How does a star create such energy?
nuclear fusion
Why is nuclear a form of energy?
Energy is released in nuclear fission and fusion, this is a fact of the physics of the nucleus. This energy can be captured and harnessed as thermal energy (heat)
What is main disadvantage of fusion?
It requires almost as much energy to create nuclear fusion as the energy it creates. :)
What does nuclear energy transform to?
Nuclear energy transforms to thermal energy (through nuclear fission or nuclear fusion). Thermal energy transforms into kinetic energy (eg produces steam that drives steam turbines). The kinetic energy transforms into electric energy (through electric generators).
How does the sun have thermal energy?
The Sun gets of its energy from nuclear fusion - converting hydrogen-1 into helium-4.
Is fusion nuclear energy or chemical energy?
Nuclear fusion produces nuclear energy
How does the sun create energy it is core?
Nuclear Fusion from hydrogen in it core and helium
How does the sun produce radiant and thermal energy?
The Sun gets its energy from nuclear fusion - converting hydrogen-1 into helium-4.
Outline on nuclear energy?
Definition: energy from nuclear fission or fusion: the energy released by nuclear fission or fusion
How does sun produce thermal energy?
The thermal energy in sun is produced due to the process of nuclear fusion in which two hydrogen atoms combine to form one helium atom.
Is thermal physics related to nuclear power?
Nuclear fusion produces energy because the binding energy of the nucleons in the resulting nucleus is greater than in the starting nuclei. The same happens when a heavy nucleus, U235 or Pu239 for example, splits up. These are both examples of nuclear energy, but as we have not yet learned how to use fusion for power production, useful nuclear energy on earth is only available from fission.
Which two energy sources can help a star maintain its internal thermal pressure?
nuclear fusion and gravitational contraction
