What makes wood easily burn?

[incorrect0000]

Wood burns easily because it is a combustible material that contains three elements needed for combustion: fuel, oxygen, and heat. When all three are present in the right proportion, a chemical reaction known as combustion occurs, which releases energy in the form of heat and light.

The fuel in wood is primarily made up of cellulose, hemicellulose, and lignin, which are all organic compounds composed of carbon, hydrogen, and oxygen. When heated to a certain temperature, these compounds break down and release flammable gases, such as methane and carbon monoxide, which can then react with oxygen in the air to produce a flame.

Oxygen is also essential for combustion to occur. The air contains around 21% oxygen, which is usually enough to sustain a fire. As the wood burns, it reacts with oxygen to produce more heat and light, and this process continues until the fuel is consumed or the oxygen supply is cut off.

Finally, heat is required to initiate and sustain the chemical reaction of combustion. In the case of wood, heat can be provided by a match, a lighter, or any other source of heat. Once the heat is applied, the fuel in the wood begins to break down, releasing flammable gases that react with oxygen to produce a flame.

In summary, wood burns easily because it contains fuel (organic compounds), oxygen, and heat, all of which are needed for the chemical reaction of combustion to occur.
