      Fire is the chemical reaction between a fuel (e.g. Wood) and oxygen in the air. The energy trapped in the fuel is transformed into heat.

      Different things actually burn at different temperatures, which is why you get different colours in flames. Red flames mean that the fire burns between 500°C and 1000°C, orange means the fire is between 1000°C and 1200°C and flames go white above that.
