Question

within a firearm, a burning material creates pressure to force the bullet or shot out of the barrel. what is this burning material? a primer b firing pin c wad d powder

Explanation:

• Primer: It is a small amount of chemical compound that ignites the gunpowder, not the burning material that creates pressure.
• Firing pin: It is a mechanical part that strikes the primer to initiate the firing process, not a burning material.
• Wad: It is a component that separates the powder from the shot or bullet and can help with the distribution of shot, but it is not the burning material that creates pressure.
• Powder (gunpowder): When ignited, gunpowder undergoes a rapid chemical reaction (burning) that produces a large amount of gas. This gas builds up pressure in the firearm's chamber and barrel, forcing the bullet or shot out.

Answer:

D. powder
