What Can Burn Underwater?

Do guns work in space?

Fires can’t burn in the oxygen-free vacuum of space, but guns can shoot.

Modern ammunition contains its own oxidizer, a chemical that will trigger the explosion of gunpowder, and thus the firing of a bullet, wherever you are in the universe.

No atmospheric oxygen required..

Do flares need oxygen to burn?

Your average road flare, and most of the pistol-launched ones, are not self-oxidizing; they need air to burn, so they can be smothered by a low-oxygen atmosphere (immersing in water, burying in sand, and in the vacuum of space).

Does water always beat fire?

Fandom. Water is supposed to beat Fire as they can extinguish them, not the other way. … Water beats Fire, Fire beats Air/Wind, Air/Wind beats Earth and Earth beats Fire, and so that is the cycle of the planet Earth’s nature of life.

Can flares start fires?

Flares ignite at 191 °C (376 °F) and burn as hot as 1,600 °C (2,900 °F). This makes them incredibly dangerous since they are well above the ignition temperature of most flammables found in a forest or wildland. … The flares are hot enough to start a fire instantly if they hit dry grasses or scrub.

Can a gun fire on the moon?

Gun: Yes. The oxidizer is within the gun powder, so a gun will fire in the vacuum of the Moon. The bullet will travel significantly farther, because it will fall slower and there will be no air resistance.

Can you use fire underwater?

Combustion needs oxygen to take place, if you provide an oxygen source by chemical or mechanical means, fire can burn underwater. A chemical reaction that gives up a lot of heat may stay burning for a little bit, but remember water has a high heat capacity and would cold the reaction quite fast.

Does napalm burn underwater?

Napalm is basically thick oil or jelly mixed with fuel (petrol, gasoline). … Versions of Napalm B containing white phosphorus will even burn underwater (if there is trapped oxygen in folds of cloth etc.) so jumping into rivers and lakes won’t help those unfortunate souls attacked with this vile weapon.

Does Greek fire burn underwater?

Both Greek fire and the Archimedes death ray were incendiary devices. According to the ancient accounts, Greek fire, developed in 672, was a substance that was easily ignited. Once lit, it burned extremely hot and could even stay burning under water.

Has a gun ever been fired in space?

Only after the fall of the USSR did Russian sources revealed that the cannon had actually fired in orbit. It happened on Jan. 24, 1975, onboard the Salyut-3 space station. … The outpost ignited its jet thrusters simultaneously with firing the cannon to counteract the weapon’s powerful recoil.

Can flares go underwater?

The flare will extinguish when placed horizontally in water (which is why puddles will extinguish flares) but vertical burning underwater shows that sufficient gas is being generated (as a byproduct of combustion) to displace the water away from the flame front.

Can there be fire in space?

In space, of course, you can’t have any fires because there isn’t any oxidizer (i.e. oxygen) to sustain the combustion process.

Are there bodies in space?

Space burial is the launching of samples of cremated remains into space. Missions may go into orbit around the Earth or to extraterrestrial bodies such as the Moon, or farther into space. Samples of cremated remains are not scattered in space so as not to contribute to space debris.

Is napalm illegal in war?

International law does not specifically prohibit the use of napalm or other incendiaries against military targets, but use against civilian populations was banned by the United Nations Convention on Certain Conventional Weapons (CCW) in 1980.

In the United States, it’s common to have a flare gun included in an emergency kit. You should be fine, what you use it for is another story. The only time you could ever justify using a flare gun as a weapon, is when you’re defending your life/lives of others.

Does the US still use napalm?

Originally Answered: Does the us military use napalm? Technically no, but the U.S. military still has bombs which the average person would call napalm. The MK77 Incendiary bomb it uses a different chemical formula but it works the same. They were used in Operation Desert Storm and Iraqi freedom and in Afghanistan.

How long do underwater flares last?

Furthermore, how long do underwater flares last? Maritime distress signal Handheld flares must burn for at least 1 minute at an average luminosity of 15,000 candelas, while aerial flares must burn for at least 40 seconds with 30,000-candela average luminosity.

What metal catches fire in water?

Magnesium, lithium, sodium, potassium, caesium, and rubidium are all metals that will burn and react with water. Potassium is so reactive with water that it has to be stored in oil because it will react with the moisture in the air.

How long can a flare burn?

10 to 60 minutesPyrotechnic Flares An old-fashioned flare, also known as a fusee, will typically burn for 10 to 60 minutes with a bright red light. They are pyrotechnic devices and are also called highway flares, road flares, or ground flares.

How can flares burn underwater?

How do underwater flares and torches work, when water puts out fires? … The combustible gas, which might be hydrogen or acetylene, depending on the application, can be combined with oxygen gas (the oxidizer) to produce an underwater flame at the tip of the torch.

How hot does fire have to be to burn underwater?

But when ignited with a strip of magnesium and a blowtorch, it yields a molten metal so hot it keeps burning underwater. The red powder in question is thermite, a mixture of finely powdered rust and aluminum that burns at a temperature of over 4,000 degrees Fahrenheit.
