Question: Can You Have A Fire In A Vacuum?

Will magnesium burn in a vacuum?

Since there is no water in space to supply the oxygen, then magnesium will not burn in space, (and nothing else will, either) unless some sort of oxidizer is provided..

Can a gun fire 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.

Does magnesium burn underwater?

Magnesium fires cannot be extinguished by water. Magnesium continues to burn after oxygen is depleted. … When attempts are made to extinguish magnesium fires with water, magnesium aggressively reacts with hydrogen gas. To prevent any damage, a magnesium fire must be covered in sand.

Are there any human bodies in space?

The resulting drop in pressure also exposed the crew to the vacuum of space — the only human beings to ever experience such a fate. They died within seconds of the rupture, which occurred at 168 kilometers (104 miles), making them the only human beings to die in space.

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.

Can astronauts cry in space?

There’s no crying in baseball, and now there’s no crying in space. While the zero gravity atmosphere does not have an impact on tears forming, it has an affect on if they fall, and they don’t.

Is it harmful to kiss a smoker?

Tar stained teeth, and an increase in tooth loss and gum disease might get his attention, not to mention kissing a smoker is like licking an ash tray. There is an increase risk for other cancers including cervical, bladder, kidney, pancreas, mouth and throat cancer.

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

Is it possible to smoke in space?

Outside of Earth, these rays are free of any magnetic force, which can then affect sleep, mood, appetite, energy level, and memory just like cannabis, so smoking in space would only mess with the unique high experience associated with marijuana. …

What happens if there is a fire in space?

Fire is a different beast in space than it is on the ground. 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. … As a result, the material used to put out space fires must be more concentrated, researchers said.

Can u get pregnant in space?

As a result NASA’s official policy forbids pregnancy in space. Female astronauts are tested regularly in the 10 days prior to launch. And sex in space is very much frowned upon. So far the have been no confirmed instances of coitus, though lots of speculation.

Can you bleed in space?

In space, blood can splatter even more than it usually does on Earth, unconstrained by gravity. Or it can pool into a kind of dome around a wound or incision, making it hard to see the actual trauma. (Fun fact: If you are bleeding more than 100 milliliters per minute, you are probably doomed.

Do smokers know how bad they smell?

2. Sense of smell and taste. Smelling like an ashtray isn’t the only impact smoking has on the nose. Smokers also experience a dulling of their senses; smell and taste in particular take a hit when you smoke.

Why does smoke float?

Because usually, there is a fire that produces the smoke. This fire generates heat, increasing the temperature of the surrounding air. Now hot air is lighter than cold air, and begins to rise upwards. This rising air pushes the solid particles upwards against gravity.

What temp does magnesium ignite?

Flammability. Magnesium is highly flammable, especially when powdered or shaved into thin strips, though it is difficult to ignite in mass or bulk. Flame temperatures of magnesium and magnesium alloys can reach 3,100 °C (5,610 °F), although flame height above the burning metal is usually less than 300 mm (12 in).

Do you age differently in space?

So depending on our position and speed, time can appear to move faster or slower to us relative to others in a different part of space-time. And for astronauts on the International Space Station, that means they get to age just a tiny bit slower than people on Earth. That’s because of time-dilation effects.

Can astronauts fart in space?

But if you’re an astronaut, every fart is a ticking time bomb. The gases in farts are flammable, which can quickly become a problem in a tiny pressurized capsule in the middle of space where your fart gases have no where to go.

How do you get fire smoke out of your lungs?

How can you care for yourself at home?Get plenty of rest and sleep. … Suck on cough drops or hard candy to soothe a dry or sore throat. … Take cough medicine if your doctor tells you to.Do not smoke or allow others to smoke around you. … Avoid things that may irritate your lungs.More items…

What happens to smoke in a vacuum?

A spaceship orbiting earth is moving fast enough to break gravity and the vacuum of space has no density. In this case the smoke may expand in all directions, or the direction of force applied by an explosion and continue moving at the same direction and velocity of the object that created the ‘burn’ process.

Can you smoke a cigarette in space?

Originally Answered: Can you smoke cigarettes in outer space? Combustion of tobacco could be supported in any spacecraft designed to support human life outside of pressurized suits. Doing so, however, would be an extraordinarily bad idea. In a 100 percent oxygen atmospheres it would quite possibly be suicidal.

Why does magnesium catch on fire?

When magnesium interacts with water, it will form a hydrogen gas that ignites violently due to the excessive heat and oxygen supply. When it reacts, it will burn hot enough to decrease the water molecule, which turns to a Hydrogen Gas.

Will a gun fire underwater?

Design. Because standard bullet ammunition does not work well underwater, a common feature of underwater firearms is that they fire flechettes instead of standard bullets. The barrels of underwater pistols are typically not rifled.

Can you breathe in space?

Whatever you do, don’t hold your breath! The vacuum of space will pull the air from your body. So if there’s air left in your lungs, they will rupture. … Without air in your lungs, blood will stop sending oxygen to your brain.

Who owns the moon?

The Outer Space Treaty means therefore that – no matter whose national flags are planted on the lunar surface – no nation can ‘own’ the Moon. As of 2019, 109 nations are bound by the Treaty, and another 23 have signed the agreement but have yet to be officially recognised.

Can astronauts drink alcohol in space?

“Alcohol is not permitted onboard the International Space Station for consumption,” says Daniel G Huot, spokesperson for Nasa’s Johnson Space Center. “Use of alcohol and other volatile compounds are controlled on ISS due to impacts their compounds can have on the station’s water recovery system.”
