What is the outcome for a star with a mass greater than 20 solar masses at the end of its life cycle?.
- A.It becomes a white dwarf.
- B.It becomes a neutron star.
- C.It undergoes a supernova explosion.
- D.It becomes a red giant.
Model answer
What a good answer should say
- It undergoes a supernova explosion.
Explanation
Why this works
A star with a mass greater than 20 solar masses typically ends its life cycle by undergoing a supernova explosion. This is a key difference from less massive stars, which may end as white dwarfs or neutron stars.
This outcome applies specifically to massive stars due to their ability to fuse heavier elements until iron is formed, leading to gravitational collapse and subsequent explosion.
