At this time, all the moisture in the wood has evaporated, and its structure has also changed. The interior will have a honeycomb structure, which is easier to ignite, has higher combustion efficiency, and produces less smoke."

"Then the honeycomb structure is burned to produce a more violent combustion reaction and reach a higher temperature."

[I want to see a complicated explanation, funny]

"For a complicated explanation, if we take 'cellulose', the main chemical component of wood, as the object of investigation, the basic component of glucose is 'carbohydrates'."

"To compare glucose with charcoal, we use '1 mol of C6H12O6' to compare with the carbon element containing 6 mol of carbon atoms."

"Then, the 6 water in 'C6H12O6' will still be water after combustion and will not generate much heat. In other words, the combustion heat is mainly contributed by the 6 carbon atoms.

In this way, the combustion heat of wood and charcoal will not be much different. You can check the chemistry manual to see what the difference is in the combustion heat of the two."

[The heat of combustion of glucose is 2800kj/mol, while the heat of combustion of an equivalent amount of C is 2361kj/mol. Sorry, the difference is really not very big.]

Bi Fang smiled: "So, when wood is burned, it produces 6 carbon dioxide molecules, and at the same time, it also produces 6 more water molecules that also need to be heated."

"But! After burning charcoal, there are only CO2 molecules!"

"With charcoal, you don't have to worry about which water molecules are being heated. After charcoal is burned, the types of substances and the number of molecules that need to be heated are smaller."

"This is the most fundamental reason why the maximum burning temperature of charcoal is higher than that of wood!"

The rumen of cattle is the largest of the four stomachs, with a volume of 130 liters.
