Question 1

Nuclear energy

Answer 1

Atomic energy, released during nuclear reactions such as radioactive
decay, nuclear fission and nuclear fusion

Question 2

Nuclear fission

Answer 2

Nuclear reaction when a heavy nucleus splits into two or more lighter
nuclei while releasing a large amount of energy

Question 3

Nuclear fusion

Answer 3

Nuclear reaction in which small and light nuclei fuse to form a heaview
nucleus while releasing a large amount of energy. This nuclear reaction
happens under extremely high temperature and pressure

Question 4
