Fire is a common object in our lives. In the ancient Five Elements Doctrine of China, fire was regarded as one of the basic elements of the world, alongside water.

Fire has a great military application, and those famous battles were achieved through fire. In the battle of Guandu, Cao Cao's general said that the granary of Guandu led to the defeat of Yuan Benchu's army.

In the Battle of Yiling, Lu Xun burned the company camp and defeated Liu Bei. In addition, the princes of Zhou Youwang Fenghuo Opera pushed the fire to the peak.

In the Nine Songs of Tianxing, the sister chapter of the Yin Moon of the Qin Dynasty, Wei Zhuang mentioned the fable of taking chestnuts from the fire.

In history, Xiang Yu and Zhang Han fought in Zhuolu. And the rebel princes around the battlefield looked at Xiang Yu, as if the war had nothing to do with them.

This is the story of watching the fire from the other side. Although fire pervades human life, we know very little about it.

In physics, solid, liquid, and gaseous states are the three most basic physical states, and the ones we are most familiar with are, of course, solid and liquid.

In fact, there are a lot of things that aren't just solid or whatever. For example, flour and water can be turned into raw noodles, so is raw noodles solid or liquid?

Cement contains water in the beginning, so it is in a liquid state. But if you think about it, it's neither solid nor liquid.

When its water evaporates, it becomes solid. Even if you add water, you can't let it restore. So, what state is fire?

Actually, fire is a plasma object. That's pretty much all about fire. The next time is your time to play.

Mizukawa's opening is unpredictable and varied. Just now, Mizukawa said that fire is in a plasma state.

But how do I think fire is fluid? First, fire does not have a fixed shape. This is in terms of fractals, not in terms of the main form.

Its main shape is, of course, unchanged, as in the shape of a candle and a lighter's fire. The second is that it is liquid.

In fact, the first and second can be said to be mutually causal. If there is no liquidity, I am afraid that the fractal of fire will not change.

So, is fire a fluid? One thing can be said that yin is not, and fire cannot last. When the fuel runs out, it goes out.

Whereas, the presence of fluid is not attached to the object. I just mentioned that the main shape of the candle and the lighter is unchanging, so why is that?

I think it's because of the accumulation of fuel. It's very cloudy, the candles are neat, and so is the fuel in the lighter.

Good stacking, resulting in a neat flame. As soon as Liuzi Feng came to talk about it, he continued to explain the two phenomena very thoroughly.

。 We all know that there is a high point in the flames, but it is not here that the temperature is highest. The chemistry is called the flame heart.

That's not the point, though. What I'm trying to say is why the flame is going up, or maybe that statement is not accurate.

Because the flame has both upward and downward movements, and the flame flickers up and down for this reason. That said, the final movement of the flame is upward.

There are two problems here. First, answer the first one. Because the upward motion of the flame is stronger than the downward motion, the flame center of the flame should have been at its highest point.

As a result of the downward movement, a portion of the temperature is taken away, causing the flame center to shift downward. Secondly, up because of the altitude.

The higher the altitude, the lower the temperature. Due to the presence of heat transfer, the flame must go to the place above where the temperature is low.

Dueñas's explanation of the problem hits the nail on the head. This explanation can be regarded as a classic.

My question: Where does the red color of fire come from, do most combustibles contain red pigment? At that time, the theft of energy in the physics community bothered many physicists, and it was later discovered that it was caused by a new microscopic particle.

It is the neutrino, a well-known particle in physics. I think maybe fire is a special substance, and it probably produces a red particle.

And we know that natural gas is flame blue, which is determined by its chemical properties. For example, the combustion of some metals can produce a flame color reaction.

The second question is whether there is a force separating the positive and negative ions in the fire? I think there is.

It stands to reason that an object can only have positive or negative ions, and they will be neutralized when encountered.

If there are no particles separating them, then won't they disappear? Margarita said this, kind of an end.
