Front

What is the largest element that any star can create?

Back

Iron

Front

What happens during a supernova explosion of a super giant?

Back

It lasts only a few seconds and hydrogen, helium, and other fused elements are ejected.

Front

What conditions are required for the process of fusion to occur?

Back

High heat and high pressure.

Front

What are main sequence stars?

Back

They are the majority of stars in the universe and are in the stage when the star fuses Hydrogen into Helium.

Front

What does the Sun produce energy by fusing hydrogen atoms into?

Back

Helium.

Front

What is a supernova?

Back

A supernova is a powerful and luminous explosion of a star.

Front

What is the process of fusion?

Back

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

Front

What elements are primarily involved in the fusion process in stars?

Back

Hydrogen and Helium.

Front

What is the life cycle of a star?

Back

The life cycle of a star includes stages such as nebula, main sequence, red giant, supernova, and neutron star or black hole.

Front

What is a red giant?

Back

A red giant is a late stage in the life cycle of a star where it expands and cools after exhausting its hydrogen fuel.
