Give definition for nuclear energy?
The energy released by either nuclear fission or nuclear fusion.
What are two ways that fusion is different from fission?
Fusion is bringing two lighter nuclei together and make it one heavier nucleus. Fission is breaking a heavier nucleus and two lighter nuclei are formed. Fusion is going on in the Sun and Stars. Fission is taking place in nuclear reactor In case of fusion no chance of getting harmful radiations, hence known as clear energy. But energy produced per one fusion will be very low and that will be nearly 25 MeV. But fission gives out radioactive materials and so they would give out harmful radiations. But energy per fission will be appox 200 MeV. Hydrogen bomb is an example for fusion process Atom bomb is an example for fission process.
How do you compare fission and fussion?
With nuclear fission, a large atomic nucleus (such as a uranium nucleus) breaks apart into smaller nuclei, and energy is released. With nuclear fusion, small atomic nuclei (such as hydrogen) join to become larger nuclei, and energy is released. Fusion of hydrogen releases much more energy than any other type of either fusion or fission. Note that the dividing line between heavy nuclei and light nuclei is the iron nucleus, which is at the perfect point of nuclear stability, so that neither fusion nor fission of iron nuclei would release any energy.
What is the same with nuclear fission and nuclear fusion?
They are quite different, it's hard to think of anything the same. Different fuel, different conditions to make the fuel give energy. Both types of reaction give out neutrons, so that is one thing the same.
How efficent is nuclear fission?
It is not possible to give an answer as there is no practical design for a fusion power plant. So far scientists have been struggling just to achieve fusion in experimental apparatus. How the energy would be extracted if and when fusion can be achieved is not known, and to get an idea of its thermodynamic efficiency you would need to know this.
Is the nuclear reaction that takes place in a nuclear electrical generating plant exothermic?
I would imagine it is since the goal of an electric plant is to give off energy, and exothermic reactions release entergy. Both fusion and fission, the two major nuclear reactions, are exothermic.
What is nuclear fission and fusion?
Nuclear fusion is the joining up of two smaller nuclei into one larger, in our sun it is the fusion of hydrogen which produces helium, and releases energy. Nuclear fission is the splitting of the nucleus of uranium which releases energy, as in a nuclear reactor.
With Chemical Reactions Fusion and Fission what is the order of their energy output?
1 kg of uranium235 will give as much energy as 1,500,000 kg of coal, so that indicates the difference between nuclear and chemical reaction output. Fusion gives a bit more per kg of fuel than does fission-but we don't know how to use it yet.
What give stars its energy?
Nuclear fusion.
All things contain some nuclear energy?
Einstein showed that all matter is equivalent to energy, and deduced the equation E = mc2. However getting matter to give up this energy requires the right matter and the right conditions. We know there are two ways to obtain it, by fusion and by fission. Fusion is the way the stars produce energy, and this can be made to happen with light elements, isotopes of hydrogen are the easiest to activate. Fission happens with heavy elements like uranium and plutonium, and releases energy we can use in power plants.
How does the sun give renewable energy?
Nuclear Fusion
How does sun give you energy?
Sun provides us energy by process of nuclear fission reaction.
