Nuclear Fusion Review

Front

What is the process of nuclear fusion?

Back

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

What element is primarily fused in the Sun to produce energy?

Back

Hydrogen is primarily fused in the Sun to produce energy.

Front

What new element is created when hydrogen is fused together on the Sun?

Back

Helium is created when hydrogen is fused together on the Sun.

Front

Do all stars generate energy through nuclear fusion?

Back

Yes, all stars generate energy through nuclear fusion.

Front

What happens to energy during the process of nuclear fusion?

Back

Nuclear fusion releases energy.

Front

What initiates the birth of a star?

Back

A star is born when nuclear fusion starts.

Front

What is a supergiant star?

Back

A supergiant star is a very large star that is more massive than a giant star and has expanded and cooled after the main sequence phase.

Front

What is the main sequence phase of a star?

Back

The main sequence phase is the period in a star's life when it is fusing hydrogen into helium in its core.

Front

What are the conditions necessary for nuclear fusion to occur in stars?

Back

High temperature and high pressure are necessary for nuclear fusion to occur in stars.

Front

What is the significance of nuclear fusion in the universe?

Back

Nuclear fusion is significant because it is the process that powers stars and produces the elements necessary for life.
