How will a pulsating star appear when it is expanding?
Cooler and Dimmer
What color of the star is hottest?
the color of the hottest star is blue
Does a color of a star changes color as it gets older?
Technically no, the (visible) color of stars depends on the temperature of the star. The hotter the star, the whiter, the cooler, the redder it looks. An average star would appear pure white (Well blue actually) to a human but temperature technically changes with age as stars evolve. Eventually when a star runs out of hydrogen fuel and burns heavier elements, the outside cools to a deep red (Red giants). Young stellar remnants would also appear pure white and darker as they age until they've cooled enough to no longer emit visible EM radiation, at which point would appear the deepest black you could imagine.
What color will a star be with a surface temperature of 5000-6000K?
It will be a class "G" star with a conventional colour of yellow with an apparent colour of yellowish-white.
What makes some stars appear brighter than others the temperature or the size?
It is a mixture of both. A hotter star will generally appear brighter than a cooler star of the same size. Similarly, a large star will appear brighter than a small one of the same temperature. The brightest stars are generally red supergiants, which are comparatively cool stars, but are so large that their size more than makes up for it. A star's apparent brightness from any given vantage point also depends on its distance. The closer a star is to you, the brighter it will appear.

How does the HR diagram explain why some smaller cooler stars are brighter than larger hotter stars?
In terms of absolute magnitude, a larger hotter star will necessarily be more luminous than a smaller cooler star. However, if a smaller cooler star is much closer to us than a larger hotter star, it may appear to be brighter. None of this has anything to do with the HR diagram.
Why do sunspots appear?
Sunspots appear because of the magnetic fields, they appear black because they're slightly cooler than the surface of the rest of star.
What color of the star is hottest?
the color of the hottest star is blue
Would Star Wars beat halo?
yes, because Star Wars is way awesomer and has cooler and more powerful characters.

How far would you have to move before the constellations would appear to change shape?
To the nearest Star
Are stars cooler than the sun brighter or dimmer?
a sun is a star so it would be considered both dimmer .
Is meta cooler stronger than frieza?
Yes, Meta Cooler is much stronger than Cooler. Cooler in his 5th form was defeated by SSJ Goku; however, Meta Cooler was defeated only by SSJ Goku and SSJ Vegeta at full power.
Why does the expansion of a star's envelope make it cooler and more luminous?
The star's expansion is caused by an increase in energy. Therefore, the star becomes more luminous and cooler due to production of more energy.
