Chapter 210: Gold

Management is a huge topic, it can't be seen or touched, but neither enterprises nor countries can ignore its existence. If Qiming wants to continue to exist, he has to think about it.

Chen Du used to only concentrate on living his own life, and he didn't have much experience in these things, and when he heard Dong Junwei talk about the Tao, he naturally wouldn't object.

In the days when we go out, because of the shortage of manpower, there will definitely be a break in construction, in this case, to do some spiritual civilization and rules and regulations construction, is also a way.

Two days later.

The heat storage time for the three metals is finally complete.

The final data is:

Aluminum: 7 hours;

Stainless steel: 26 hours;

Copper: 46 hours.

Obviously, using copper as a heat source is better than stainless steel.

There are a lot of wires found in the second cardboard box, and copper has no advantage as a building material, so it is just right for this.

"What kind of pattern can we see with this kind of data?"

Chen Du only knows the density of the specific values of those attributes, and it is obviously impossible for him to summarize any laws.

"I think of one." Tang Jing said.

"What?"

"According to the current ratio, the most consistent attribute should be liveliness."

"Metallic liveliness?" Chen Du was stunned.

"Yes." Tang Jing nodded.

"But why is liveliness related to the heat storage capacity of the material?" Chen Du asked again.

"It's hard to say, the liveliness of metals, which refers to the tendency to lose electrons in aqueous solutions to form metal cations, is a thermodynamic concept." Tang Jing said: "If you have to say it, this is the connection, of course, even if there is no connection, the ability is such a thing, it is unreasonable, and all we can do is just summarize and summarize." ”

"I remember that the embodiment of liveliness should be ......" Chen Duan was stuck on that word for a while, unable to speak.

"Standard electrode potential." Tang Jing replied.

"Aluminum is the liveliest?"

"Yes of the three, but among all the metals, lithium should be the most active, that is, the kind of metal that makes batteries, I roughly calculated, lithium has a heat storage time of only 4.5 hours, and we need the least active kind."

"Which is the least lively?" He Ying Q&A.

"Kim." Tang Jing said.

"Gold?"

"That's right." Tang Jing said: "The heat storage time of gold, I calculated it to be 124 hours, if you guess well, its temperature ceiling will be higher, if it is used in the engine, it can be supplied for more than 80 hours, which is still calculated according to the current ability of the squad leader." ”

"But it's hard to find gold......"

"yes."

"And what about the worse ones?"

"Silver, more than 60 hours."

"It's not easy to find."

Dong Junwei suddenly said: "I know where there is gold. ”

"I know that too, bank vaults?" Chen Du smiled.

"I mean inside the school." Dong Junwei said.

"Also in the school?"

"Do you remember Teacher Qi Luo, who taught us geography in the first year of high school?" Dong Junwei asked.

"That beautiful Teacher Qi?" Zhu Hao said for the first time.

"Well, every time she comes to school, she brings her own jewelry on the way, but when it's time for class, she locks her jewelry in her desk." Dong Junwei recalled.

"Squad leader, how do you know?" Chen Du said curiously.

"She told me." Dong Junwei spread her hands.

"Why is Teacher Qi telling you this?" He Ying asked suspiciously.

"The last time I went to her office to help out, I complimented her on the beauty of her bracelets, and I talked about these things by the way." Dong Junwei remembered what happened in school before, and unconsciously smiled, and said: "As you know, students are not allowed to bring jewelry, but in fact, teachers do not encourage them in principle, but Teacher Qi is born with a love of beauty, so he used this compromise method." ”

"But isn't it safe to keep your jewelry in your desk?" Chen Du asked puzzled.

"The school is the safest, the office hallway is full of cameras, there are so many people coming and going, who will steal here?" Dong Junwei said: "Besides, it's just some ordinary gold jewelry, and my husband is very rich, so these things are probably similar to toys." ”

Chen Du couldn't imagine that the head of the class usually looked at Gao Leng, and his eyebrows would dance when he talked about the gossip and trivial matters of these teachers, and he couldn't help but laugh.

"When disaster struck, it was between the second period, and I guess the gold jewellery was probably still in my desk." Dong Junwei said.

"Then the next time you go out, look for it?" Chen Dudao.

"You can think about it."

Tang Jing said: "Anyway, where is Teacher Qi Luo's office?" ”

"The offices of the associate subject teachers are all in the administrative annex, and Mr. Qi is room 309 on the third floor." Dong Junwei said.

"In that case, our next goal is to get the car on and get a container of gold back." Chen Du said in a grand manner.

"I suggest the squad leader go along." Tang Jing said suddenly.

"Me?" Dong Junwei was stunned.

"Hmm." Tang Jing said: "Even if copper is used as a heat source, the use time of the vehicle will not exceed 20 hours at most, if there is no way to replenish the heat halfway, the engine will stop, so let the squad leader accompany you, you can improve efficiency, and the next time you have gold, you don't need it." ”

Although copper has a heat storage time of 46 hours, the temperature of the metal heat source gradually decreases over time, and the actual time that can be used by the engine is only 20 hours.

After Dong Junwei's heating, the metal has a characteristic of cooling.

That is, it has nothing to do with the surrounding environment.

It only cools down linearly over time.

After testing, whether it is put in water or sun, it will not affect the speed of cooling, as if this piece of metal will always dissipate heat to the outside with the same efficiency.

This property makes it a stable heat source even though it is not very efficient.

As long as the time is calculated, there will be no accidents and, to some extent, more reliable than electricity and fuel.

"It's fine."

Dong Junwei nodded: "I haven't been out since I came into this room, and I just went out for a walk this time." ”

Tang Jing said: "Don't worry, if you have a car to sit in this time, you won't be tired, and with Chen Dui with you, safety is not a problem." ”

"The squad leader is a humanoid tanker, so he will still be tired." Chen Du smiled.

It takes half of the mental energy to keep the vehicle running for 20 hours a day, which is not an easy task.

Chen Du said again: "In addition, since I drove this time, I plan to simply go out for a few more days, if possible, it is best to find the other 8 gathering points marked by the blue monument, An Ruosu only knows one of them, and I am not sure if there are people now, but I think at least go and see first." ”
