What Happens (Chemically) When Wood Burns?

The video explores the science of wood combustion, detailing the chemical reactions that occur when wood burns. It covers the structure of wood, the process of pyrolysis leading to smoke production, oxidation resulting in flames, and the formation of embers and ash. The video aims to provide a deeper understanding of these processes, enhancing the appreciation of campfires.

What is the primary focus of the introduction in the video?

• The molecular changes in wood during combustion

• The history of campfires

• Different types of wood

• How to build a campfire

Which components primarily make up the structure of wood?

• Volatile organic compounds

• Metal oxides

• Cellulose, hemicellulose, and lignin

• Carbon, hydrogen, and oxygen

What is pyrolysis in the context of wood combustion?

• The complete burning of wood

• The chemical decomposition of wood when heated

• The formation of metal oxides

• The cooling of embers

What happens during the oxidation process in wood combustion?

• Water is released

• Wood cools down

• Oxygen reacts with wood molecules to release heat

• Wood turns into metal oxides

What remains after the wood combustion process is complete?

• Carbon monoxide

• Methane

• Gray ashes

• Volatile organic compounds
