Understanding Combustion: Wood vs. Charcoal

The video explores the chemistry of fires, comparing wood and charcoal as fuel sources. It explains combustion as an exothermic reaction, highlighting the differences in heat and smoke production between wood and charcoal. The process of pyrolysis is discussed, along with the challenges of using damp wood. The video also addresses the environmental impact of charcoal production, particularly deforestation. It concludes with a reminder to choose the appropriate fuel for summer activities and acknowledges contributors.
