What are gases in explosion?

Gases in an explosion typically include a mixture of combustion products, such as carbon dioxide, water vapor, and various nitrogen oxides, depending on the materials involved. When a combustible substance ignites, it rapidly converts into gas, expanding rapidly and creating high pressure. This rapid expansion leads to shock waves and can result in destructive force. The specific gases produced can vary widely based on the nature of the explosive materials and the environment in which the explosion occurs.
