What does a firearm launch?
Correct Answer
A. Projectiles
Explanation
A firearm launches projectiles. Projectiles refer to any object that is shot or propelled through the air, such as bullets, pellets, or other ammunition. Firearms use the force created by the explosion of gunpowder to propel these projectiles forward, enabling them to hit a target with force and accuracy.
2.
What exothermic combustion produces the high pressured gas?
Correct Answer
A. Deflagration
Explanation
Deflagration is the correct answer because it refers to a type of combustion that produces a high-pressure gas. It is a rapid chemical reaction that releases energy in the form of heat and light, causing a sudden increase in pressure. This process is commonly observed in explosions and can occur in various substances, such as fuels or explosives.
3.
What century did the first primitive gun originate?

7.
What did Older firearms typically use as a propellant?
Correct Answer
A. Black Powder
Explanation
Older firearms typically used black powder as a propellant. Black powder, also known as gunpowder, is a mixture of sulfur, charcoal, and potassium nitrate. It was the first explosive propellant used in firearms and was widely used until the late 19th century when smokeless powder was introduced. Black powder produces a large amount of smoke when ignited, hence its name, and it was commonly used in muskets, cannons, and early firearms.
8.
What is used in modern firearms as propellant?
Correct Answer
B. Smokeless Powder
Explanation
Smokeless powder is used as a propellant in modern firearms. Unlike black powder, which was commonly used in older firearms, smokeless powder produces less smoke when ignited. It is made up of nitrocellulose, which burns at a controlled rate to generate the necessary pressure to propel the bullet. Smokeless powder is more stable and efficient compared to black powder, making it the preferred choice in modern firearms.
9.
What is the calibre of a modern firearm measured in?
Correct Answer
A. Inches
Explanation
The calibre of a modern firearm is measured in inches. Calibre refers to the internal diameter of the barrel of a firearm, specifically the diameter of the projectile that it fires. The measurement is typically given in inches, indicating the size of the bullet that the firearm is designed to shoot. This measurement is important for determining the compatibility of ammunition with a particular firearm and for ensuring accuracy and effectiveness of the weapon.
10.
What describes the calibre of a shotgun? Its __
Correct Answer
A. Guage
Explanation
The calibre of a shotgun is described by its gauge. The gauge refers to the diameter of the shotgun's bore, with a lower gauge number indicating a larger bore size. This measurement is important as it determines the size of the ammunition that the shotgun can safely fire. Therefore, the gauge is a crucial factor in determining the power and effectiveness of a shotgun.
