About 1 μs after the Big Bang, the temperature of the universe was about 10¹³ K. What energy (in eV) does this correspond to? A)1 neV B)1 keV C)1 MeV D)1 GeV E)1 TeV

Question

Quizplus · Accepted Answer

The energy corresponding to a temperature can be calculated using the formula E = kT, where k is the Boltzmann constant (8.617 x 10^-5 eV/K). For a temperature of 10^13 K, this gives an energy of approximately 1 GeV.
