Mizukawa took a cup and poured a drop of ink into it. He poured the mixture into the pot and began to heat it up, while the three of them waited patiently for the results. Suddenly, Mizukawa turned off the fire. Then, he said, "What do you think will happen in the end?"

Dueñas stared at the ink and said, "I've seen a video. It is said that a drop of ink is placed on the petiole of the leaf and then put it in clean water. Next, you can see that the leaves are constantly moving as if they have gained momentum.

The diffusion of the ink is violent, and it is even more intense when heated. It won't be long before the water in the pot will be contaminated with ink. The scene is that the ink spreads in all directions, and it explodes like a bomb. Even if the temperature is lowered, the water in the pot will not become clear again.

Margarita shook her head and said, "I don't think so. The ink spreads, but not as violently. Why? Because the heated water is doing a very intense and irregular movement, and the intensity of the movement is very high. Even if the ink tries to spread, it will be rejected repeatedly. However, the ink swells. The swollen ink slowly floats up until it floats on the water. When the temperature drops, it sinks again. Only a colander is needed to get it out.

Liuzifeng said: Unlike you, I don't think the ink will spread but will move. Why? The irregular molecular movement of the water is particularly violent, causing the ink to be repelled everywhere. Under the combined action, the ink begins to move. As for the trajectory of the movement, I guess it's hard to determine.

Mizukawa said with a smile: You have only seen one side, in fact, ink will go through all three conditions at the same time. However, there is one thing that is different, ink cannot completely pollute the water. If you don't believe me, I'll show you. As he spoke, he turned on the fire, and the water in the pot was being heated. After about two minutes, everyone saw what Mizukawa said, so they all fell silent. Seeing that everyone was silent, Mizukawa said again: If one more drop of oil is added, what will happen to the situation?

Margarita seemed to have known the answer for a long time, rushing to answer: due to the different densities, the oil and ink do not fuse. Even if the temperature is high, it will not change. However, they all spread.

Dueñas said slowly: the ink eventually rises to the surface and eventually melts with the oil. However, when the temperature is lowered, they separate.

Liuzifeng looked at the mixture: I don't think the ink will rise to the surface. Even if it does, it will be hindered by the repulsive force of the water and cannot be mixed with the oil.

Mizukawa smiled awkwardly: I haven't thought about this, so I won't say anything.

The three of them changed their faces in an instant: the question was raised by you, and you didn't know the answer. Aren't you kidding us? You must give us an explanation today, otherwise you don't want to leave.

Mizukawa didn't refute: I didn't plan to leave either. Besides, who says that the person who asks the question necessarily needs to know the answer? I want to tell you that there is still a lot to learn, and you can't just limit yourself to what you know. What is bias? It's just a little bit of knowledge, and you don't learn it. How to get rid of your prejudices? The only way is to learn! I remember that I used to have a lot of prejudices, but they gradually disappeared as I learned.

All three of them said, "It seems that you are quite good at making excuses and procrastinating for time." But if you're lucky, that's all for today.
