Fission vs Fusion

Front

What is nuclear fission?

Back

Nuclear fission is a nuclear reaction in which the nucleus of an atom splits into two or more smaller nuclei, along with the release of energy.

Front

What is nuclear fusion?

Back

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

Front

How do nuclear power plants generate energy?

Back

Nuclear power plants generate energy through the process of fission, where the splitting of atomic nuclei releases heat, which is used to produce steam that drives turbines.

Front

What happens to the mass during nuclear fission?

Back

During nuclear fission, 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 the mass during nuclear fusion?

Back

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

Front

What is a common example of nuclear fission?

Back

A common example of nuclear fission is the reaction that occurs in nuclear reactors, such as the fission of Uranium-235.

Front

What is a common example of nuclear fusion?

Back

A common example of nuclear fusion is the process that powers the sun, where hydrogen nuclei fuse to form helium.

Front

What is the role of neutrons in nuclear fission?

Back

Neutrons initiate the fission process by colliding with the nucleus of an atom, causing it to become unstable and split.

Front

What is the role of temperature in nuclear fusion?

Back

High temperatures are required for nuclear fusion to occur, as they provide the energy needed to overcome the repulsive forces between positively charged nuclei.

Front

What is half-life in the context of nuclear reactions?

Back

Half-life is the time required for half of the radioactive nuclei in a sample to decay, which is relevant in both fission and fusion processes.
