Question

Fusion processes, like combining two deutrons ot form a He nucleus are impossible at ordinary temperatures and pressure. The resons 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. This is because nuclei are positively charged and nuclear forces are the strongest forces having short range. Choice (a) and (b) is correct.
