Nuclear Energy II

Front

What is the nuclear process that occurs in the sun and other stars?

Back

Fusion.

Front

Describe the process that occurs when two sets of nuclei merge to form one large nucleus.

Back

Fusion, where many small nuclei combine to form one larger nucleus.

Front

What nuclear process is driven by high temperatures pushing down on nuclei?

Back

Fusion.

Front

Why is water used in a nuclear power plant?

Back

To provide a controlled nuclear reaction.

Front

What type of nuclear reaction is the hydrogen bomb?

Back

Fusion.

Front

What is the primary difference between nuclear fission and nuclear fusion?

Back

Nuclear fission splits large nuclei into smaller ones, while nuclear fusion combines small nuclei into larger ones.

Front

What conditions are necessary for nuclear fusion to occur?

Back

High temperature and pressure.

Front

What is the role of temperature in nuclear fusion?

Back

High temperatures provide the energy needed to overcome the repulsive forces between positively charged nuclei.

Front

What is a common fuel used in nuclear fusion reactions?

Back

Hydrogen isotopes, such as deuterium and tritium.

Front

What is the main advantage of nuclear fusion over nuclear fission?

Back

Fusion produces more energy and generates less radioactive waste.
