Can astronauts smoke cigarettes in space?
Well astronauts are not allowed to smoke in space craft.
If someone in space craft smokes, he or she will start polluting the air, which may cause suffocating conditions in space crat.
That is leathel for life.
Second thing, smoking need lit up of cigarettes which requied lot of oxygen..
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.
Can fire burn without fuel?
There must be Fuel to burn. There must be Air to supply oxygen. There must be Heat (ignition temperature) to start and continue the combustion process.
Why is Blue Fire the hottest?
Blue flames have more oxygen and get hotter because gases burn hotter than organic materials, such as wood. When natural gas is ignited in a stove burner, the gases quickly burn at a very high temperature, yielding mainly blue flames.
Can fire burn 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.
How does fire burn in space?
In space, fire burns in a sphere because gravity no longer pulls cooler, denser gases down to the base of the flame. Flammable things also combust at lower temperatures in microgravity — something NASA is currently investigating to in hopes of improving fuel efficiency on Earth.
Can you light a match in space?
The ingredients necessary for ignition are oxygen, fuel, and heat. … “The heat is provided by friction created when the match is struck against a surface.” Once the match is lit, however, combustion in the space station will work a little differently because of the way hot air moves in microgravity.
Can fire exist 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 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.
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. … Space flames can also burn at a lower temperature and with less oxygen than fires on Earth.
Can you burn helium?
Helium is a special gas called a Noble Gas, which means it doesn’t burn. When a match is held near a helium-filled balloon, the balloon pops. That’s it. But when a match is held near a hydrogen-filled balloon: BOOM! a real explosion.
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.
