Burning

Burning is a complex physical and chemical process of converting raw materials into products of burning. Burning reactions are accompanied by intense heat release. The chemical energy stored in the components of the original mixture, can be isolated in the form of light and heat radiation.

But, if you ask a chemist, why the burning of wood or coal is observed only at high temperature, it will say that the compound of carbon and oxygen takes place at any temperature. However, at low temperatures, the burning takes place very slowly. It therefore escapes our observation. The law defines the rate of chemical reaction says that with decreasing temperature at 10 degrees the reaction rate is reduced by half.

Let's look at the burning firewood. At a temperature of 600 degrees Celsius burns 1 gram every second timber. Let's count, how long it will burn 1 gram timber at 20 degrees Celsius? We already know that at a temperature which is 580 = 58x10 degrees Celsius below, the reaction rate is less than 258 time. This means that the burning of 1 gram of wood will last 258 seconds...

How many years is a period of time? After a simple translation, we learn that the burning of wood grams without flame and heat would have lasted 10 billion years!!!

Thus, wood and coal burning and at ambient temperature. Flames of fire sped up this very slow process billions of times.
