It's not that they have more hydrogen, but that they have more mass, which means stronger gravity which causes nuclear fusion in their cores (basically a constant chain of nuclear explosions) which converts their mass to energy which is emitted in the form of light.
The more mass, the more gravity, the more nuclear fusion, the hotter the surface temperature, which changes the light being emitted.
What else can I help you with?
Is the sun or a blue star hotter?
The blue star is hotter
Is a blue star hotter than a red giant?
blue stars are hotter
What is hotter a black star or a white star?
Technically Blue stars are hotter but from your options, white stars are hotter.
A white blue star is hotter than a red stra?
The blue star is the hottest.
Is a white-blue star is hotter than a red star?
Yes it is
Why does a star seems to be blue?
Some stars ARE blue - the hotter ones.
Suppose you see two stars a blue star and a red star what can you conclude about the two stars?
The color of a star is influenced by its temperature, with blue stars being hotter than red stars. Therefore, you could conclude that the blue star is hotter than the red star. Additionally, blue stars typically have shorter lifespans than red stars.
Why is a blue star hotter than a white star?
It's not. White is the hottest. Then blue, yellow orange, red.
What can be said with certainty about a red star and a blue star?
A red star is cooler and has a lower temperature compared to a blue star, which is hotter. Red stars are typically older, while blue stars are younger. The color of a star is determined by its surface temperature, so these differences in characteristics between red and blue stars are consistent.
temperature of blue star?
A blue star is a type of star that is hotter and brighter than other stars. It has a temperature that is much higher than other stars due to its high mass. The temperature of a blue star can range from 10,000 Kelvins to over 50,000 Kelvins. This is much higher than the average temperature of stars in the universe, which is around 5,000 Kelvins. The color of a blue star is determined by its temperature. As the temperature increases, the star appears bluer and brighter. The hottest blue stars have temperatures of up to 50,000 Kelvins, and appear to be almost white. The temperature of a blue star also affects its size and brightness. The hotter and brighter the star, the larger and brighter it is. For example, the hottest blue stars can be up to 10 times the size of a typical red dwarf star. In addition to its temperature, the surface gravity of a blue star also affects its temperature. The higher the surface gravity, the hotter the star will be. This is due to the fact that the star has to work harder to fight against the strong gravitational pull of its massive core. Finally, the composition of the star also affects its temperature. Blue stars are composed mostly of hydrogen and helium, which are the two most common elements in the universe. The more hydrogen and helium that a star contains, the hotter it will be. In summary, the temperature of a blue star is determined by several factors, including its mass, surface gravity, and composition. The hotter and brighter the star, the higher its temperature will be. The temperature of a blue star can range from 10,000 Kelvins to over 50,000 Kelvins.
