2020年5月3日 · 1 pound of black powder contains .733 mega joules of energy, but amount of force released is a question of context. The force will be much higher if the energy is rapidly released in a small area (like inside a cannon). For the largest barrel that means a potential for 65.97 MJ of energy released.

A powder keg is a barrel of gunpowder. The powder keg was the primary method for storing and transporting large quantities of black powder until the 1870s and the adoption of the modern cased cartridge.

Gunpowder is classified as a low explosive because of its relatively slow decomposition rate, low ignition temperature and consequently low brisance (breaking/shattering). Low explosives deflagrate (i.e., burn at subsonic speeds), whereas high explosives detonate, producing a supersonic shockwave.
