Interpretation Introduction

Interpretation:

The process that is involved in generation of energy in sun has to be chosen from the given options.

Concept Introduction:

Nuclear reactions can be further classified into two additional types.  They are nuclear fusion reaction and nuclear fission reaction.  These are used as source of energy.

Nuclear fission reaction is the one in which a large nucleus gets split up into two medium-sized nuclei with more free neutrons and a huge amount of energy.  The word “fission” itself mean that it is splitting.

Nuclear fusion reactions are the one in which a large nucleus is formed from two small nucleus with release of huge amount of energy.  For a nuclear fusion reaction to occur a very high temperature is required.
