It is known that there is no air in space. Then how does the SUN burn without oxygen?

Answer 1

Sorry, but that is not true. there is air in space too, however this is the fact that in the air outside our atmosphere the oxygen is not available.

The reason of the energy of sun and the starts is the nuclear fusion of hydrogen and helium atoms which is available in very high amount near sun.

Based on Einstein’s famous equation, e=mc2, he demonstrated that if one could somehow force the protons present in the nuclei of four pounds of hydrogen together to form helium nuclei, the resulting mass of helium would weigh only 3.97 pounds. The difference in mass would be converted to energy, exhibiting itself as heat and light. While many of Eddington’s contemporaries thought his theories were nonsense, he was eventually found to be correct. What he called the transmutation of elements, we call nuclear fusion, which we now know to be the energy source of the Sun.

Answer 2

The nuclear reactions in the sun create oxygen as a byproduct along with other elements. Oxygen is always required for combustion. and no, there is definitely no air in space, it is a vacuum

Answer 3

The sun doen't "burn" in the same way that wood or coal burns. Hydrogen gas is compressed at the center of the sun until it fuses into helium, releasing energy.

Look up any article on nuclear fusion for a further explanation. Here's a starter:

Answer 4

The sun's fire is not burning on oxygen, but on the gases created by the sun's core. It's not burning like our fires, and that's evidenced by the extreme heat it creates in comparison to our puny oxygen fires. And while there is no air in space, there are various gases and chemicals floating around, so theoretically you could have a fire; oxygen is not the only flammable chemical.

Answer 5

The sun burns by a process of nuclear fusion, using hydrogen, not oxygen, as an energy source. It is the same process that a nuclear fusion bomb uses, but on a much larger scale.

Answer 6

Answer: The sun is like a continuously exploding H-bomb: it burns
by thermonuclear fusion reactions, that is, it emits energy
by fusing hydrogen nuclei into helium nuclei. You're right,
space doesn't have
Oxygen, that's why airplanes can't fly into space and
astronauts have to wear spacesuits.

Answer 7

The sun gets its power from nuclear chain reaction - not by combustion that requires oxygen.

Answer 8

there is not any elementary answer to that query. Pedantically conversing, area itself has no temperature - products in area might have temperatures, yet they are able to variety extensively whether the products are purely inches aside. on the earth, there is an ambient air temperature, which products will graduate in direction of if left to themselves (out of the sunlight). that's what meteorologists recommend by employing "the" temperature. In area, there is not any air, so the only way for products to alter temperature is by employing radiating warmth. there's a undeniable quantity of incoming easy and warmth, and the article emits infrared easy as a effect of its very own temperature - bigger temp, extra infrared easy. The temperature will progressively replace till the two quantities are in stability, it quite is customary as equilibrium. If a spacecraft isn't in direct image voltaic, the only incoming radiation is the stars (which we are able to forget approximately approximately) and the elementary "black" of area, which easily supplies off a faint microwave radiation. in terms of temperature, this radiation has a temperature of roughly 3 stages above absolute 0. i might call that chilly. If there is something close by radiating, such by way of fact the sunlight, a undeniable quantity would be contemplated, and could no longer influence the spacecraft. something will pass to heating the spacecraft on the part grew to become in direction of the sunlight. If the article is a incredibly good thermal conductor, the excellent floor will then emit infrared easy. by employing picking how reflective the spacecraft is designed to be, you are able to % the equilibrium temperature. in maximum circumstances, designers %. a severe reflectivity, so as that the spacecraft won't overheat whilst its very own kit is working. the same technique happens with spacesuits, it quite is why they are all lined with an outer layer of extremely-white fabric. even with many of the sunshine contemplated, whilst an astronaut is working, the warmth may be extra advantageous than may be comfortable, and the surplus is carried off by employing evaporating water interior the cooling device. you are going to be able to desire to declare that the backpack is sweating.

Answer 9

Because it is an internal combustion that does not require oxygen

Answer 10

Because the explotions (imp) are in the center of the gas mass of the sun.
