NUCLEAR FISSION AND FUSSION

Front

What is nuclear fission?

Back

Nuclear fission is the process in which a heavy nucleus splits into two or more lighter nuclei, releasing a significant amount of energy.

Front

What is nuclear fusion?

Back

Nuclear fusion is the process where two light atomic nuclei combine to form a heavier nucleus, releasing energy in the process.

Front

What happens to mass during nuclear fission?

Back

The mass of the products is less than the mass of the original nucleus due to the conversion of mass into energy.

Front

What happens to mass during nuclear fusion?

Back

The mass of the products is greater than the mass of the original nuclei, as some mass is converted into energy.

Front

What is an example of a controlled fission reaction?

Back

Nuclear power plants utilize controlled fission reactions to generate electricity.

Front

What is an example of an uncontrolled fission reaction?

Back

An atomic bomb is an example of an uncontrolled fission reaction.

Front

What is the primary fuel used in nuclear fission?

Back

Uranium-235 is the primary fuel used in nuclear fission reactions.

Front

What is the primary fuel used in nuclear fusion?

Back

Hydrogen isotopes, such as deuterium and tritium, are commonly used in nuclear fusion reactions.

Front

What is the role of a moderator in a nuclear reactor?

Back

A moderator slows down neutrons to sustain a controlled fission reaction.

Front

What is the difference between nuclear fission and fusion?

Back

Fission splits heavy nuclei into lighter ones, while fusion combines light nuclei to form heavier ones.
