Simultaneous development of heat and light, which is the product of combustion of flammable materials. It is the chemical reaction between fuel and oxygen in the air (oxidizing) in the face of a heat source. In order to have fire there must be three essential elements of combustion, which constitute the so-called "Combustion Triangle". Are they:
- Fuel
- heat
- Oxidising Oxygen
Fire is a chemical process that strictly obeys the Laws of Defined Proportions or Proust's Laws, that is, the disordered configuration of these three elements will not produce fire. If we suppress this triangle, one side of it, we will eliminate the fire
