Solution

(a) The process represents nuclear fusion.
In this process, when two smaller nuclei of deuterium are heated to an extremely high temperature under extremely high pressure, a heavy nucleus of helium and a neutron are emitted. A tremendous amount of energy is also liberated.
(b) Particle c is a neutron and x is equal to 1.
(c) E represents the tremendous amount of energy liberated.
(d) The two conditions are given below.
(i) Millions of degrees of temperature
(ii) Millions of pascals of pressure
(e) A hydrogen bomb is based on similar reactions.
