A red giant star.
When a star changes from blue to red what happens to the surface temperature?
The temperature is lowered.
Color of star with temperature of 3000 Celsius?
red
When does a red star become a red giant?
A star become a red giant when the core contracts, the temperature increases and the outer layers of the star begin to expand. By the end of this phase, the star can be 10 to 100 times it diameter. When the temperature in the core reaches 100 000 000°C, the helium start fusing into carbon. Because the star has expanded to such an enormous size, that the outer layer are much cooler than when the star was a main sequence star. It therefore appears red, earning the name of red giant.

Are red stars old or new?
The color of a star does not directly determine its age. Red stars are large and a little less hot then the Sun. Scientists can use the color of a star to determine its heat and then using that and its mass determine how old it is.
How do blue star differ from the red star?
they are differ by their color they are also differ in temperature
Suppose you see two stars a blue star and a red star what can you conclude about the two stars?
the blue star has a hotter surface temperature than the red star. (:
