      Burning is a chemical reaction that produces energy and gases and some of this energy is emitted as heat 🙂 some of it is emitted as light too 🙂

      Fire is the result of a chemical reaction which releases energy stored in chemical bonds. When something burns, the energy liberated is quickly released as heat and light, which we see as fire.

      In a common fire, the radiative energy is generally released as visible light and heat (infrared) — the color of the flame is usually an indication of the chemicals being burnt or released.
