What is the hottest chemical made fire?

What is fire/a flame made of?

  • Everything else I can think of is 'made' of something. Eg water is H20, air is a mixture of gasses including oxygen, my desk is wood and so on, but what exactly is fire? Liquid/gas/solid? Chemical composition?

  • Answer:

    flame itself is in gas phase. At high temp., the valence electrons in gas get excited and jump from a lower energy state to a high energy state; then, when the gas begin to cool down, those electrons fall back to the original energy state and emit the energy it absorbed in the beginning. The energy is released in the different colors of light; that's the color of the flame you'll see. combustion is a chemical process, flame is more like a physical process. So, there isnt any accurate chemical formula for flame, just like there isnt any accurate chemical formula for combustion.

It's the results of a chemical reaction that are still hot enough to glow. Let's say you burn wood. You mostly get carbon dioxide and water. For a short time after the reaction, the carbon dioxide and water are hot enough to glow visible light

A flame is composed of gases hot enough to emit light. The gases are usually compustion reaction by-products: carbon dioxide, carbon monoxide, water, and can be very complicated with flame from a candle or a camp fire. These gases could be numerous types of carbon based molecules. But basically a flame is hot glowing gases.
