Interpretation:
The given terms nuclear fission, nuclear chain reaction, Critical mass should be defined.
Concept introduction:
Nuclear fission:
It is the process in which a heavy nucleolus (whose mass number greater than the 200) splits into form smaller nuclei of intermediate mass and one more neutrons.
A large atomic nuclei gets decomposed due to bombardment of some subatomic particle forming one or more than one.
Nuclear fusion: when two or more than two nuclei is joined together to form a bigger nuclei is called as nuclear fusion.
Critical mass: It is the smallest amount of fissile or fuel, material needed for a sustained nuclear chain reaction.
The critical mass of a fissionable material depends upon its nuclear properties.
Nuclear chain reaction:
It occurs when one single nuclear reaction is responsible to initiate one or more subsequient nuclear reactions.
Most of the nuclear reaction may be the fission of heavy isotopes like (uranium -235,
A nuclear chain reaction is a self-initiated sequence of nuclear reaction.
To determine: Define and explain the following termed mentioned in below.
