Black powder is classified under which category of explosive attacks?

Black powder is classified as a propellant due to its use in various applications where it serves as a means to propel projectiles. Traditionally used in firearms and for fireworks, black powder generates gas and heat when ignited, which creates pressure and subsequently propels an object. This characteristic of generating high-pressure gas makes it an effective propellant.

In contrast, primary explosives typically refer to highly sensitive materials that can detonate with very little stimulus, such as lead azide or mercury fulminate. Mechanical explosives, on the other hand, usually involve physical mechanisms or processes that cause an explosion, rather than a chemical reaction like that of black powder. Demolitions involve the structured use of explosives for destruction, but black powder is not primarily utilized for that purpose in modern practices, which lean towards more powerful and stable materials. Thus, classifying black powder specifically as a propellant recognizes its primary function and characteristic in explosive contexts.
