If you pulled the pin and threw a grenade in outer space, would it explode?

Question

On the same note, what about a gun? Would the bullet fire? Why or why not?

Answer 1

Actually, the grenade will not explode, but the gun will fire that bullet.

The grenade uses a burning fuse. The length of the fuse determines how long the grenade takes to explode. But you could custom make a grenade with an electrical-circuit fuse or a spring-****** primer. That would explode because the explosive (gun powder or high-explosive) contain the necessary oxygen.

A (hand)gun cartridge uses smoke-less powder. This modern version of gun powder also contains the oxygen it needs. The cartridge uses a primer to fire the bullet. A gun uses a mechanical strike from a "firing pin" to trigger the primer. The primer converts the mechanical motion into a chemical action to fire the powder. Then the burning gas expands in the gun barrel and pushes the bullet out of the barrel.


By the way:
The explosive dispersion of materials is the same in space or in atmosphere. The damage comes from a pressure wave many thousands of atmosphere in magnitude. The explosion will send out it's own matter. And space isn't a perfect vacuum.

Answer 2

Yes the grenade would explode. Gravity has nothing to do with an explosion. A bullet would also get fired because of the same reason. Although the bullet would never stop unless it hit something or got pulled into a gravitational pull of a planet/moon and then eventually hit that.

Answer 3

It would.
Explosives have materials that contain oxygen them selves so no air is needed.
They also have other substances that cause fast chemical reactions, which makes materia expand rapidly -> explosion.
Granades bullets etc. work all.

Answer 4

yes.....
only the bullet will never stop

Answer 5

yes

Answer 6

In space where it is vacuum, there is no air or gas to facilitate explosion (which is sudden expansion of gas). The burn may quickly extinguish inside.
