I dont mean only somethings I mean all things. For example a lightbulb.

Answer 1

You might be confusing this with the temperature of a "black body" as a function of the frequency of the blackbody radiation. The higher the frequency, the hotter the source. That's why blue stars are hotter than white stars (like our sun), and white stars are hotter than red stars. Luminosity, which is what you're saying about "brightness", doesn't indicate temperature. As an example, a welder using an arc welder emits a blue light, but may not as bright as the overhead incandescent lights that's illuminating his work. But it's the arc weld that's a lot hotter than the bulb filament.

Answer 2

No, not necessarily. For example, LED lights can be very bright but emit next to no heat. More energy efficient light bulbs are always being developed that are just as bright as any other but emit less heat, thus conserving energy.

Answer 3

If you look at it when metal is heated it becomes red hot,bit when it gets even hotter it becomes white. Along the same vein is the fact that an acetylene torch is red when lit,but becomes white when oxygen is added. I may be wrong but all this sounds logical.

Answer 4

in science I believe it mostly is based on color. ie. white is hotter than yellow, yellow is hotter than red and so on. brightness testifies to the amount of energy something emits

Answer 5

No When my wife bends over the sun shines and she is just as hot

Answer 6

Yes--I am Sunshine,and equally bright;)

Answer 7

MORE BRIGHTER AND MORE HOTTER. LEARN PROPER GRAMMER BEFORE POSTING QUESTIONS.

Answer 8

no
