Nuclear Fission and Fusion Practice

Front

What is nuclear fission?

Back

Nuclear fission is the process in which a large nucleus splits into smaller nuclei, releasing a significant amount of energy.

Front

What is nuclear fusion?

Back

Nuclear fusion is the process where two small nuclei collide and combine to form a larger nucleus, releasing a large amount of energy.

Front

What is a major drawback of fission power?

Back

The major drawback of fission power is the production of radioactive waste.

Front

True or False: The total mass of atoms decreases during the fission process.

Back

True. During fission, some mass is converted into energy, resulting in a decrease in total mass.

Front

What is radioactive waste?

Back

Radioactive waste is the byproduct of nuclear reactions, particularly from fission, that remains radioactive and poses disposal challenges.

Front

What is the difference between fission and fusion?

Back

Fission involves splitting a large nucleus, while fusion involves combining small nuclei.

Front

What is an example of a fission reaction?

Back

An example of a fission reaction is the splitting of uranium-235 when it absorbs a neutron.

Front

What is an example of a fusion reaction?

Back

An example of a fusion reaction is the process that powers the sun, where hydrogen nuclei combine to form helium.

Front

What is the role of neutrons in fission?

Back

Neutrons initiate the fission process by colliding with a nucleus, causing it to split.

Front

What is the energy release in fission and fusion?

Back

Both fission and fusion release large amounts of energy, but fusion typically releases more energy than fission.
