Can a fire burn forever?
“As long as there is a fuel supply and oxygen to supply it, a fire can burn indefinitely,” said Steve Tant, policy support officer for the Chief Fire Officers’ Association operations directorate.
“They have the right conditions, particularly if they are on a coal seam where there is a constant fuel source..
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.
What happens when you heat a vacuum?
If you try to heat an object in vacuum, it will heat up a bit, but soon it will start emitting this heat in the form of infra-red rays. Consider this analogous to earth – it receives heat from sun and emits heat to the universe which is at 2.7 deg Kelvin* in the form of infra-red rays.
How does fire burn in space without oxygen?
Without gravity, hot air expands but doesn’t move upward. The flame persists because of the diffusion of oxygen, with random oxygen molecules drifting into the fire. Absent the upward flow of hot air, fires in microgravity are dome-shaped or spherical—and sluggish, thanks to meager oxygen flow.
Can a gun fire underwater?
Because standard bullet ammunition does not work well underwater, a common feature of underwater firearms is that they fire flechettes instead of standard bullets. … Rather, the fired projectile maintains its ballistic trajectory underwater by hydrodynamic effects.
Are there any bodies in space?
In the last half-century, about 30 astronauts and cosmonauts have died while training for or attempting dangerous space missions. … However, of the roughly 550 people who have so far ventured into space, only three have actually died there.
What would happen if you shoot a bullet in space?
Bullets shot in space wouldn’t really travel any faster than they would on Earth, though they could travel farther. … In space, where there is no gravity, your bullet could keep moving forever as long as it doesn’t hit something — like an asteroid or a planet.
Can you light 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.
What happens to wood in space?
Wood would not rot in space. … Any water in the wood would flash boil, and the wood would be left bone dry and husk like, if it was even still in one piece. With no water or air, even bacteria that might have been able to live off of just the wood will quickly lose a lot of their ability to metabolize.
What Cannot be burned by fire?
What can’t be burned in a fire nor drowned in water? Ice. It melts instead of burning in a fire and it floats in water. Ice.
Will a Glock fire underwater?
Glock has a modification to their guns that allows for them to shoot more easily underwater. There is a video showing someone hunting lionfish in Florida with such a Glock. Of course, the gun must be very, very close to the fish to work.
What guns do snipers carry?
What Weapons Do Snipers Carry? The 338 sniper rifle is the vital firearm for any sniper and is the primary weapon system for long-range shooting. The troops use an 8.59mm calibre rifle which has a magazine of five rounds and can accurately hit targets from 900 metres away and “harass” up to 1,500 metres.
What does space smell like?[like] … sweet-smelling welding fumes’, ‘burning metal’, ‘a distinct odour of ozone, an acrid smell’, ‘walnuts and brake pads’, ‘gunpowder’ and even ‘burnt almond cookie’. Some astronauts have likened the smells of space to walnuts. … It may be this, and not an interstellar aroma, that astronauts are smelling.
Is Burning possible without oxygen?
No and Yes. No combustion I S combination with oxygen. There are products that under the right circumstances can ‘ burn’ or even deflagrate or explode, without there is oxygen gas ( in air) available. then oxygen must be available within the component(s) them self.
What is the burning point of wood?
Most types of wood will start combusting at about 300 degrees Celsius. The gases burn and increase the temperature of the wood to about 600 degrees Celsius (1,112 degrees Fahrenheit). When the wood has released all its gases, it leaves charcoal and ashes.
Can you have a fire in a vacuum?
You could not just pull out a lighter and start something on fire in space like you could on earth because combustion requires oxygen. … Fire however, does not usually occur in space. It is a special case though that would almost certainly have to be done intentionally by humans.
Can wood burn in a vacuum?
Wood starts to burn at 450°F (233°C). In space, all the moisture in the wood will be sucked out by the vacuum of space. When facing the sun, the skin will heat up to 250°F (121°C) and on the shaded side, cool to -250°F (-157°C). Some cracking will definitely occur.
Can a fire burn without oxygen?
Technically the answer is no. The definition of fire, in the presumed sense of combustion or burning, is “combustion or burning, in which substances combine chemically with oxygen from the air and typically give out bright light, heat, and smoke,” according to Google. So without oxygen it would not be fire.
What is the longest burning fire in history?
Fueled by coal seams A coal seam-fueled eternal flame in Australia known as “Burning Mountain” is claimed to be the world’s longest burning fire, at 6,000 years old. A coal mine fire in Centralia, Pennsylvania, has been burning beneath the borough since 1962.
What is the hottest fire color?
Color also tells us about the temperature of a candle flame. The inner core of the candle flame is light blue, with a temperature of around 1800 K (1500 °C). That is the hottest part of the flame. The color inside the flame becomes yellow, orange, and finally red.
Can AK 47 fire underwater?
How firing an AK47 underwater can actually make it work BETTER: Enthusiast proves not only does weapon fire while submerged, it reloads faster. Submerging an AK 47 gun and firing it underwater appears to make it work better, according to high speed footage.
