What is the primary source of the sun's energy? Please help, Science Test tommorrow?

Question

Science test tommorrow, please answer

Answer 1

i think its hydroggen gas burning

Answer 2

Hydrogen +Hydrogen +Hot=Helium.

I guess some of the Hot comes from the fusion, or it has to be hot for fusion to occur, or...I don't know why we're not able to create fusion. I guess because we're small and dinky compared to the sun and we're just playing around smashing atoms in giant oval tubes...putting them together is much harder.

But the main source of energy is fusion. I think Keanu Reeves made a movie about fusion. I love my boy Keanu, but assuming I'd buy him as a nuclear physicist shows just how unrealistic fusion is for us to achieve. It's all such a leap of imagination, such suspension of disbelief. If you believe fusion is possible to achieve in a lab, then it's not much more effort to believe Keanu can do it. Sigh.

Nuclear power like on the Simpsons is fission--splitting up nuclei. This creates piles of waste and hot cores and lots of bad nasty. I heard plenty of pro-nuclear propaganda growing up, but I'd still take air pollution over nuclear pollution any day. When Keanu is a nuclear physicist, fusion will be our source of energy.

So Keanu better start hittin' the books, that's what I say.

Answer 3

The intense pressure at the core fuses two hydrogen into helium and one free electron, thus creating a nuclear reaction we call fusion. Two helium atoms will combine to form one oxygen and more free electrons, two oxygen to form one carbon, same thing, two carbon to form iron and that's the end of the road for our star.

We are still burning helium though, it will take many millions of years to get into the iron part.

Answer 4

The energy of the sun comes from nuclear fusion reactions that occur deep inside the sun's core.

Answer 5

Hi. Fusion. Hydrogen fusion which makes helium and all the other elements up to iron. Each step releases energy.

Answer 6

the primary source is most likely gases (more nitrogen) and scientists have not found out what sets it burning.
