What’s the process of burning wood?

When wood gets hot enough — such as when lightning hits or a log is tossed on an already burning fire — those bonds break. The process, called pyrolysis, releases atoms and energy. Unbound atoms form a hot gas, mingling with oxygen atoms in the air. … That releases more energy, which releases more atoms.

What energy does a burning fire produce?

Combustion changes the potential chemical energy into kinetic energy in the form of heat.

Is burning of wood endothermic or exothermic?

Burning wood provides heat through the exothermic chemical reaction of oxygen (O) with cellulose (C6H10O5), the major chemical component of wood, to produce carbon dioxide (CO2), steam (H2O) and heat.

Which wood burns longest?

Hardwoods such as maple, oak, ash, birch, and most fruit trees are the best burning woods that will give you a hotter and longer burn time. These woods have the least pitch and sap and are generally cleaner to handle.
