25. For the nuclear fusion reactionH+3 H Heto n temperature to which gasesmust be heated is 3.7 Ă 109 K. Potential energybetween two nuclei is closest to (Boltzmann'sconstant k 1.38 x10-23 J/K) |

Answer» Energy equivalent of temperature T is given by kT where k is the Boltzmann constant = 1.3806488 × 10^-23J/K.The energy equivalent of 3 x 10^9K is 1.3806488 × 10^-23J/K x 3 x 10^9K = 4.1419464 x 10-14J.This much energy is required to overcome the potential barrier. So the P.E. (the Coulomb barrier) |
