Nuclear fusion requires extremely high temperature and great pressure.
Extremely high! Take her to emergency ASAP!
Only at the core where the temperature and pressure is high enough.
10,000,000 and up.
Nuclear fusion doesn't take place in a white dwarf because the core temperature and pressure aren't high enough to initiate the fusion of heavier elements such as carbon and oxygen. White dwarfs have already exhausted their nuclear fuel and are essentially the leftover cores of stars that have gone through their fusion stages.
Ibuprofen. had a temperature of a high level .Quite frankly, it worked.
Your question expresses a significant bit of conceptual confusion. Perhaps I can clear up some of this confusion and at the same time answer your question.What we call temperature is simply the manifestation of kinetic energy at the level of the atom (i.e. slow moving atoms = low temperature, fast moving atoms = high temperature). What we call nuclear energy is simply an excess in the nuclear binding energy, which is the energy binding the protons and neutrons together inside the nucleus and is a manifestation of the strong nuclear force and to a lesser extent the weak nuclear force. This movement of atoms has no affect at all on whether there is or is not excess nuclear energy inside atomic nuclei or if that excess nuclear energy is being released or even can be released. Those nuclei having the least nuclear binding energy are the nuclei of the elements from iron through lead, both the elements lighter than iron and the elements heavier than lead have more nuclear binding energy (which can be considered to be excess nuclear binding energy that could potentially be released).There are three processes that can release excess nuclear energy: radioactive decay, nuclear fission, and nuclear fusion. All of these processes transform nuclear energy to kinetic energy at the level of the atom (i.e. temperature aka heat), and thereby convert a small amount of the mass of the atom into energy. Of these three both radioactive decay and nuclear fission can take place at any temperature, even those so cold as to approach absolute zero. Neither radioactive decay nor nuclear fission takes place any faster or slower with a change in temperature. Nuclear fusion though can only take place at very high temperatures (and pressures) as the nuclei must be very close together and moving fast enough to be able to collide and fuse, despite the strong electrostatic repulsion due to both nuclei involved being positively charged. But this is a threshold temperature, even at high temperatures just below the threshold no nuclear fusion can take place at all and once above the threshold and nuclear fusion begins, raising the temperature further has very little affect on the rate at which that nuclear fusion takes place.Nuclear reactors operate using the process of nuclear fission and generate heat by both nuclear fission and radioactive decay. We are not yet able to extract nuclear energy in a controlled manner using the process of nuclear fusion (only explosive release of nuclear energy has ever been successfully done using the process of nuclear fusion).
it would weigh around million tons because the whole weight of matter lies in the nucleus of it which is very small if we take many of those nuclei it would weigh about a million tons
Not at all, the temperature of U-235 or Pu-239 which are used for nuclear energy production by fission, has no effect on the fission reaction, which is driven only by the capture cross-section for neutron capture. Slow neutrons are captured more strongly than fast ones, so it is an advantage for the moderator not to be at a high temperature.
High temperature and high pressure are necessary for fusion reactions to take place in a star. The high temperature is needed to overcome the electrostatic repulsion between positively charged atomic nuclei, while the high pressure is needed to confine the high temperature plasma.
No, nuclear fusion does not occur in the convection zone of a star. Fusion reactions primarily take place in the core region of a star, where the temperature and pressure are high enough to sustain the nuclear reactions that power the star. The convection zone is a region of the star where heat is transported through the movement of gas, but fusion does not occur there.
Physics, chemistry and engineering i think
Take the baby to the doctor
