Question

why charcoal burns so hot even though it’s already been burned

In: Physics

Answer 1

So when you make charcoal your actually burning the impurities out of it. Whats left is pure carbon,much like coal, which oxidizes at a much higher temp than impure carbon. The impurities take up oxygen that could otherwise fuel the carbon combustion.
