The surface temperature is not a reliable indicator about how long a star will last. However, the total energy output is. If a star produces a lot of energy, it will burn through its fuel faster.

Are all-stars the same as the sun?
No, some are hotter/cooler, some are more/less massive, but they all follow the same life processes.
Do hot stars or cold stars live longer?
There is no such thing as a cold star, as even the lowest-temperature stars are very hot. That said, cooler stars last longer as they burn their fuel more slowly.
How did the sun get its color?
The sun's color results from the temperature of its outer layer, which emits light in the yellow part of the visible spectrum. Hotter stars tend to emit more light in the blue part of the spectrum while cooler stars are more reddish.
What is the relationship between the color and the temperature of star?
The relationship is that the color is an indication of the star's surface temperature. For example, red stars are cooler, while blue stars are hotter. You can find more details in the Wikipedia article "Stellar classification".
Hotter stars glow with light that is more intense at?
Hotter stars flow with light that is more intense at shorter wave lengths. The hottest stars emit their radiation in short violet light wavelengths. Their light appears blue white when observed.
Do dimmer stars live longer lives?
Dimmer stars generally are just farther away. Their brightness isn't necessarily a factor in how long they live. Their color is actually a better indicator. Yellow stars, like our own sun, burn cooler, and are therefore using their fuel more slowly. This will cause them to live longer. Stars with a red color are burning much hotter, and will therefore use up their fuel more quickly. Blue or white colored stars are burning hotter still!
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.
What does color indicate in stars?
How hot or cool a star is. For example if a star is red, it's cooler. If a star is more blue, it's hotter.
Are all-stars the same as the sun?
No, some are hotter/cooler, some are more/less massive, but they all follow the same life processes.
Do hot stars evolve more slowly than cool stars?
Hot stars are more massive than cooler stars and thus use up their available fuel much more quickly.
Does cooler magama flow more or less quickly than hotter magma?
Cooler magma flows slower than hotter magma.
Do hot stars or cold stars live longer?
There is no such thing as a cold star, as even the lowest-temperature stars are very hot. That said, cooler stars last longer as they burn their fuel more slowly.
Does cooler magma flow more or less than hotter magma?
when magma is melted at a higher temp. it'll be more runny so cooler magma will be slower than hotter magma
How did the sun get its color?
The sun's color results from the temperature of its outer layer, which emits light in the yellow part of the visible spectrum. Hotter stars tend to emit more light in the blue part of the spectrum while cooler stars are more reddish.
How is a star measured by color?
Blue stars are hotter than the sun, white ones about the same, and red ones are cooler. If you use a spectroscope the calculations are much more precise.
Does cooler magma flows more or less quickly than hotter magma?
when magma is melted at a higher temp. it'll be more runny so cooler magma will be slower than hotter magma
The color of the star can be indication of the?
The star's temperature. The more blue the star is the hotter it is. Pure blue stars get up to around 18,000 k. The more red the star is the cooler it is. Pure red stars can get up to around 2,500 k. White, yellowish color stars are in the middle.
