The sun is hotter than red stars but cooler than blue stars,
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.
The mantle is hotter than the crust.
The hottest stars are white or blue, cooler stars are yellowish. Cooler still are the orange stars. The coolest stars appear red. That's how the spectrum of a star is related to its surface temperature. The reason is that the hotter the star, the shorter the wavelength at which the light is most intense in its spectrum. Blue light is of shorter wavelength than red.
I expect for the mantle to be cooler
No, the core is hotter.
No, blue stars are hotter than red stars. In other words, red stars are cooler. Think of it as fire. The red one is hot, but the blue flame is RAGING hot.
No. Red stars emit less energy so they are cooler than hotter blue stars.
Red stars are cooler than blue stars
Its colour. White stars are hotter than blue stars which are hotter than yellow which are hotter than orange, which are hotter than red.
Blue Star- blue stars the super giants of the sky. they are much larger than yellow stars (about 3 times bigger) and hotter. Yellow Stars- yellow stars are a lot smaller and cooler an example is our sun. Therefore, because blue stars are hotter than yellow- they burn their nuclear fuel a lot faster and live for a shorter time.
blue stars are hotter
White Dwarves and Blue giants are both hotter than Red giant stars.
False. Blue giants(or hypergiants) are hotter than Red giant stars. White dwarves are also hotter but they are smaller than blue giants. (As is implied by the name.)
Blue or purple stars are hotter than the whites
No. Blue stars are the hottest stars, far hotter than any planet.
According to Wien's law, red stars are cooler than blue stars. This concept can be easier to understand using a light bulb. For example, when you turn off a light, the temperature of the bulb will decrease and you will notice the bulb turning red. The cooler light becomes, you will notice the obvious change in brightness and the color shifts towards red and the intensity is lowered.
No. Yellow stars are hotter than red stars.See related question.
