Question

i am doing a report on gunpowder tell me what you know thanx

Answer 1

Gunpowder, whether black powder or smokeless powder, is a substance that burns very rapidly, releasing gases that act as a propellant in firearms. Both forms of gunpowder are low explosives.

As a result, pressures generated inside a gun are sufficient to propel a bullet, but not sufficient to destroy the barrel.

Gunpowder was the first known chemical explosive and propellant. The earliest record of gunpowder was in China about 850.

Black powder is a mixture of saltpeter (potassium nitrate or, less frequently, sodium nitrate), charcoal and sulfur with a ratio (by weight) of approximately 15:3:2 respectively. The ratio has altered over the centuries of its use, and can be altered somewhat depending on the purpose of the powder.
