Hot and cold are the sensations that temperature gives people. There is heat in physics, and the most well-known sub-discipline of heat is thermodynamics. Today, we are going to talk about a very common thermal phenomenon called heat transfer. Heat transfer from a place with a high temperature to a place with a low temperature is called heat transfer. I've read the entry that says that if two objects have the same equilibrium state, then they have the same temperature. That is, the heat transfer is due to the difference in the equilibrium state of the two objects. However, I would like to ask you to think differently. How should heat transfer be explained in terms of others?

Let me start with my opinion. Temperature is the intensity of the molecular motion of the epiphany. Molecular motion will cause the internal shape of the object to change significantly, and vigorous molecular motion will cause the internal shape of the object to be in constant change. And the shape itself has energy, and it takes more energy to form a complex shape. The energy difference between two internal shapes is the temperature difference and is the essential cause of heat transfer. We've touched on the discussion of shapes more or less several times. It is certain that the shape has energy, while it is not clear whether it has mechanical properties or not. Mizukawa was the first to speak and made an opening remark.

Temperature refers to the amount of heat, and the temperature difference is the difference in heat. While temperature difference is the superficial cause of heat transfer, what is the underlying cause? Density. The motion of the molecules causes the position of the molecules of the object to be not fixed, so the volume of the object is in an unfixed state. Of course, there are certain variations in quality. It's just that the changes are small and negligible. In this way, the density of the object changes. According to the physical quantity, energy is required to maintain, so the energy corresponding to the density is also changing. The principle of lowest energy says that in order for a yin object to be stable, it must maintain a relatively low energy. If there is no object around that is lower than the energy of the object, then the object is in a steady state. Now that equilibrium has been reached, heat transfer will of course no longer take place. However, it is difficult for the equilibrium state of two objects to be the same. Furthermore, as long as there is an object that is not the same temperature as the object, then the heat transfer will continue. Therefore, there is a chain of heat transfer. It involves a lot of objects. We know that any object undergoes molecular motion, i.e. there are multiple heat transfers going on at the same time. Liuzi Fenglai also said a lot.

The molecules are in motion, and they never stop. We know that a particle has a mass at rest and a mass of motion. The mass at rest determines how fast an object can go, and the mass of motion will be clouded differently by the particles. I think calories are the quality of exercise. Why? Because both heat and moving mass are produced by the molecular motion of an object, it is difficult not to suspect that they are the same quantity.

The mass of motion is an unstable physical quantity. From a philosophical point of view, it is not real. That being the case, its instability is very high. It retains most of the energy in the moving mass by losing a portion of it. Margarita didn't say much, but hit the nail on the head.

Do you know the zeroth law of thermodynamics? I don't know? Do you want me to tell you? No, find out for yourselves!

You said so much without mentioning the most important concept of thermodynamics: entropy. In fact, entropy is the degree of chaos in a system. The result of all thermal motion is an increase in its entropy.

Well, that's probably it. Duenas said.
