I need to find a graph about black holes temperature for a science project and this s the only one i could find ... but i dont get what it means

would someone be able to quickly expliain itto me?

thanks so much!

Answer 1

its basically showing the well known fact that the more massve the black hole, the colder it is.

Answer 2

The graph you cite is beyond me, but I do know that the larger a black hole might be the cooler it will be.

Answer 3

That graph isn't very clear.  Perhaps another graph would be better.  This website has an article and a graph at the end that also has a short caption that explains it slightly, and the graph includes information about black hole temperatures.  

I'm not sure if this next image qualifies as a graph, but it does have to do with temperature of black holes, or rather the disk around a black hole, I believe.

This next site has a graph with temperature, but it looks a little technical, but I think it has some explanation, but in technical terms.

I hope one of these graphs might be easier to understand...

Answer 4

Looks pretty clear and straightforward to me...note how "flat" each line is...each line represents a different "dimension", but ignore that for now.  Any one line shows that the temp changes little, maybe dropping a little, as the mass increases...

Exactly what the dimensions are , and how they play into the idea of holes, I don't know.

One other little point btw..."temperature" has little meaning here., or at least it should be noted that the word has a strict meaning that has more to do with atomic interactions than it has with how quickly you'll break out into a sweat.

Answer 5

I'm ignorant of the theory, myself, but Wikipedia has an article on the subject.

There's also a discussion of it at physicsforums.
