1. What is the underlying process?Pyrolysis: thermal decomposition of wood in limited oxygen
2. What is the primary function?Conversion of wood into a higher-energy density fuel (charcoal)
3. How does a charcoal pile make charcoal?The wood is stacked in a cone or dome shape, a fire is started in the middle, and soil or clay covers it to keep out air. The heat slowly turns the wood into charcoal.
4. Why do people use charcoal instead of regular wood?Charcoal has more energy and burns hotter and cleaner, so it is better for cooking, heating, and making metal and glass.
