Combustibility refers to the ease with which a material can ignite and burn. It is a fundamental property of matter that determines how a substance will react in the presence of an ignition source and oxygen. Materials vary greatly in their combustibility. Some, like wood or paper, are highly combustible and ignite readily. Others, such as metals, may require much higher temperatures or specific conditions to burn. Non-combustible materials, like rocks or glass, will not burn under normal circumstances.

The process of combustion typically involves a chemical reaction between a fuel and an oxidant, usually oxygen, that produces heat and light. Several factors influence a material's combustibility, including its chemical composition, physical state, surface area, and moisture content. For instance, finely divided materials or those with a large surface area tend to combust more easily than their bulk counterparts. Moisture can also suppress combustion by absorbing heat.

Understanding combustibility is crucial in many fields, particularly in fire safety engineering, material science, and industrial process design. It helps in selecting appropriate materials for construction, designing fire prevention and suppression systems, and ensuring safe handling and storage of potentially flammable substances. Fire codes and regulations are largely based on the combustibility characteristics of various materials to mitigate fire risks.
