu Heng asked a question for each of them...

The two professors had seen it, and gave Xu Heng a thumbs up, "It's really productive!"

Xu Hengsheng has nothing to love, "Please let me go!"

After finally coming out of the professor's office, Xu Heng had just breathed out, when on the other side of the corridor, many people were looking at him.

Some of them were still holding their mobile phones, and seemed to be sending some news.

suddenly!

"Ding Ding Ding!"

Xu Heng's cell phone rang.

He took out his mobile phone, and there were many messages from @自己.

Finish the calf!

It must be the group of Peking University students in front of me who are @自己 in the group, wanting to make sure that what they see is me.

"Um... Hello, I'm Xu Heng!"

"You have also seen that I just came out of the office, something really happened!"

This group of people come up!

To Xu Heng, they are both curious and respectful.

"Student Xu Heng? Hello, hello, I'm Wang Hanshan from the group!"

"Hi, I'm from the group..."

"Hello,……"

"..."

A group of people followed and introduced themselves.

They talked as they walked.

Xu Heng, "By the way, where are you taking me?"

Everyone, "Canteen!"

Only then did Xu Heng tell Dean Nie, "I'm going to the cafeteria! Dean Nie! Your students from Peking University are too enthusiastic, and the hospitality is hard to refuse!"

Dean Nie, "Okay! Before you go back to the hotel, contact me and I'll see you off."

Xu Heng, "Thank you, Dean."

Surrounded by a group of Peking University students, Xu Heng went to the canteen of Peking University.

A group of people mighty, somewhat spectacular.

Xu Heng, "Eh... You guys, this, I've seen you! So..."

Meeting fans for the first time!

Xu Heng has no experience!

But look at the excited expressions of this group of people.

Xu Heng felt that it was necessary to show his hand.

It's still the same words.

people!

You have to witness it with your own eyes to be reconciled!

At the same time, in order to pass the embarrassing time, Xu Heng said, "Why don't you play some questions!"

"Which one of you will arrange a representative, let's brush up the questions?"

When Xu Heng said that, he played into the hearts of everyone.

Wang Hanshan, "I brought a pen and paper! Senior He has a question!"

"Senior He, you should be our representative!"

After all, he is the senior of Yuanpei College, and his strength is recognized by everyone present!

He Xuezhang sat down and faced Xu Heng.

With his and Xu Heng's knowledge and achievements, it is impossible for two people to look at each other's answers when they are doing the same problem!

As for He Xuezhang's question, he naturally didn't know the answer in advance!

He hasn't had time to look at it yet.

He still has this most basic quality!

Everyone also trusted He Xuezhang.

As a student of Yuanpei College, he still has this reputation and prestige.

Wang Hanshan distributed pens and paper to the two.

He Xuezhang took a deep breath and picked up the pen.

As for Xu Heng, he is confident.

　　He could do mental arithmetic before, not to mention getting an SSS rating!

"let's start!"

Right under everyone's gaze.

He Xuezhang grabbed the pen and paper nervously, but Xu Heng didn't lift his hand.

topic:

There is 2mol of helium in the cylinder, the initial temperature is 27°C, and the volume is 20L. First expand the helium at constant pressure until the volume doubles, and then expand adiabatically until it returns to the initial temperature. If helium is regarded as an ideal gas, then helium What is the change in internal energy of ?What is the total work done by helium?

This question is about the first law of heat.

Xu Heng and He Xuezhang answered almost at the same time, "The internal energy remains unchanged, so it is 0."

He Xuezhang, "As for the President..."

Xu Heng, "12465."

soon!And it's the correct answer!

Everyone's eyes are bright!

But for such a topic, they all know it, and the gap of a few seconds is nothing at all.

continue!

topic:

A cube with volume V and mass m0 is moving with speed v relative to observer A along a certain edge direction, what is the density measured by observer A?

He Xuezhang murmured, "The examination room of this question is to investigate the problem of mass enlargement and length shortening in the theory of relativity."

Afterwards, he began to calculate on the straw paper.

At this time, Xu Heng said directly, "ρ=m0/(v(1-v2/c2)."

He Xuezhang's pen, which was calculating, suddenly stopped.

He couldn't help murmuring, "No wonder Xu Heng can give Professor Fang and them questions in the office!"

The sound is obviously very small!

But it was heard by the students around me.

"What! Senior He, you actually said that Xu Heng was writing questions for Professor Fang and the others in the office! What's going on here?".

Chapter 178

"Senior He, what you just said is that Xu Heng is giving questions to several professors, right?"

Brush the floor!

All eyes focused on He Xuezhang, and then suddenly looked at Xu Heng.

"Student Xu Heng, is it true?"

Xu Heng immediately explained, "I didn't give them a question, I did their question before, and now I'm giving it back to them!"

"The few difficult questions in the group, I thought they were their usual questions, but after seeing them, I realized that these questions were prepared for the graduate students!"

"So I helped them come up with the questions, which is considered a kindness."

Having said that, the shock in these people's hearts eased a little.

"But it's still shocking!" Wang Hanshan's heart trembled, and he stared at Xu Heng, "Student Xu Heng, you are already at the level of a professor! Do you know that?"

I know!

Professor level is nothing!

You should call me a physicist.

Xu Heng is still very self-aware of himself.

After all, his SSS reward is not fake.

But Xu Heng just smiled slightly.

"Stop talking about this, senior, let's continue!"
