How Can The Sun Burn Without Oxygen?

Complete step by step answer:

But the burning of the sun is not a chemical combustion it is a nuclear fusion. The sun is considered as the giant hydrogen bomb. In the nuclear fusion the nuclei of the atoms fused with each other to form a larger nuclei. The nuclear fusion does not involve oxygen.

How does the sun keep burning?

The sun like the rest of the universe is made mostly of hydrogen. 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.

Is there anything that can burn without oxygen?

2/ You can get fire (flame: light plus heat) without any oxygen for example by burning copper in an atmosphere of chlorine gas. If you mean Fire as combustion i.e. burning something like Petrol paper or cloth yes it needs oxygen to convert fuel content to energy which is basically any organic compound.

Can the sun burn out?

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. … Astronomers estimate that the sun has about 7 billion to 8 billion years left before it sputters out and dies.

When will the Earth explode?

about 7.5 billion years

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.

Can we survive without sun?

All plants would die and eventually all animals that rely on plants for food — including humans — would die too. While some inventive humans might be able to survive on a Sun-less Earth for several days months or even years life without the Sun would eventually prove to be impossible to maintain on Earth.

Does acetylene burn without oxygen?

Decomposition is a chemical reaction whereby acetylene breaks down into its constituent elements carbon and hydrogen. This reaction gives out a great deal of heat which can cause the gas to effectively ignite without the presence of air or oxygen.

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.

Do electrical fires need oxygen?

Turning off the electricity in an electrical fire removes the ignition source. … Without sufficient oxygen a fire cannot begin and it cannot continue. With a decreased oxygen concentration the combustion process slows. Oxygen can be denied to a fire using a carbon dioxide fire extinguisher a fire blanket or water.

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.

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.

Will the Sun explode or implode?

The Sun as a red giant will then… go supernova? Actually no—it doesn’t have enough mass to explode. Instead it will lose its outer layers and condense into a white dwarf star about the same size as our planet is now. … A planetary nebula is the glowing gas around a dying Sun-like star.

How long will humans last?

Humanity has a 95% probability of being extinct in 7 800 000 years according to J. Richard Gott’s formulation of the controversial Doomsday argument which argues that we have probably already lived through half the duration of human history.

Will humans ever leave the Milky Way?

So to leave our Galaxy we would have to travel about 500 light-years vertically or about 25 000 light-years away from the galactic centre. We’d need to go much further to escape the ‘halo’ of diffuse gas old stars and globular clusters that surrounds the Milky Way’s stellar disk.

How long will the earth live?

But no matter what a cataclysmic event 1 billion years from now will likely rob the planet of oxygen wiping out life. Life is resilient. The first living things on Earth appeared as far back as 4 billion years ago according to some scientists. At the time our planet was still being pummeled by huge space rocks.

What if the sun disappeared for 5 seconds?

Consider this: if the sun was to disappear for exactly five seconds it would be 8.2 minutes AFTER the fact before anyone on Earth would even know that it had happened so by the time we were aware the event would have passed.

What if the sun went out for 24 hours?

With no sunlight photosynthesis would stop but that would only kill some of the plants—there are some larger trees that can survive for decades without it. Within a few days however the temperatures would begin to drop and any humans left on the planet’s surface would die soon after.

What would happen if no moon?

The moon influences life as we know it on Earth. It influences our oceans weather and the hours in our days. Without the moon tides would fall nights would be darker seasons would change and the length of our days would alter.

What is the hottest torch?

The Bernzomatic TS8000BT High Intensity Torch Head is the hottest buring torch in the Bernzomatic line.

Can a cigarette ignite acetylene?

Ignition of gases and vapours by lighted cigarettes. … They also tried without success to ignite natural gas (mostly methane) butane and acetylene. Carbon disulphide acetylene ethylene oxide hydrogen sulphide and hydrogen phosphide were readily ignited.

Can oxygen cause a fire?

Oxygen is not flammable but it can cause other materials that burn to ignite more easily and to burn far more rapidly. The result is that a fire involving oxygen can appear explosive-like.

Is salt water flammable?

Seawater/ saltwater is not flammable and will not catch fire. It could even be used to put out fires the same as freshwater. … Though technically if you can make water hot enough to split into its two individual elements hydrogen and oxygen – they are flammable.

Can water make fire bigger?

Water does not extinguish Class B fires and can spread the flammable liquid making it worse. You must only put out these fires with powder foam or carbon dioxide extinguishers to cut off the fire’s oxygen supply.

Can water start a fire?

No your refreshing glass of water won’t spontaneously combust. Water is made up of two elements hydrogen and oxygen. Hydrogen is flammable but oxygen is not. … You can’t burn pure water which is why we use it to put out fires instead of starting them.

What fire needs to burn?

Oxygen heat and fuel are frequently referred to as the “fire triangle.” Add in the fourth element the chemical reaction and you actually have a fire “tetrahedron.” The important thing to remember is: take any of these four things away and you will not have a fire or the fire will be extinguished.

What is the best Defence against fire?

Replace your extinguisher if it cannot be recharged. As always the best defense against a fire is to be prepared. Take a moment to look at your fire extinguisher.

How old is the earth?

4.543 billion years

What will happen earth?

Several billion years from now a red-giant Sun will consume the inner planets as it expands. Earth might escape incineration but the temperature increase will boil the oceans and scorch the land. There are few topics of greater interest and intrigue to everyone who has ever contemplated the cosmos.

What will Earth be like in 2025?

The world’s population is expected to grow to around 8 billion by 2025. … By 2025 some 3 billion people will live in land-short countries and another 2 billion will be living in urban areas with high levels of air pollution.

Can a wormhole exist?

In the early days of research on black holes before they even had that name physicists did not yet know if these bizarre objects existed in the real world. The original idea of a wormhole came from physicists Albert Einstein and Nathan Rosen. …

Will Earth end up in a black hole?

Will Earth be swallowed by a black hole? Absolutely not. While a black hole does have an immense gravitational field they are only “dangerous” if you get very close to them. … It would get very dark of course and very cold but the black hole’s gravity at our distance from it would not be a concern.

Will the sun swallow the Earth?

The Sun would be larger than Earth’s orbit. It would swallow the planet whole. Once it’s inside the Sun’s atmosphere Earth would collide with particles of gas and spiral inward.

What will happen in 100 trillion years?

And so in about 100 trillion years from now every star in the Universe large and small will be a black dwarf. An inert chunk of matter with the mass of a star but at the background temperature of the Universe. So now we have a Universe with no stars only cold black dwarfs. … The Universe will be completely dark.

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.
