What Makes The Sun Hot???

Question

ive been wondering for a long time and it is making me soooo mad!!

Answer 1

Wow, we are giving sub-atomic patricles colors now!

That's wonderful, especially since they are smaller than the smallest wavelengh of visible light.

I think I better explain how fussion in the sun creates energy a bit better than that so there is no confusion. You can take your pick which answser to believe.

OK, you start with 4 hydrogen atoms, each with one proton and one electron (no neutrons yet). Gravitational pressure at the core of the sun forces these atoms together, and they fuse, leaving you with a helium atom. If you add the mass of the four hydrogen atoms and compare it to the mass of a helium atom, you will have a little bit of mass left over, this mass is converted into energy (not fire, it is way to hot even on the surface of the sun to have fire, and there is no oxygen to aid in combustion, if the sun relied on fire to generate heat, it would have burned out long before life formed on earth, and would not generate enough heat to warm the earth).

Anyway, that is a simplified version of how fusion works, for more information, do a search on nuclear fusion and you will find plenty of sites with more detail. . .

Answer 2

The sun is hot because in the core nuclear fusion is occuring by use of the proton-proton chain. Which is basically the fusing of 6 Hydrogen atoms into 1 Helium atoms, at the end phase however two Hydrogen atoms are given back thereby giving you the usually 4 Hydrogen to 1 Helium conversion rate. Anyway, this fusion takes place due to immense gravimetric pressures that are drawing the gas inward and heating the atoms to the point at which nuclear fusion can occur. The core operates at a temperature of 15 million degrees Kelvin, by comparison our normal room temperature of around 70 degrees Fahrenheit is about 300 degrees Kelvin.

Answer 3

The process is called Nuclear Fusion which is basically taking two smaller atoms, smashing them together and making one big one. Specifically, the sun takes two hydrogen atoms and smash them together to make a helium atom. The problem is that two hydrogen atoms actually make a little bit more than one helium atom so there is something slightly small which is left over. Since that left over is not enough to make another atom, it is released as energy according to Einstein's famous e=mc^2 where e is the energy produced, m is the mass and c is the speed of light.

As you can probably guess that c is actually a very huge number so even a very tiny tiny amount of matter can produce huge amounts of energy which is exactly what happens in the sun. The energy is released as heat, light, sound, and countless other forms which we cannot directly observe such as radiation.

Answer 4

We really dont know how the Sun became a nuclear fusion furnace to producuce radiative heat energy.
When you light a furnace you need activation energy.The activation energy had to have an external source.The Sun"s Nuclear atomic interaction would only occur if a lot of energy was used to star the Nuclear fusion Process.
This is a very inovative question. Its simple but science does not have all the exact answer how the Sun was created to function as it does.

Answer 5

The sun is hot because of the nuclear fusion that takes place in its core. The sun fuses two hydrogen atoms to become one helium atom with a little bit of energy left over. Since the sun is so big (over 300,000 times the mass of earth) the fusion energy puts out a tremendous amount of heat.

Answer 6

The nuclear fusion in the core of the sun creates energy, which is essentially heat. It is about 15 million degrees at its core, and about 6000 degrees on the outer layer (photosphere). The energy travels from the core to the surface (what you could call the surface, as it is all gas and plasma) by radiation and convection. We feel the heat because it travels from there to the Earth via light waves. The higher the energy, the faster the wavelengths (frequency), which translates to more heat.

Answer 7

In the center of the Sun, in its core, nuclear fusion powers the Sun. Hydrogen is converted to Helium, giving off enormous amounts of energy. That energy is transported through radioactivity and convection to the photosphere (the Sun's surface). The energy is released as photons from the photosphere.

Answer 8

The enormous release of energy from nuclear fusion fusing hydrogen into helium at the rate of several million tonnes a second. The sun has been doing this non stop for billions of years and is still 97% hydrogen.

Answer 9

Nuclear Fusion

Answer 10

simply put its an atomic reaction thats releaseing all kinds of radiation in all directions at once the fire actually causes life on earth without thr radiation our plants coundnt grow and produce oxygen for us ,, sounds simple its not also the core of the earth is still hot and thats the magma the crust we live on floats on like volcanoes ok
