What is the relation of the colors and temperature of the stars to their life span?

The color of a star tells you which kind it is. It also tells you how hot the star is burning. And the hotter the star the more fuel it would use up and that tells you the life span of the star.

Is it true that the length of a stars life depends mainly on its temperature?
Yes (and its temperature depends on its size), the bigger (and hotter) the shorter its life.
How are betelgeuse and pollux stars alike?
Both Betelgeuse and Pollux are close to the end of their life. Both of the stars are large and cold in surface temperature. One difference is that Betelgeuse is a red supergiant, and Pollux is an orange giant.
Why stars are different?
At first glance, the stars may appear to all be white, but if you look at them from dark skies for any amount of time, you will see they are a diverse variety of colors,red,yellow, white, and blue. Why should this be? Why should the stars come in so many colors? Why not just white? It turns out the answer is because they are hot. All matter emits radiation, peaking at a wavelength (which can sometimes be seen as a color) which is dependent solely on the temperature of the body. This is known as Wein's law (pronounced Veen's law). Most objects we encounter in everyday life are somewhere around room temperature. Give or take a few thousand degrees. This effect, known as blackbody radiation, happens to all objects, regardless of it's temperature. Objects which have a surface temperature just a few degrees above absolute zero (which is -273 c.) radiate most of their radiation in the form of radio waves. Hotter than that, and the object glows in microwaves. After that, it radiates largely in the form of infrared waves. Hotter still, and the object glows red, then orange, yellow, green, then blue. This is the reason metal glows when it is hot. When the temperature is hot enough to have the atoms or molecules moving at wildly different speeds at the surface, all at around room temperature, the object will be seen to glow white hot, as white light is made from a composite of all the visible colors. When an object reaches a temperature where it becomes too hot to radiate black body radiation in the visible wavelengths, it will shine in ultraviolet wavelengths. Hotter still, x-rays, and finally gamma rays. Why does this happen? Because as an object grows hotter, there is, logically, more energy being released. As the energy level of radiation is increased, the wavelength becomes shorter and shorter. When the human eye perceives different wavelengths of visible light, we interpret it as different colors. This is why a rainbow always appears with the same colors in the same order. Red, orange, yellow, green, blue, indigo, and violet. You will never see a rainbow with any other colors, or with the colors in any other order. The coolest stars are around 3,000 degrees c. They are the red stars. Stars like the sun are next, glowing at about 6,000 degrees c., and are, of course, orange/yellow (although as we discussed last week, the Sun is greener than you think). 10,000 degrees c. will buy you a green star, and the going price on a blue star is around 25,000 degrees c. There are cool stars which radiate in the infrared, and will last dozens of billions of years. There are stars which expend their energy in the ultraviolet, and will last only a fraction of the lifetime of the Sun. Many of these stars cannot be seen with the naked human eye.
What type of stars end their life as a supernova?
Massive Stars.
What type of stars end their life in supernovae?
Massive Stars.
What is the relation between a stars mass and expected life?
star are not as heavy as us.{might not be correct}
Is it true that the length of a stars life depends mainly on its temperature?
Yes (and its temperature depends on its size), the bigger (and hotter) the shorter its life.
How are stars different colors?
At different stages in their life cycles they have different temperatures and radiate different visible wavelengths.
Is the smallest star larger than any planet?
Some stars can be smaller than planets. Stars exist in a variety of colors, shapes, sizes, stages of "life", and types.
How does the color of a star indicates the chemical?
Different colors of stars can tells us the temperature of that star. It can also tell us the luminosity and mass of a star and where it is in its life cycle, whether it is a proto-star (new) or red super giant (dying high mass stars), or white dwarf (dying low mass stars).

When was Colors in My Life created?
Colors in My Life was created in 2002.
What has the author Charles L McKenney written?

What is relation between mathematics and environment?
the relation is that both helps in our daily life
Why is a star white?
stars are not always white there are many different types of star for example: Black Dwarf Red Giant White Dwarf Blue Giant Neutron they are all varying colors because of the configurations of gas and energy of particals. however 97% of our galaxy's stars are the fabled white dwarf these are white because they are expelling there entire energy at once, the white dwarf is the final stage of a stars life, aside from the purely theoretical black dwarf
What is relation between Fahrenheit and temperature?
Fahrenheit is a unit to measure temperature. It is an old-fashioned unit, hardly used any longer (with the notable exception of the United States); the units that are usually used for temperature are Kelvin (in the scientific community) and Celsius, also known as Centigrade (in everyday life).
Do stars have life?
No; stars are not, to the best of our knowledge, "alive".
