Does a star get brighter when is hot or cold?
Any hot object will glow brighter when it is hotter.
What are Two reasons why one star would be brighter than another?
One reason could be that the brighter star is larger and hotter, emitting more light. Another reason could be that the brighter star is located closer to Earth, making it appear brighter in the sky.
What are three physical factors that determine a star's brightness?
Three physical factors that determine a star's brightness are its temperature (hotter stars are brighter), size (larger stars are generally brighter), and distance from Earth (the closer a star is, the brighter it appears).
Is a small star brighter than a large star?
It all depends on the luminousity of the star and the relative distance of the observer.
What happens to brightness as surface temperature of the main sequence stars increase?
The hotter the star, the brighter. Ex: A stove
What are the factors that make one star appear brighter than another star?
The size of the star, because the smaller the star the hotter it is because of nuclear fusion. So the hotter the brighter.
Does a star get brighter when is hot or cold?
Any hot object will glow brighter when it is hotter.
Is Sun hotter than the star VV cephie?
You know, VV cephie is orange, sun is yellow and yellow is brighter than orange and the brighter the star is, the hotter it gets. So sun is hotter than VV cephie.
The bigger the hotter the star the what?
The bigger and hotter a star is, the shorter its lifespan will be. This is because higher temperatures cause stars to burn through their fuel more quickly, leading to a faster depletion of their energy source and a shorter overall existence.
What are Two reasons why one star would be brighter than another?
One reason could be that the brighter star is larger and hotter, emitting more light. Another reason could be that the brighter star is located closer to Earth, making it appear brighter in the sky.
Does oxygen make things burn brighter?
Oxygen is what makes things burn at all. The more oxygen there is, the brighter it can burn.
How does the HR diagram explain why some smaller cooler stars are brighter than larger hotter stars?
In terms of absolute magnitude, a larger hotter star will necessarily be more luminous than a smaller cooler star. However, if a smaller cooler star is much closer to us than a larger hotter star, it may appear to be brighter. None of this has anything to do with the HR diagram.
What are three physical factors that determine a star's brightness?
Three physical factors that determine a star's brightness are its temperature (hotter stars are brighter), size (larger stars are generally brighter), and distance from Earth (the closer a star is, the brighter it appears).
Why do stars with smaller masses burn longer than stars with larger masses?
Stars with larger masses have stronger gravity; this results in more pressure; which in turn makes the star hotter. As a result of the higher temperature, they will shine brighter, and burn their fuel much faster.
Is a small star brighter than a large star?
It all depends on the luminousity of the star and the relative distance of the observer.
What happens to brightness as surface temperature of the main sequence stars increase?
The hotter the star, the brighter. Ex: A stove
Will a super red giant live longer than a red giant star and which will burn hotter?
A supergiant is brighter than a red giant. That means it spends its energy faster, and lives less. To burn its energy faster, it must be hotter in its nucleus. That doesn't necessarily mean that its surface temperature is faster (rather, it will usually be bigger, and have a larger surface to irradiate).
