How does fire burn in space without oxygen?
But odd things happen in space, where gravity loses its grip on solids, liquids and gases.
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..
Can you light a match in space?
Fire behaves differently in space than it does here on Earth. If you light a match on Earth, the flame is long and pointy because hot gases rise upward from the flame, keeping it straight and sticking up. But in space, buoyancy does not exist — so the flames spread out in all directions.
What happens if an astronaut rips his suit?
If there is a cut in the space suit, then the worst nightmare of an astronaut has come true. The suit will quickly depressurize making the oxygen escape from it, and needless to say within a minute, the astronaut will be far away from retrieval of life in himself.
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.
Will a gun fire underwater?
The bullet casing is waterproof, so when it collides with the firing pin it causes the gun to ignite, regardless if it is underwater. But water is 800 times denser than air, which hinders the bullet from traveling far and fast. Compared to air, water has more resistance and holds the bullet back from doing any damage.
What does space smell 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. Image source: LubosHouska; CC0.
Can matches catch fire in heat?
Match heads are coated in phosphorous based compounds that catch fire when heated up. … Early “strike anywhere” matches were coated in white phosphorous, but the white phosphorus was too easy to light. This made them rather dangerous, as they tended to ignite accidentally.
Would a fire extinguisher work in space?
Sure. A fire extinguisher makes a perfectly good, if low thrust, rocket. Indeed, when astronaut Ed White performed the first American spacewalk in 1965, on Gemini 4, he used a little oxygen gun in much this way. … A fire extinguisher makes a perfectly good, if low thrust, rocket.
Can you breathe in space?
There’s no air in space (it’s kind of part of the definition), which means there’s no oxygen. But your blood doesn’t know that.
Does the sun need oxygen to burn?
The Sun does not “burn”, like we think of logs in a fire or paper burning. The Sun glows because it is a very big ball of gas, and a process called nuclear fusion is taking place in its core. … Hydrogen really doesn’t burn, it fuses, into helium. So no oxygen is required!
Can you light fire on the moon?
Fire can not be lit on the moon because there is no oxygen there. without one of these elements it is impossible to lit fire.
Can you have 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.
Can you shoot a gun on the moon?
Yes, you can fire a gun on the Moon, despite the absence of oxygen. A gun “fires” because of a sudden impulse delivered to the gunpowder by the trigger. … Despite the abundance of oxygen on Earth, however, most gun ammunition comes with its own oxidizer “built in”, so to speak.
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.
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.
What happens if you light fire in space?
When flames burn on Earth, heated gases rise from the fire, drawing oxygen in and pushing combustion products out. In microgravity, hot gases don’t rise. … Space flames can also burn at a lower temperature and with less oxygen than fires on Earth.
Can a body decompose in space?
If you do die in space, your body will not decompose in the normal way, since there is no oxygen. If you were near a source of heat, your body would mummify; if you were not, it would freeze. If your body was sealed in a space suit, it would decompose, but only for as long as the oxygen lasted.
How fast can a bullet go in space?
0.62 mile/secWell, it would simply drift into the blackness, forever alone, while the galaxies around it sped further away. Those galaxies are travelling at around 200km/s (124 miles/sec) as the Universe expands, whereas a travelling bullet can reach speeds of only 1km/s (0.62 mile/sec).
