Question

What is the source of heat produced by the Sun?

Answer 1

Nuclear reactions in the sun's core send waves of energy flowing to the surface where it is given off as light, heat and other radiation.Details follow.

The extreme heat and pressure in the sun causes hydrogen atoms to fuse into helium,releasing energy.The particles that transport heat energy(called photons) follow a 'random walk' from the centre to the surface of the sun by a combination of convection and radiaton.The transfer of heat energy from the core to the surface can take up to 10 million years

Answer 2

someone's gotta say it.

barely more than a hundred years ago, it was commonly believed that the Sun was a giant ball of burning coal.

yes, coal.

how did it get in the SKY?

Answer 3

The nuclear fusion going on in its core

Answer 4

big energy burning and making fo-tongs and always burning and making gases and hot waters molecules boiling

Answer 5

Nuclear fusion.

The immense heat within the sun causes all those atoms in the core to jiggle around violently. It's so violent that when hydrogen atoms hit each other, they do so with enough force to cause them to fuse into one atom of helium (that's why we call it fusion). When this happens, energy is released in the form of photons--particles of light.

Answer 6

Y!A's spell check is blocking my answer, which gives the name of the Nobel Prize winner who worked this out, and the details.  Go to Wikipedia (which spell check thinks is another error) and look under nuclear fusion.

Answer 7

Nuclear Fusion caused by two elements being crushed together.  

Answer 8

THE CONSTANT COLLISION OF ATOMS CAUSING THEM TO FUSE TO MAKE LARGER ATOMS

Answer 9

The sun is fusing Hydrogen to Helium at its core.  This nuclear fusion is the source of the energy produced.
