Answer to Question 1

TRUE

Answer to Question 2

It is so hot that almost all the energy it gives off, by Wien's Law, is not going to be in the visible, but the X-ray portion of the spectrum. Also, it is very low density, so there are far more atoms at 5,800 K giving off a lot of visible light than the few out in the corona.
