Black, It goes With everything.
It's not. White is the hottest. Then blue, yellow orange, red.
yes
The blue star is the hottest.
A red star can be more luminous than a bluish-white star if it is larger in size and/or hotter in temperature. The luminosity of a star is determined by its size and temperature, with larger and hotter stars emitting more energy. Therefore, a red star that is larger and hotter than a bluish-white star can be more luminous.
A black cup will get hotter in the sun compared to a white cup. This is because black objects absorb more light and heat than white objects, which reflect more light. The absorbed heat will cause the black cup to warm up faster.
Black asphalt becomes hotter than a white cement sidewalk by one thing. The reason it gets hotter is because black attracts heat.
A white dwarf is what remains of a star's interior, which is much hotter than the surface because it is closer to the source of fusion.
Sun
A white star is hotter than a yellow star primarily due to its surface temperature. The color of a star indicates its temperature, with blue and white stars being hotter than yellow, orange, or red stars. White stars typically have surface temperatures ranging from about 7,500 to 10,000 Kelvin, while yellow stars, like our Sun, have temperatures around 5,500 to 6,000 Kelvin. This difference in temperature is a result of the star's mass, age, and stage in the stellar lifecycle.
