Chapter 212 Gold
management is a huge topic that is invisible and intangible, but neither companies nor countries can ignore its existence. If Qiming wants to continue to exist, it has to pay attention to this aspect.
Chen Mu used to only focus on living his own life and had no experience in these things. After listening to Dong Junwei's clear and logical explanation, he naturally would not object.
During the days when I go out, because there are fewer manpower, there will definitely be a interruption in construction. In this case, doing some construction of spiritual civilization and rules and regulations is also a way.
After two days.
The heat storage time of the three metals is finally completed.
The final data are:
aluminum: 7 hours;
stainless steel: 26 hours;
copper: 46 hours.
Obviously, using copper as a heat source is more effective than stainless steel.
There were a lot of wires found in the second carton, and copper had no advantages as a building material, so it was perfect for this purpose.
"What patterns can be seen from this kind of data?"
Chen Mu only knew the density of the specific values of those attributes. It was obviously impossible for him to summarize any patterns.
"I can think of one." Tang Jing said.
"What?"
"According to the current ratio, the most suitable attribute should be liveliness."
"Metal liveliness?" Chen Mu was stunned.
"Yes." Tang Jing nodded.
"But why is the activity related to the heat storage capacity of the material?" Chen Mu asked again.
"It's hard to say. The activity of metal refers to the tendency to lose electrons to form metal cations in aqueous solution. This is a thermodynamic concept." Tang Jing said: "If I have to say it, it is this connection. Of course , even if there is no connection, things like superpowers are inherently unreasonable, and all we can do is summarize." "I remember that the
specific manifestation of liveliness should be..." Chen Mu was confused for a moment Stuck on that word and can't say it.
"Standard electrode potential." Tang Jing answered.
"Aluminum is the most reactive?"
"Of these three, yes, but among all metals, lithium should be the most reactive, which is the kind of metal used in batteries. I did a rough calculation and found that lithium's heat storage time is only 4.5 months hours, and what we need is the least lively one."
"Which one is the least lively?" He Ying asked.
"Gold." Tang Jing said.
"Gold?"
"Yes." Tang Jing said: "I calculated the heat storage time of gold to be 124 hours. If I guess correctly, its upper temperature limit will be higher. If used on an engine, it can probably supply 80 Many hours, based on the squad leader's current ability."
"But gold is hard to find..."
"Yeah."
"What about something worse?"
"Silver, more than 60 hours."
" It's not easy to find either."
Dong Junwei suddenly said: "I know where there is gold."
"I also know, bank vault?" Chen Mu said with a smile.
"I mean inside the school." Dong Junwei said.
"There are them in school too?"
"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 immediately.
"Well, every time she came to school, she would bring her jewelry with her on the way, but when it was time to go to class, she would lock the jewelry in her desk." Dong Junwei recalled.
"Squad leader, how did you know?" Chen Mu asked curiously.
"She told me." Dong Junwei spread her hands.
"Why did Teacher Qi tell you this?" He Ying asked in confusion.
"Last time I went to her office to help out, I complimented her bracelet on how beautiful it was, and we talked about it by the way." Dong Junwei remembered what happened in school before, and smiled unconsciously and said, "As you know, students are not allowed to wear It's jewelry, but in fact, teachers don't encourage wearing it in principle, but Teacher Qi is born with a love for beauty, so she used this compromise." "
But aren't you worried that it's unsafe to put jewelry in your desk?" Chen Mu asked confused.
"The school is the safest. There are cameras everywhere in the corridors of the office. There are so many people coming and going. Who would steal things here?" Dong Junwei said: "Besides, it's just some ordinary gold jewelry. My husband is very rich. These things It's probably similar to a toy."
Chen Mu couldn't help but laugh when he didn't expect that the class monitor, who usually looked aloof, would also be beaming when talking about these teachers' gossip and trivial matters.
"When the disaster struck, it was during the second period of class. I guess there was a high probability that the gold jewelry was still in the desk." Dong Junwei said.
"Then let's go look for it next time we go out?" Chen Mu said.
"You can consider it."
Tang Jing said, "Where is Teacher Qi Luo's office?"
"The offices of the associate subject teachers are in the administrative annex building. Teacher Qi is in Room 309 on the third floor." Dong Junwei said.
"In this case, our next goal is to drive up there and bring back a container of gold." Chen Mu said.
"I suggest that the squad leader go together." Tang Jing said suddenly.
"Me?" Dong Junwei was stunned.
"Well." Tang Jing said: "Even if copper is used as the heat source, the vehicle can be used for no more than 20 hours at most. If the heat cannot be replenished midway, the engine will stop. Therefore, letting the squad leader go with you can improve efficiency. Wait a moment Now that you have gold, you don’t need it.”
Although copper has a heat storage time of 46 hours, because the temperature of the metal heat source will gradually decrease over time, the time it can actually be utilized by the engine is only 20 hours.
The metal that Dong Junwei heated has a characteristic of cooling down.
That means it has nothing to do with the surrounding environment.
It only cools down linearly over time.
After testing, whether you put it in water or put it in the sun, it will not affect the cooling speed. It is like this piece of metal will always dissipate heat with the same efficiency.
This characteristic makes it a stable heat source although it is not very efficient.
As long as you calculate the time well, there will be no surprises. To a certain extent, it is more reliable than electricity and fuel.
"That's fine."
Dong Junwei nodded: "I haven't gone out since I came into this room. It just so happens that I go out for a walk this time."
Tang Jing said: "Don't worry, there will be a car this time, so you won't be tired, and Chen Mu will take you there." If you stay, safety is not a problem."
"The squad leader is a humanoid tanker, so he will still get tired." Chen Mu said with a smile.
It takes half of the mental energy every day to keep the vehicle running for 20 hours. This job is indeed not easy.
Chen Mu added: "In addition, since I drove this time, I plan to go out for a few more days. If possible, it is best to look for the other 8 gathering points marked by the green monument. An Ruosu only knows one of them. I'm not sure if there's anyone there right now, but I think I'll at least go take a look first."
