Any hot object will glow brighter when it is hotter.
Sirius appears brighter than Pollux because it is closer to Earth and is a more luminous star. Sirius is also a hot, blue star compared to Pollux, which is a cooler, orange giant star, further contributing to the difference in brightness.
Arcturus is hot. Bear in mind that only a hot star is even going to be seen in the night sky. Any cold star would also be dark.
Betelgeuse is brighter.
Yes, a star appears brighter if it is closer to Earth because the brightness of a star we see is affected by its distance. The closer a star is, the greater the amount of light that reaches Earth, making it appear brighter in the sky.
All stars are hot. A white star is hotter than average with e temperature of about 7,200 to 9,200 degrees Celsius.
They don't. Other things being equal (especially if the size and distance is the same), a hotter star will appear brighter, and in a different color.
A star that is brighter than another.

It is brighter because it is emitting more gasses at a faster rate than other sized main sequence stars.
Betelgeuse is brighter.
Because it actuall IS brighter.
Brighter Star Secondary School was created in 1993.

If the temperature is cold then the luminol will have a brighter excited state than if the temperature was hot or room temp.
