what is the source of the large amounts of energy released in nuclear reactors and in the sun?

Question

... ARE THE SAME PROCESSES OCCURING IN THE SUN AND THE REACTORS? EXPLAIN

CAN U GUYS HELP ME ...

Answer 1

The majority is partly right here. The predominant reaction in the sun is fusion. There is nuclear fission going on there too, just at a much, much lower level of activity. The commercial power reactors we use for electricity generation use fission. There are some experimental reactors that use fusion, but the reactions aren't yet sustainable. These fusion reactors are far from commercially viable.

Answer 2

The process of fusion in the sun combines small atoms into larger ones, mostly hydrodgen into helium. The process of fission in a nuclear reactor breaks large atoms like uranium or plutonium into smaller atoms.

In both cases, though, the source of energy is the same : conversion of matter to energy. In both fusion and fission, what you have afterwards contains slightly less mass than what you started with, and the difference is released in the form of energy. This is where the Einstein's equation E = mc^2 applies, which basically says that a small amount of matter is equivalent to a large amount of energy.

Answer 3

the source is the lost mass during the reaction. but, the processes r not same. sun uses the fusion reaction while the nuclear reactor uses fission reaction. in the sun, the rection is the fusion of 2 hydrogen atoms results into a helium molecule and large amount of heat is generaed along. whereas in a nuclear reactor , the radioactve element such as uranium is broken into small elements like thorium etc, which is much stable than uranium resulting into the generation of heat.

the lost mass generats energy acc 2 the relation E=mc2 given by Einsetin.

Answer 4

In both cases, the energy comes from the destruction of matter. When converting matter to energy, Einsteins famous equation: E=mc^2 applies. E is energy, m is mass & c is the speed of light. Since light travels at about 3*10^8 m/s, the destruction of a small amount of matter creates a large anount of energy.

The 2 processes are fundamentally different. Nuclear reactors create energy by breaking or fissioninf large atoms such as Uranium into smaller 1's losing a little mass & creating a lot of energy. The sum creates energy by combining or fusing 2 or more small atomes into larger 1's resulting in a small loss of mass & creating a lot of energy.

Answer 5

Large Amount Of Energy

Answer 6

It is pretty much the same process going on in the sun and reactors. It is actually nuclear fussion which is where smaller particles fuse to make larger particles (hydrogens turning into helium, an later helium turning into lithium) that goes on in the sun, whereas you can have both fusion and fission (larger particles breaking into smaller ones) in reactors.

Answer 7

It's nuclear FUSION in the Sun and nuclear Fission here on Earth.

Scientists are trying to develop controlled nuclear fusion here on earth, but so far they have not been successfull at a sustainable reaction that produces more engery than it takes to get it going. If they ever figure it out, fusion holds the promise of a relatively clean and emense source of energy. We can only hope

Answer 8

I can see that one person said the wrong thing the Sun is using Nuclear FUSION, the combing of atoms' nuclei. And nuclear reactors are using Nuclear FISSION, the splitting of atoms' nuclei.

Answer 9

In the Sun, it is nuclear fusion. Under high temperature, small nuclei combine to form large nuclei. In nulear reactor, it is nuclear fission, large nuclei split into small ones.

Answer 10

It's fission (from the sun), and nuclear reactions in nuclear reactors is fusion. The suns temps are WAY hotter than nuclear reactors and the Sun is fissioning off hydrogen and the nuke reactors are fusioning plutonium and heavy elements.
