I Will Not Live as a Genius - I Will Not Live as a Genius chapter 30

30. Hanon Thirteen

Science Contest.

It was a fairly large event, with 10 students per grade, a total of 30 students and science teachers attending.

The school rented a tour bus, and on Saturday morning, we got on the bus and departed from school.

“By the way, did you prepare a lot for the contest?”

Youngmi smiled at my question.

“No, I just want to participate. I went last semester too, and this is more fun than I thought.”

“Wouldn’t it be nice if we were still in the rankings?”

Youngmi smiled softly and said.

“Well… I don’t really care, do I?”

Yes, I think we should come and make good memories with Youngmi without any sexual burden today.

The blue autumn sky outside the window is very pretty.

The bus that took us arrived at the university located in Daejeon, and we followed the teacher’s guide to different buildings for each grade level.

The competition was divided into morning and afternoon schedules. In the morning, a lecture by a university professor was held for an hour, and it is said that the full-scale competition will be held in the laboratory in the afternoon.

large classroom.

The chemistry professor’s lecture began.

The lecture title is… It was ＜Intrinsic property of material: specific heat>.

Specific heat or heat capacity.

It means the heat energy that a substance can hold, and it is precisely defined as the thermal energy required to raise the temperature of a substance with a mass of 1g by 1 degree.

For example, since 4.2 J of energy is required to raise 1 g of water by 1 degree, the specific heat of water is 4.2 J/g/C.

The professor’s lecture, which started with the definition of specific heat, led to an explanation of the specific heat values of various substances.

Since water belongs to a substance with a fairly large specific heat, it is said that ammonia and hydrogen gas are the substances with a higher specific heat than water.

Conversely, metals such as iron and copper have relatively low specific heat, and each metal has a different specific heat value.

In particular, expensive precious metals such as gold and silver have very small specific heat values compared to iron and titanium, so they do not feel cold to the touch.

It was the last lecture.

The professor emphasized the properties of water.

The simple fact is that water boils at 100 degrees and freezes at 0 degrees.

The professor continued.

“Unless it turns into steam or ice, the temperature of water cannot exceed 0 to 100 degrees. What this means is that if you boil water for ramen, the water temperature will stay at just 100 degrees while the water is boiling. okay?”

The students answered the professor’s question with one voice.

“yes!”

“Conversely, consider the situation where you put a block of ice in water. No matter how much ice you put in the water, as long as the water doesn’t turn into ice, the water’s temperature will stay at just 0 degrees. Do you understand?”

“yes!”

“Be sure to memorize these two characteristics of water in your mind. Let’s have a delicious lunch then, and see you in the laboratory in the afternoon!”

The lecture ended with applause from the children, and we ate the lunch box prepared at school.

After lunch break, the real science contest began.

Our grade 10 students participated in the competition divided into teams A and B from Southwest Middle School.

Team A consisted of Sangtaek, Jihoon, and Jaeyoung, including me and Yeongmi, and Team B consisted of Lim Yeonji and four other students.

A total of 15 teams from 8 schools participated in the competition, and the large laboratory was filled with the sounds of about 80 children chatting.

1 o’clock on the hour.

When the professor entered the laboratory, the noisy laboratory became quiet in an instant.

The professor started writing on the large blackboard in front of the laboratory.

‘You are given the three pieces of metal below.

– steel

– Copper

– aluminum

Find the specific heat of each of these metals.’

After finishing the writing, the professor opened his mouth.

“Now, you need to find the specific heat of the metal. Now on the table are these three pieces of metal, a Styrofoam cup, a thermometer, a beaker, a burner and a bucket of ice. Have you all checked?”

We answered all at once.

“yes!”

“Among them, Styrofoam cups, thermometers, and beakers can all be used, but neither the burner nor ice can be used. In other words, you have to choose between the two.”

“… … .”

“I’m going to give you just ten minutes… Discuss with your crew for 10 minutes to decide whether to use a burner or ice first. The experiment proceeds after that. Now, let’s start the discussion!”

There is one thing on the bus going to Daejeon today.

During the competition it was decided that I would never take the lead.

If I, who has memories of my past life, plays a leading role… .

Because this is not fair play.

But this was really a pointless worry.

Should I choose between a burner or ice… .

I don’t feel it at all

Not only this.

To be honest, I couldn’t picture the specific experimental procedure for finding specific heat in my head.

no… I… Even though my major was math… My name was a university professor… .

this… I feel like a scratch is being drawn on my self-esteem.

The captain, Youngmi, opened her mouth.

“I think a basic experiment starts with water and a thermometer in a styrofoam cup. Is not it?”

The children nodded and Yeongmi continued.

“After that… If you put water in a beaker and boil the water with a burner, the temperature will be maintained at just 100 degrees, as the professor said in the lecture.”

Jihoon nodded and said.

“ah… ! I guess So, if you put a piece of metal in boiling water, it will be 100 degrees, and if you put a piece of metal that has been heated to 100 degrees back into the Styrofoam cup, the water temperature will rise as much as the specific heat of the metal.”

ah… ! It was only after hearing Jihoon’s explanation that I began to understand.

At this time, if the temperature rises a lot, the specific heat of the metal is large. That is, the specific heat is small.

Jihoon is this guy! You are smarter than I thought!

Jaeyoung said.

“Then, ice water is always at 0 degrees… If you put a piece of metal in ice water and then put it in a Styrofoam cup, the temperature of the water in the cup will drop. So, the principle is ultimately the same. Is not it?”

The children nodded, and Sangtaek said.

“Ice water is available right away, but the burner has to wait a long time for the water to boil.”

This time, I received Sangtaek’s words.

“Then I think the decision will be simple, right?”

said Sang-taek.

“Then shall we choose ice?”

All the children nodded their heads.

At that moment, the professor’s loud voice was heard in front of the laboratory.

“ruler! One minute left. A decision must be made soon.”

Sang-taek said again.

“Is everyone okay with ice?”

Everyone seemed to agree with Sangtaek’s words.

“Wait a minute… !”

it was young

“By the way, if the duration of the experiment is 1 hour and 30 minutes, there is enough time to boil water.”

The children nodded again, and there was silence.

The professor standing in front of the laboratory checked the clock, and at that moment, Youngmi and I met their eyes.

I squinted my eyes slightly towards Yeong-mi, then turned to look at the clock in front of the laboratory.

It was a signal to Young-mi, the captain, that time was running out.

Young-mi, who checked the watch, said to the children in an urgent voice.

“Guys! We must choose our burner!”

Suddenly, the teacher’s voice was heard.

“Now, captains, come forward and tell us what you have chosen!”

Jaeyoung said to the children.

“I don’t know why… If Yeong-mi thinks she should pick a burner, I’m in Chansung.”

All the children, including myself, nodded, and Yeong-mi went to the front of the laboratory on behalf of our group.

According to the professor’s instructions, the forward leaders were divided into two groups… .

Three groups, including Yeong-mi, chose the burner, and Lim Yeon-ji and the 12 team members selected the ice.

said the professor.

“ruler! Then, the 12 captains who chose ice, go back to their seats.”

The voices of our group’s children were heard.

“Five… ! I think the burner was right.”

“Oh yeah! I think I was good at trusting Youngmi.”

The professor asked the three remaining children.

“Why did you choose a burner?”

The first student, standing right next to the professor, opened his mouth with a hesitant expression.

“just… yo. this.”

The professor smiled and asked the second student, and the large male student who was asked the question said with a confident expression.

“We decided on rock-paper-scissors.”

“Wah-ha-ha—!”

As the laughter subsided, the professor asked Young-mi the same question, and Young-mi pointed her finger at the clock and said:

“There… The laboratory temperature is written on it.”

uh… ? Wasn’t it a watch?

Come to think of it… In the corner of the blackboard next to the clock, it was written that the laboratory temperature was 20 degrees.

The professor nodded, and Youngmi continued.

“So you are saying that the temperature of the water in the Styrofoam cup is 20 degrees. So if you choose ice, the temperature difference with ice water is only 20 degrees.”

A small smile began to spread across the professor’s face,

Youngmi continued the explanation.

“But if you boil water with a burner, the temperature difference from boiling water is 80 degrees, so if you transfer a piece of metal heated at 100 degrees to a Styrofoam cup, the temperature change will be bigger, and then you can measure the specific heat more accurately.”

While the professor nodded with a satisfied expression, Jaeyoung put her hands on her mouth and shouted.

“He’s our captain!”

The lab burst into laughter, and as the laughter subsided, the professor said.

“Very accurate. The explanation is so good that I don’t have much more to say. Everyone applaud!”

The experiment started.

We light the burner and wait for the water to boil.

Youngmi, who was sitting next to me, spoke to me in a low voice.

“Thank you for that.”

“yes? what?”

Yeong-mi moved her gaze to the blackboard on which the temperature was written, then looked at me again and smiled.

ah… !

Youngmi thinks I gave a hint… !

It seems strange to deny that my original intention was not.

I just can’t help but laugh… .

The experiment went smoothly.

We put the copper pieces in boiling water and waited for about 1 minute, and after 1 minute we took out the copper pieces and put them in a Styrofoam cup.

The thermometer, which was showing 20 degrees, moved slowly and exceeded 27 degrees.

We experimented with iron and aluminum pieces in the same way, and Jaeyoung was in charge of recording the experimental results.

While doing this experiment… .

The university student assistant hyung took a large camera and captured the images of the students doing the experiment.

When the experiment on the last piece of aluminum was finished, Youngmi said.

“Then the experiment is over, now the burner is off.”

The children nodded, and Yeong-mi put the lid on the alcohol burner and turned off the fire.

That was then.

Rouge, who was at the table on the other side of the lab, said as she ran towards our table.

“Guys—-!”

uh… ? However, Rouge was even wearing a coat, and the sleeve of the right arm of the coat was lowered and covered the tips of the fingers.

Running, she lost her balance for a moment and fell on the experiment table, and her right hand, covered with a sleeve, strongly pushed the beaker on the tripod.

And the beaker filled with boiling water flew towards Yeongmi.

“Ugh!”

Clang—!
