Question

Fusion processes, like combining two deuterons to form a `He` nucleus are impossible at ordinary temperature and pressure. The reasons for this can be traced to the fact:
A. nuclear forces have short range
B. nuclei are positively charged
C. the original nuclei must be completely ionized before fusion can take place
D. the original nuclei must first break up before combining with each other

Answer 1

Correct Answer - a,b
Fusion processes are impossible at ordinary temperature and pressures. The reason is nuclei are positively charged and nuclear foreces are short range strongest forces.
