blue is hotter than red and yellow but yellow is hotter than red.
A stars color is determined mainly by it's surface temperature. They tend to range from Blue (hottest) thru white and yellow to red (coolest). One thing to bear in mind tho is that a Red Giant star, for example, produces more heat than a smaller yellow star but because the star is much bigger the heat is more spread out (because the surface area is so much bigger) and therefore it appears red.
No, a yellow flame is colder than a blue flame.
yes
About a quarter of all stars are bigger than the sun, some of them a lot bigger.
yes. size is proportionate to color. as stars cool, they expand. a blue star thus cools into a yellow star while simultaneously expanding
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.
It's not. White is the hottest. Then blue, yellow orange, red.
Depends what type of dwarf star. - Our Sun is a yellow dwarf.

A star's color tell us how old the star is and how hot the star is. A blue star is very hot and is young, a yellow star is cooler than blue, but hotter than red and is about half way through its lifetime, lastly a red start is cooler than yellow and blue and is near the end of it's life. submitted by: Fabrigar, Lovely Joana Ymas.
There are two types of star that can be red. Red dwarfs are smaller than the sun. Red giants are far larger than the sun.
Many stars are bigger than the sun. In fact the sun is called a yellow dwarf, or a G dwarf star meaning it is relatively small (i.e. a dwarf) compared to the "average star" in our galaxy.
Yellow and sticky and a little bigger than jelly beans :)
a blue whale is bigger than a eel.
The bird you are referring to is a Grackle. The female has the yellow eyes.
