Question
Differentiate between nuclear fission and nuclear fusion.
✓
Answer
|
|
Nuclear Fission
|
Nuclear Fusion
|
|
Natural occurrence of the Process:
|
Fission reaction does not normally occur in nature.
|
Fusion occurs in stars, such as the sun.
|
|
By products of the reaction:
|
Fission produces many highly radioactive particles.
|
Few radioactive particles are produced by fussion reaction, but if a fission "trigger" is used, radioactive particle will result from that.
|
|
Energy ratios:
|
The energy released by fission is a million times greater than that realeased in chemical reaction; but lower than the energy released by nuclear fusion.
|
The energy released by fusion is three to four times greater than the energy released by fission.
|
|
Nuclear weapon:
|
One class of nuclear weapon is a fission bomb, also known as an atomic bomb or atom bomb.
|
One class of nuclear weapon is the hydrogen bomb, which uses a fission reaction to "trigger" a fusion reaction.
|
|
Energy requirement:
|
Takes little energy to split two atoms in a fission reaction.
|
Extremely high energy is required to bring two or more protons close enough that nuclear forces overcome their electrostatics repulsio.

When a person puts food in his mouth, then teeth cut it into small pieces, chew and grind it. The glands A in the mouth secrete a substance B which is mixed with the food by tongue. The substance B contains an enzyme C which starts the digestion of food in the mouth. The slightly digested food from the mouth goes down a tube D. The special type of movements E in the walls of tube D push the food into stomach for further digestion. The stomach wall secretes gastric juice containing three substance F, G and H. One of the functions of F is to kill bacteria which may enter the stomach with food. The substance G protects the inside layer of stomach from the damaging effect of substance F whereas substance H is and enzyme for digestion. The partially digested food then enters into small intestine for further digestion.
