Fire! Fire! Fire! What this fire ???

There is nothing to be afraid to see the headline. There was no fire anywhere. There was a fire in our house because of the fire in the houses or any other establishment around us. But this fire has been discovered by our ancestors, so today we can live in this luxurious modern era, of course everyone will accept. But how much do we have to think about this fire? Let's say,

What is the fire:

Is it fluid, solid, or gaseous substance?
Stay, do not worry about you anymore, I try to get some scramble about it myself.

Ancient Greek alchemists thought the fire as a basic substance. They considered soil, air, water as basic elements. But from the modern definition of elementary matter, we know that none of these are basic, but they are composed of different elements, but they are composed of different elements.

In most cases, the fire is a mixture of heated gas. This is caused by chemical reactions, which occur mainly in the air between oxygen and various types of fuel. As a result of these reactions, carbon dioxide, steam, light, heat etc. are produced.

When the heat grows, the atoms of carbon or other elements present in the energy are illuminated by the atoms. This is called, light production process by heat - which is called incandescence or thermocyclone and in this process a light bulb is created. That is why the flames are visible due to the reaction of fuel.
If the flames are hot enough, the gas atoms are mirrored and they move to another state of matter. Which is known as Plasma.

The difference in color of flame depends on what is being burnt and how hot it is. The color variation is mainly due to the uneven temperature. Usually the most heated part of the fire, which radiates blue light. The coolest part is the top of the flame, which is reddish-orange or yellow-orange.

In our childhood, many of us often played with fire. I mean, trying to surprise many by showing the fingers on the flame. Actually, we used to shove fingers over this red-orange flame. But it would have felt a warm heat. But it would have been more heat if the fingers went wrong in the blue part of the flame.

The size of this flame in the fire controls the strength of gravity. The concentration of the heated gases between them is much less than the wind surrounded by them. But their temperature is much higher than the surrounding air. So the gases continue to move from low density areas to less concentration areas. This happens because of the force of gravity.
So the flame is usually spreading upward, because of that, its head is always needleful.
If we burn a fire in a space of zero gravity, such as space shuttle, then the flame will contain the shape of the spheres!

As seen in NASA's picture. As NASA creates an unmoderated environment, we see a round flame in the picture!

I hope you play with the fire, but you've got a little bit of this idea.
