The simplest way we can determine the surface temperature of a star is by its?

Question

A. brightness.
B. spectrum.
C. color.
D. mass.

Answer 1

Are these test questions being asked by the same person or several different people from the same class? And do you know that there is a separate astronomy section where these questions would fit better?

Answer 2

Color

Answer 3

the sunlight floor temperature is approximately 10000 F. There are storms (Sunspots) indoors the exterior that are approximately 7000 F. the quantity of Sunspots has a cycle of 11 years. each 11 years this form of Sunspots will strengthen so the temperature decreases. a transformation of 0.05 tiers won't make any huge distinction. the sunlight's temperature and the cycle of Sunspots are consequence of no planet.

Answer 4

Definitely color and here is why I believe that is so:

A white dwarf star is young, and still very hot. Later that white dwarf will grow into a larger yellow star - cooler, but still hot, like our star.

As the fuel inside the star is spent, it loses it's gravitational pull, so it's surface gets farther and farther away as it cools - giant stars are red - red giants. They are older, much of their fuel is gone, and they have less gravitational pull.
