Actually it doesn't. In nuclear reactions, both mass and energy are conserved. Taking the Sun as an example:
Mass: The light that leaves the Sun has a mass.
Energy: The energy emitted by the Sun existed before the nuclear reaction, in the form of potential energy (nuclear energy in this case).
The mass of a body can get converted into energy according to Einstein's famous equation, E=mc^2. This equation states that energy (E) is equal to the mass (m) of an object multiplied by the square of the speed of light (c). Essentially, this means that even a small amount of mass can release a large amount of energy when it is converted through nuclear reactions or other processes.
Yes. In a way, energy and mass are closely related; energy HAS mass, mass HAS energy. Energy gets converted into mass routinely in particle accelerators. The kinetic energy from the moving particles gets converted into new particles.
for both fission and fusion is E=Mc2 energy is mass and vise verse, in both fission and fusion some mass gets lost in the process. this mass gets converted to energy.
None. There is no such thing as mass-to-energy conversion: both mass and energy are conserved! The total mass before and after a nuclear reaction is the same; so is the total energy. For more information, read the Wikipedia article on "binding energy".
its converted to energy
Kinetic energy is the energy in a mass of matter that is in motion, the energy of motion. Potential energy (where mass is in a gravity field) can be converted into kinetic energy Chemical energy (of an explosion) can be converted into kinetic energy Electrical energy can be converted into kinetic energy (eg in an electric motor)
Mass can be converted to energy in some very special cases, but no general method to convert any mass directly into energy is known.
Energy is relates when hydrogen is converted into helium in the sun's core.
The only condition where mass can be extinguished is if it is converted into energy. When this happens it obeys the well known equation E=mc2
Depends, what do you mean "change"? Atomic mass "changes" whenever something undergoes decay or breaks apart. In this respect, atomic mass is not exactly conserved either. Rest mass gets converted to energy; e=mc^2, meaning energy is equal to mass times the speed of light squared. This energy is usually the kinetic energy of the particle that gets dislocated from the original atom.
Sure, burn it.
The principle of mass conversion to energy. The mass loss (due to nuclear fission or nuclear fusion) is converted to thermal energy. The thermal energy is converted (through turbines) to mechanical energy. The mechanical energy is converted (through electric generators) to electrical energy.
its not about stars its about mass and he proposed that mass can be converted into energy
