Question
Deuterium (2H), when heated to sufficiently high temperature, undergoes a nuclear fusion reaction that results in the
production of helium. The reaction proceeds rapidly at a
temperature, T, at which the average kinetic energy of the
deuterium atoms is 8 × 10-16 J. (At this temperature, deuterium molecules dissociate completely into deuterium
atoms.)
(a) Calculate T in kelvins (
(b) For the fusion reaction to occur with ordinary H
atoms, the average energy of the atoms must be about
32 × 10-16 J. By what factor does the average speed
of the 1H atoms differ from that of the 2H atoms of
part (a)?
