Temperature of the big bang explosion?

Answer 1

It's white hot; the thermal pulse from a nuclear weapon is briefly as hot as the surface of the sun, 6000 degrees Kelvin. Most of the damage from a nuclear weapon is produced by heat from this radiant pulse moving outward at the speed of light. Like the sun, the energy from the nuclear radiant pulse is mostly visible and near-infrared (NIR) radiation, shifting slightly to shorter wavelength with increasing weapon yield, as illustrated in Figure 1. The duration of the radiant pulse increases proportionately with the yield of the nuclear weapon. Typical durations of radiant pulses

Answer 2

There is no upper limit, when fission occurs the fissioning material will just go on getting hotter, and eventually it would melt or vaporise, so that the shape would probably then change and make the assembly sub-critical. In a nuclear reactor producing substantial power it is essential to cool the fuel to keep it within material constraints, but if the cooling failed completely and the reactor continued at power the fuel would melt. This must always be prevented by engineered safeguards.

Answer 3

During the Big Bang, there was an infinite amount of energy present, with infinite temperature. It was so hot, the four forces, Gravity, Electromagnetism, Strong nuclear and weak nuclear all were unified. As the universe cooled, Gravity, an attractive force present with all matter with mass, broke off, then The Strong nuclear, the force that holds the nucleus' of atoms together and the strongest of the forces broke off. The weak nuclear, the force that institutes radioactive decay of atoms broke off, leaving electromagnetism which separated into to connected forces, electricity and magnetism.

Answer 4

This seems poorly defined to me, however, the temperature must the temperature of the driving reaction. example if solid, frozen nitrogen was heated in a sealed container the "explosion" would have the temperature of boiling liquid nitrogen. If the "explosion" was methane and oxygen fire, then in would have the temp. of burning methane, et. ect.

Answer 5

The explosion of the Atomic bomb on Hiroshima was three times hotter than the surface of the sun!!

Answer 6

The amount of heat produced is directly proportional to its explosive yield.

Answer 7

Couple million degrees.

Answer 8

10^6 K (Kelvin)
