Compare fission and fusion reactions and explain the difference between their energy input and output.

Answer :

Nuclear fusion : It is defined as a process which involves the conversion of two small nuclei to form a heavy nuclei and some amount of energy is also releases.

Nuclear fission : It is defined as a process which involves the conversion of a heavier nuclei (which is an unstable nuclei) into two or more small nuclei (which is a stable nuclei) and a large amount of energy is also releases.

The difference between the nuclear fusion and nuclear fission is that, the energy is given in the nuclear fusion reaction but the energy is releases in the nuclear fission reaction.

In nuclear fusion, a small amount of energy is released but in nuclear fission, more amount of energy is released.

lol for the pointsss
