If There Is No Oxygen In Space How Does The Sun 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!
How does the sun keep burning?
The efficiency of thermonuclear fusion is a major reason the sun has kept radiating heat for so long—the energy released by turning just one kilogram of hydrogen into helium is the same as burning 20 000 metric tons of coal.
How can the sun burn in a vacuum?
Since there is a vacuum in space there is no oxygen there so how does the sun burn? It releases energy because of nuclear fusion in it’s core where hydrogen turns into helium. That is how the sun becomes hot amd bright.
Can you burn something without oxygen?
Can a fire burn in a room with no oxygen? A fire cannot burn without oxygen. … The burning that a star does then is a nuclear reaction and not a chemical one like the fires on Earth (when a candle burns the atoms themselves remain unchanged: just the molecules are affected).
What is burning without oxygen called?
The term you are looking for is probably pyrolysis. Pyrolysis is a chemical decomposition reaction involving little to no oxygen or at least not enough oxygen for combustion.
How is space cold?
In space there is no air or water so the only way to lose heat is by radiation where your warm and wiggly atoms release energy directly into space.
For about a billion years the sun will burn as a red giant. Then the hydrogen in that outer core will deplete leaving an abundance of helium. … Once all the helium disappears the forces of gravity will take over and the sun will shrink into a white dwarf.
Why is space so cold when the sun is so hot?
When the sun’s heat in the form of radiation falls on an object the atoms that make up the object will start absorbing energy. … Since there is no way to conduct heat the temperature of the objects in the space will remain the same for a long time. Hot objects stay hot and cold things stay cold.
Why is there no oxygen in space?
We’re able to breathe on earth because the atmosphere is a mixture of gases with the thickest gases nearest the earth’s surface giving us the oxygen we need to breathe. In space there is very little breathable oxygen. … This prevents the oxygen atoms from joining together to form oxygen molecules.
Will the sun explode?
Scientists have conducted a lot of researches and study to estimate that the Sun is not going to explode for another 5 to 7 billion years. When the Sun does cease to exist it will first expand in size and use up all the hydrogen present at its core and then eventually shrink down and become a dying star.
How do things burn in space?
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.
Why doesn’t the sun burn up all at once?
Because the sun doesn’t burn at all. … There isn’t enough oxygen in the entire solar system to keep the surface of the sun burning through chemical combustion for more than a very short time—probably hours. Instead the sun’s heat and light comes from thermonuclear fusion.
Can fire burn underwater?
Fire requires a combustible substance and oxidizer to ignite. For underwater burning in Baltimore since there’s no oxygen available underwater the torch has two hoses that produce the combustible substance and oxygen gas. With careful application a sustained fire can be created even underwater.
Is the sun made of fire?
No the Sun isn’t “made of fire”. It’s made mostly of hydrogen and helium. Its heat and light come from nuclear fusion a very different process that doesn’t require oxygen. Ordinary fire is a chemical reaction fusion merges hydrogen nuclei into helium and produces much more energy.
Does the sun give us oxygen?
Through nuclear fusion the Sun can (or at the very least someday will) produce atoms of all elements up to and including oxygen. And in terrestrial chemistry at least when you combine oxygen hydrogen and a small amount of heat you get water.
Where does the sun get its fuel?
Nuclear fusion
Nuclear fusion is what happens in the Sun – it’s the combining of light elements into heavier elements to produce energy. The Sun produces a large amount of energy by combining very light elements such as hydrogen to heavier elements such as helium and then lithium oxygen carbon right up to iron.
Answer: That number times 1 hour is 0.0026 seconds. So a person at that deep space location would have a clock that would run for one hour while that person calculated that our clock ran for 59 minutes 59.9974 seconds.
Does your body decay 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 hot is the moon?
When sunlight hits the moon’s surface the temperature can reach 260 degrees Fahrenheit (127 degrees Celsius). When the sun goes down temperatures can dip to minus 280 F (minus 173 C).
What will happen 5 billion years from now?
Five billion years from now the sun will have grown into a red giant star more than 100 times larger than its current size. It will also experience an intense mass loss through a very strong stellar wind. The end product of its evolution 7 billion years from now will be a tiny white dwarf star.
What is the closest body to the earth in space?
Venus
Moon is the nearest celestial body to our earth. Together with the Moon Venus and Mars are the planets nearest to the Earth.
Will the Sun become a black hole?
Will the Sun become a black hole? No it’s too small for that! The Sun would need to be about 20 times more massive to end its life as a black hole. … In some 6 billion years it will end up as a white dwarf — a small dense remnant of a star that glows from leftover heat.
What’s the scariest thing in space?
Supermassive black holes are strange
The biggest black hole discovered so far weighs in at 40 billion times the mass of the Sun or 20 times the size of the solar system.
Would you actually freeze in space?
Acute exposure to the vacuum of space: No you won’t freeze (or explode) … The absence of normal atmospheric pressure (the air pressure found at Earth’s surface) is probably of greater concern than temperature to an individual exposed to the vacuum of space [1].
Why is space silent?
In space no one can hear you scream. This is because there is no air in space – it is a vacuum. Sound waves cannot travel through a vacuum.
What does space smell like?
Astronaut Thomas Jones said it “carries a distinct odor of ozone a faint acrid smell…a little like gunpowder sulfurous.” Tony Antonelli another space-walker said space “definitely has a smell that’s different than anything else.” A gentleman named Don Pettit was a bit more verbose on the topic: “Each time when I …
A total of 18 people have lost their lives either while in space or in preparation for a space mission in four separate incidents. Given the risks involved in space flight this number is surprisingly low. … The remaining four fatalities during spaceflight were all cosmonauts from the Soviet Union.
Is there sound in space?
Space is a vacuum — so it generally doesn’t carry sound waves like air does here on Earth (though some sounds do exist in outer space we just can’t hear them).
What if the Sun turned into a black hole?
What if the Sun turned into a black hole? The Sun will never turn into a black hole because it is not massive enough to explode. Instead the Sun will become a dense stellar remnant called a white dwarf.
How much longer will the Earth last?
By that point all life on Earth will be extinct. The most probable fate of the planet is absorption by the Sun in about 7.5 billion years after the star has entered the red giant phase and expanded beyond the planet’s current orbit.
What if our sun went supernova?
If our sun exploded as a supernova the resulting shock wave probably wouldn’t destroy the whole Earth but the side of Earth facing the sun would boil away. Scientists estimate that the planet as a whole would increase in temperature to roughly 15 times hotter than our normal sun’s surface.
What happens if you light 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.
Do magnets work in space?
Magnets can be used in space. … Unlike a lot of other items you might bring to space that need additional tools or equipment to function a magnet will work without any extra help. Magnets don’t need gravity or air. Instead their power comes from the electromagnetic field they generate all by themselves.
Can a candle burn in space?
Anne Marie Helmenstine Ph. D. A candle can burn in zero gravity but the flame is quite a bit different. Fire behaves differently in space and microgravity than on Earth.
