how does the sun get it's energy?

Question

plz and a link it's for a science exit project

Answer 1

There's only one way the sun gets its energy. God made it that way. Any other "explanation" is a farcical attempt at explaining God, and no one has been successful at that so far. Put my answer in your science project, and see how dumbfounded your teachers will be. They can't explain God in all His wonder either, and so they'll always accept or prefer a second rate "scientific" answer and downgrade your "God" answer. Oh well. Some people never learn. God Bless you.

Answer 2

From Hydrogen !
Hydrogen is created by a process called Nuclear fusion & Nuclear fission . The sun inside is like a power plant actually .

Nuclear Fission... occurs when a neutron splits the nucleus of a large atom, such as U 235 , into two smaller nuclei, releasing energy and additional neutrons. The extra neutrons then split other nuclei, producing still more neutrons that split more nuclei, and so on. This process is called a nuclear chain reaction. Causing the sun to constantly burn .

Nuclear Fusion .. A way to create energy by combining the nuclei of light atoms into heavier ones. A common example is fusing hydrogen to form helium. The result is slightly less massive than the sum of its parts. This ‘missing mass’ is released as energy. This is the way the Sun produces energy .

Answer 3

A process called hydrogen fusion.

Hydrogen fusion occurs when hydrogen atoms are combined to form hydrogen gas. This process leaves some energy behind which is thrown off as heat and light (2 forms of energy). A lot of energy is created.

This process is very different than atomic fission where atoms are split. This is how a nuclear reactor works.

Fusion is not something which is a practical form of energy yet. When it becomes one we will have solved the energy crisis because much hydrogen is available from water and that is what a fuion reaction requires.

Nuclear fission requires uranium or plutonium and there is not much of that lying around.

Answer 4

Nuclear fusion reactions in its core fuse hydrogen into helium. Each second, more than 4 million tonnes of matter are converted into energy within the Sun's core, producing neutrinos and solar radiation. In about 5 billion years, the Sun will evolve into a red giant and then a white dwarf, creating a planetary nebula in the process.

Answer 5

Not going into full depth.......

The Sun gets it's energy from a recycled system of Thermo-Nuclear Fusion. Basically, it uses two real primary gases, Hydrogen and Helium. It breaks down Helium into Hydrogen and then back again.
This is done by a passing of sub-atomic particals, because Helium and Hydrogen have relatively the same amout of sub-atomic particles. Since Helium is atomically heavier than Hydrogen, Primarily the Hydrogen particals are pushed toward the surface. This is also in part where radiation comes from. During this process some of the sub-atomic particals are lost. Since (sub)-atomic particals are smaller than atoms, they can pass between them. That's why you get genetic damage and other dangerous side-effects from exposure to radiation, basically. Fusion is the combination of atoms and Fission is breaking them apart.

Answer 6

The sun gets its energy by converting atoms of hydrogen into atoms of helium. This type of energy is called "thermonuclear energy," and it is the same thing that powers the H-bomb. The sun is a nuclear furnace that converts one type of atom into another, releasing energy in the process. Eventually, the atoms will be converted to iron, from which no more energy can be released.

I don't have a link for this but any encyclopedia will give you good detailed information.

Answer 7

The most efficient chemical reaction is combining two hydrogen atoms and one oxygen atom to make a water molecule plus some energy. Such a reaction has a very small ``efficiency'' (something like 1/66000000 of one percent). The efficiency = amount of energy released/(mass× c2), where ``mass'' is the total mass of all of the atoms involved and c is the speed of light. The amount of energy the Sun has stored = the efficiency × (the mass of the fuel source) × c2.

Answer 8

The Sun, like all other stars, gets its energy through nuclear fusion. At its core, where high pressure and temperature cause particles to collide frequently, hydrogen nuclei are fused together into helium nuclei, slightly reducing their mass and converting this mass (through E=mc^2) into radiation. The Sun has enough hydrogen to continue this process of fusion for about 9 billion years. It is currently about halfway through its lifetime, and so will last about another 4.5 billion years.

Answer 9

Fusion Reactions

Answer 10

Hydrogen atoms get mashed together so hard by the force of the sun's gravity that they 'pop' into helium atoms and give of lots of ebergy in the process. It's called Nuclear Fusion and no one has been able to make it work here on Earth yet.

Answer 11

The Sun is a ball of gas and nuclear reactions are taking place in it all the time. As atoms are split apart so energy is released. The conversion of matter into energy releases enormous amounts of energy and these conversions are happening all the time in the Sun.
