why does the sun get so hot?

Answer 1

WHAT (Watt) was that explanation. Lava? I don't believe some of you pay any attention in school.
The sun is so hot because of Hydrogen Fission. That's it. No lava. Just a big ball of hydrogen burning a very long ways away. Actually, it's really kind of small by celestial standards.

Answer 2

The sun is hot because of the incredible pressure created by all that mass. At those pressures, hydrogen atoms (the simplest form of matter) can't exist and are fused (squeezed) together. Four atoms of hydrogen are fused into one atom of helium, the second simplest form of matter. If you weigh four hydrogen atoms you'd find they weigh slightly more than one atom of helium. Since mother nature doesn't allow loose pieces of atoms to just lie around cluttering things up this little bit of extra mass is turned to energy. Over about a million years this energy seeps up through the sun until it reaches space where it escapes as heat and light. It's reckoned that the temperature at the sun's core is around 100 million degrees F but at the sun's surface it's a mere 6000 F.

Answer 3

The sun is made of molten lava. The reason we (the earth) has been getting hotter in the last couple of decades is because the ozone used to protect us from the suns heat and radiation. because of aerosol sprays and toxic gases from gars and engines and smoke stacks we have put major holes into this protective layer of ours and now we are paying the price for it. In the years to come it will get even hotter and then we will have yet another Ice Age. You would think man has learnt from the past but oh no and here it goes again (sigh)

Answer 4

Its not fission ...its FUSION ...hydrogen molecules combile to form Helium which is an inert gas. The Reaction produces incredible energy.

Fission is what we do at the nuclear reactors on earth :)

Answer 5

coz it's hot so hottttttttttt

Answer 6

cause it is made of fire.
