Question

answer each question. think about what you learned.

1. what type of star will the sun become after it leaves the main sequence?

a neuron star
b red dwarf
c red giant
d red supergiant

1. what is the main factor that determines the stages a star will follow after the main sequence?

a mass
b brightness
c temperature
d radius

1. the sun will spend most of its life in what stage?

a red giant
b main sequence
c red dwarf
d white dwarf

1. compared to when it joins the main sequence, a star’s m (cut off) the end of its life will:

a be greater
b be the same
c be less
d depend on the type of star
how does the life cycle of a star with less mass compare with more mass? (cut off)

Explanation:

Question 1

The Sun has a mass that leads it to expand into a red giant after the main sequence. Neutron stars form from more massive stars, red dwarfs are low - mass stars that don't become giants, and red supergiants are for very massive stars. So the Sun becomes a red giant.

A star's mass is the primary factor determining its post - main - sequence stages. Brightness, temperature, and radius are related to mass or are consequences of evolutionary stages, not the main determining factor.

Stars, including the Sun, spend the majority of their lives in the main sequence stage, where hydrogen fusion occurs in the core. The red giant stage is later, red dwarfs are different low - mass stars, and the white dwarf stage is the final stage for low - mass stars like the Sun but is not the longest - lived stage.

Answer:

C. red giant
