We know that the essence of cold is low temperature, whereas heat transfer is simply from a place with a high temperature to a place with a low temperature. The heat transfer is irreversible, so we should not feel the cold. But we can. What's going on?

I'm not going to give you any hints, you can use your imagination. There is indeed something worth exploring about this issue of Mizukawa rice.

Because objects with low temperatures have to absorb heat. However, this begs the new question: why do cold objects absorb heat? Does this overturn the law of thermodynamics that heat transfer is irreversible? If not, what's the difference? In fact, we ignore that the cryogenic object is in the same system as us. The heat transfer is not three-dimensional, but planar. As a result, the surface of a cold object absorbs heat. However, in this way, there is a temperature difference between the cold objects. As a result, heat is transferred from the surface to the inside. Since the two heat transfers are continuous, we can feel the cold. It's short, but it's to the point. Liuzifeng seems to have thought about this problem.

Caused by temperature differences. We can't just look at it. First of all, people need to know that temperature differences exist. We know that heat transfer can easily occur, so it's easy to conclude that something is hot. From this, it is inferred that there is a temperature difference between objects. And this difference comes in two forms, one is hot and the other is cold. To put it bluntly, cold appears because of symmetry with heat. Dueñas also said very little.

Cold is a feeling. Where does it come from? Experience. Yes. If a person has not experienced cold, how can one know about cold. Descartes said I think, therefore I am. Since I say cold, then I must be cold represents the form in which a person's feelings about a cold object are embodied. But there's a question that's what I'm saying, must it have been my experience? Time travel is not possible now, yet it is widely used in movies and television dramas. What does this mean? Imagination is what really makes the cold. Although there are four seasons throughout the year, there are some places where there is actually only spring. So, do the people here know what it's like to be cold? I don't know. However, they can imagine. It is really possible that people in the past have never felt cold, but they have imagined it. Suddenly, one day, they felt cold. Actually, this is caused by their psychological effects. Inside, they are hell-bent on finding cold. So, they began to look for this feeling, consciously or unconsciously. When one day, when they find it, they won't look for it again. A cold word seems simple, but I don't know how many stories there are behind it. Margarita was so happy that she said it unconsciously.

As a continuation of the topic of heat transfer, cold is meant to supplement heat transfer. With cold, we can better understand heat transfer. I think there is merit in everyone's point of view. However, I prefer Margarita's philosophical explanations. Because cold does not appear suddenly, there must be a formation process behind it. Water says.

Both Liuzi Fenglai and Dueñas said: I knew that your relationship was not clear, so it is not surprising that you prefer her point of view.

Margarita stood up and said loudly: I have studied physics problems with you, and I have never been afraid of losses. And you two say I'm like that! Don't make jokes, and don't talk nonsense. If you have to say that, then we will drive you away.

The two immediately relented: We're just talking, don't take it seriously.

Margarita and Mizukawa went back to their rooms, and so did they.
