How is charcoal produced from wood?

• A. Charcoal is produced by burning wood in high oxygen conditions.
• B. Charcoal is produced by burning wood in low oxygen conditions.
• C. Wood cannot be converted to charcoal.
• D. Charcoal formation requires high moisture.

Answer: (B)

Charcoal is produced by heating wood in low-oxygen conditions. This process, called pyrolysis, drives off water and volatile compounds while the solid remains carbon-rich. With plenty of oxygen, the wood would burn completely to ash and CO2 instead of forming charcoal. Moisture complicates things because energy is spent evaporating water, lowering the efficiency of carbonization and often increasing smoke. So, the best explanation is heating wood with restricted oxygen to carbonize it into charcoal.
