No, yellow is hotter. The progression, from least hot to hottest, goes: black-red, dark red, bright red, light red, orange, yellow, blue, white-yellow, white.
Rigel is hotter by a long way with a temperature of 11,000 Kelvin, whereas Betelgeuse is a cool 3,500 Kelvin
The sun is hotter than red stars but cooler than blue stars,
Different colors of lava depends on its temperature, it starts out bright orange (1000-1150 C) then it cools the color changes to bright red (800-1000 C), then do dark red (650-800 C) and then the color is brownish red (500-650 C). The solid colored lava is black (but can still be very hot).
There is no volcano that produces white lava naturally. Lava typically appears red, orange, or black due to the presence of various mineral impurities and the melting of rocks. However, artificial conditions can be created in laboratories to produce white lava as part of scientific experiments.
Its colour. White stars are hotter than blue stars which are hotter than yellow which are hotter than orange, which are hotter than red.
Red giants are not hotter than white dwarfs. While red giants are much larger and burn more fuel, white dwarfs burn at a higher temperature.
Yes it is
No, yellow is hotter. The progression, from least hot to hottest, goes: black-red, dark red, bright red, light red, orange, yellow, blue, white-yellow, white.
White Dwarves and Blue giants are both hotter than Red giant stars.
blue and white stars are hotter than red stars (and newer).
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.)
The blue star is the hottest.
It's not. White is the hottest. Then blue, yellow orange, red.
no the red jiant is hotter
No. Color, for stars, is (almost) entirely dependent on "surface" temperature, and white stars are significantly hotter then red ones. (The order from coolest to hottest goes brown, red, orange, yellow, yellow-white, white, blue-white, blue).
