Will a gun fire in the vaccum of space?

Modern firearms propellant has O2 locked up in it already.

The oxygen is locked in to the chemical composition of the propellant.

The reason the O2 is chemically in the propellant is the combustion of the propellant needs to be too fast to get O2 from around the cartridge. Also a cartridge would not contain enough air space inside to provide the O2 required for such an energetic explosion.

So yes it will fire in a vacuum. With 14psi more force because that is taking away atmosphereic pressure.

I am curious......Does the cartridge need O2 to fire......Don't guns fire underwater??

Your thoughts on this subject.

most guns will fire underwater, in the vacuum of space most will too, but its reliant on the necessary gasses being present in the cartridge. A gas powered gun will also fire both underwater and in the vacuum of space. However, more resistance will happen underwater leading to a very inneficient firing of both types of weapon.

Actually it depends on the physics and pressure of the situation. If you are on the top of the ocean's surface using a regular manufactured cartrage the gun should fire about as well as it would on the surface Some accuracy might be loss, but not a substantial enough an amount for you to notice with the naked eye.

Now lets ponder if you could get down into the very depths of the ocean where the pressure is powerful enough to crush you or any substantial life form. Depending on how well your cartrage works, in theory I'm speaking, the pressure might be so powerful that as soon as you shoot the gun it would cause an immediate backward pressure motion that could wipe out all life forms

Remember no lifeforms could really exist in the type of pressure I'm talking here. It's in theory. In short terms it is possibly that a single bullet shot from that of a pistol could be transferred into the same pressure of a light mass bomb. Meaning that if you shot just a single bullet from a pistol you had it could feel like you were hit by a light mass bomb.

yea, it can fire in space. and yes they can fire under water but they are not powerful and it will only kill something that's 2 feet away. o and regular guns have a problem reloading under water but they have special guns that work perfectly fine under water.

Yes, it will fire....the explosion in the firing of a gun is internal in the cartridge, and providing their is enough "air" in the cartridge itself, it should be sufficient to fire.....

Yes, under the same principle it will fire underwater, however, underwater it will lose any accuracy and most of its energy rather quickly.....

The gun will fire as no gas force is present which will resist the speed of bullet

No one can provide an answer any better than the one posted by (the unborn),he's right. I hope Yahoo answers put on a tab, firearms and shooting.

im no scientist...

underwater or in a vacum theres enough "02" in the case to burn the powder. it wont go far in water becauseof the pressure.pneumatics and fluid mechanics says u cant really compress liquid much if at all. for gasoline fuel to burn the air fuel ratio most desireable is 14.7/1 lots of air. i would assume that its similar in dry powder and that since its a sealed system untill long(relatively) after its fired that they set it up correctly stand alone.

If the seal on the shell and bullet is tight enough it will unless it leaks out. When you fire a gun here it doesn't suck air in then fire, it is in it all ready
