Why is there fire on the Sun?

Question

why is it soooo hot.

Answer 1

There is no fire on the Sun. It is thermonuclear reactions that make the sun glow. Similar, but not identical, to the reactions in a thermonuclear bomb (sometimes called a hydrogen bomb). The Sun is basically one giant, natural, hydrogen powered nuclear reactor.

Answer 2

NUCLEAR FUSION!

Nuclear fusion is the process by which multiple nuclei join together to form a heavier nucleus.

In EVERY STAR there are 2 main elements:
HYDROGEN and HELIUM. And our sun is NOT unexception.

In the basic Hydrogen fusion cycle, 4 Hydrogen nuclei (protons) come together to make a Helium nucleus.

Every 5g of hydrogen fusion can light a 100w light bolt for 200 years.

The sun is a huge nuclear reactor.
That is why the sun is "soooo" hot.

Answer 3

The greatest force in the universe is inside each and every atom. Break that atom up and you deliver massive amounts of energy. The sun is doing that all the time due to its massive gravity crushing the atoms in its core.

That energy consists of heat and light. As pointed out above, the sun is a nuclear fusion reactor that is 1.3 million times the size of Earth.

Answer 4

it is hot due to nuclear reactions. hydrogen atoms joining together to form helium atoms. it is the same process used in the hydrogen bomb, but different form that used in the fission bombs (like the ones they dropped on japan in ww2).

the nuclear reactions give off a lot of energy which keeps the sun hot..

there is no actual fire on the sun since fire needs oxygen to burn, all of the heat comes from fusion. it might look like its on fire but it actually isn't.

Answer 5

Why is a philosophical question. Helium and hydrogen gas exploading constantly accounts for the heat.
