Nuclear fusion requires extremely high temperature and great pressure.
A thermonuclear burst occurs under conditions of extremely high temperature and pressure, causing the fusion of atomic nuclei and resulting in a powerful release of energy.
Very high pressure at the centre due to gravity, and high temperature. Note however that temperature does not have to be so high as in tokamaks on earth, because the pressure and hence density of the plasma is so great.
It does not have any particular temperature, the nuclear reactions are not influenced by temperature, though the behaviour of a nuclear reactor does depend on its temperature since this influences the neutron spectrum. In a PWR the coolant exit temperature is about 325 degC.
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).
A body temperature of 123 degrees Fahrenheit is extremely high and would likely be fatal. This level of temperature is well beyond what the human body can withstand and is not compatible with life. If someone were to have a temperature this high, immediate medical attention would be required.
Nuclear fusion requires extremely high temperature and great pressure.
Not nuclear, it takes an extremely hight temperature for Fusion to occur with in the sun or any other star. ADDED: Yes "nuclear". Fusion is one of the two type of nuclear reaction, the other being Fission.
The core of the protostar reached an extremely high temperature

When two nuclei of light elements are forced together at extremely high temperature, they can undergo nuclear fusion, releasing a large amount of energy in the process. This is the same process that powers the sun and other stars.
No. It takes a combination of pressure and temperature to liquefy some gases. Hydrogen and helium were the last gases to be liquefied and that was with pressure and extremely low temperature.
Compared to Earth's, it has:* A high pressure * An extremely high temperature
In areas of high temperature and high pressure
A thermonuclear burst occurs under conditions of extremely high temperature and pressure, causing the fusion of atomic nuclei and resulting in a powerful release of energy.
The high temperature plastics can only be used from the temperature of 135 degree Celsius and lower. Many others thought that high temperature plastics meant that it can handle extremely high temperature but they are wrong.
Extremely high! Take her to emergency ASAP!
Yes, it has been proven and tested that cockroaches will survive. Their resistances to radiation are extremely high, and that's one of the reasons they survived when the dinosaurs didn't.
