powder
Usually a slow-burning material like cotton or hemp soaked in a solution of saltpeter or potassium nitrate is placed on a linstock to make it burn slowly. This helps control the ignition of the gunpowder in a firearm.

KNO3 (potassium nitrate) is used in gun powder as an oxidizing agent. When gun powder is ignited in a confined space, it rapidly decomposes to release gases that build pressure, propelling a projectile like a bullet out of a firearm. Potassium nitrate supplies oxygen for this reaction to occur.

Factors that affect the presence of gunpowder residues include the type of firearm, the type of ammunition used, the distance from the target, environmental conditions such as temperature and humidity, and the surface on which the residue is deposited. Additionally, the cleaning and maintenance of the firearm can also impact the presence of gunpowder residues.
Generally, yes. A cannon is a weapon that shoots a projectile out of a tube by exploding or burning combustible material (gunpowder). But under federal United States laws on the sale and transportation of "firearms" an antique blackpowder cannon, or a faithful replica of one, is not a "firearm."
An arquebuse is a trigger-based handgun or firearm by which a burning match can be applied.
The primer in a bullet contains a small amount of explosive material that is ignited when struck by the firing pin. This explosion creates a flame that ignites the gunpowder in the cartridge, causing it to burn rapidly and create gas pressure that propels the bullet out of the firearm.
Generally speaking, it is a device designed to expel a projectile driven by the force of burning gunpowder.
In the United States, a working bazooka / RPG/ Panzerfaust/ anti-armor weapon / Light Armor Weapon is a special type of firearm called a "destructive device." There are special laws that apply to those kinds of firearms that do no apply to ordinary firearms. By design, a bazooka is a type of firearm because it throws a projectile forward by means of exploding or rapidly burning material. But unlike a regular firearm, the bazooka is not a closed container where the only way for the high-pressure gasses to escape is to push the bullet or shell down the barrel. A bazooka is more like a rocket that is launched from a thin hollow tube. The tube helps aim the rocket and protects the user from getting burned by the rocket's exhaust.
When it fires with very little pressure on the trigger.
The definition of the term is, "a small arms weapon, as a rifle or pistol, from which a projectile is fired by gunpowder."
Yes, higher grain bullets tend to produce higher psi (pressure) because they contain more gunpowder, resulting in a more powerful and faster bullet velocity when fired from a firearm. The increased energy from a higher grain bullet creates more pressure within the cartridge, leading to higher psi levels upon firing.
That portion of the firearm through which the projectile is propelled by the burning of the powder charge. Unless a smoothbore, it also imparts spin on the projectile to stabilize it.
A trigger made of more than one material. Carbon, wood, fiber, steel etc..
By technical definition, a paintball marker is not a firearm, but more so in the airgun category (as it's usually powered by compressed air rather than the expanding gases from the combustion of flammable materials, i.e. gunpowder or propane [exceptions do exist for the latter material as few manufacturers did make a paintball marker that run on expanding gases from burning propane]). Legally (under the law) in some areas and jurisdictions a airgun can still be considered a firearm.
