What is the average density of the sun?
The corona is much hotter than the photosphere, yet we have to wait for a total solar eclipse to see the corona. Why is that?
What are the three layers of the sun?
There are more than 3 layers to the sun starting at the core and outwards Core Radiative Zone Convective Zone Photosphere Chromosphere Corona its "atmosphere" for more information check related link
One statement about the Sun from Part A is The corona is hotter than the photosphere Which of the following statements provides observational evidence for this claim?
The corona primarily emits X rays while the photosphere primarily emits visible light
How much hotter is the solar corona than the other layers of the sun?
The hottest part of the sun is actually its center, estimated by calculations to be about 1.57E7 Kelvin.The corona is about  5E6 Kelvin.The photosphere is 5,772 Kelvin.The various layers of the sun from the center out to the photosphere decline steadily but not smoothly. Obviously there is an internal layer of the sun at the same temperature as the corona.
What is the atmosphere of the sun?
Corona the corona is the Sun's atmosphere,extending out several million miles from the Sun's visible face,the photosphere despite its extent,it is exceedingly faint,shining with only one-millionth as much light as the photosphere.For this reason the corona is most easily photographed during a solar eclipse,when the photosphere blocked by the Moon.A capful of gas from the photosphere contains a trillion times more gas particles than a cupful from the corona. Only the Sun's outer layers, collectively referred to as the solar 'atmosphere', can be observed directly. There are distinct regions to the solar atmosphere: the photosphere, the chromosphere, and the corona. These three regions have substantially different properties from each other, with regions of gradual transition between them.
Why is suns core hotter?
The corona is hotter than the photosphere because the sun's magnetic field carries energy upward from the surface and into the chromosphere and corona. The opposite effect is observed when the magnetic fields cause sunspots to form resulting in cooler surfaces.

What are the 3 sections of the sun?
There are more than three. There is the core, where the nuclear fusion takes place, the conduction and convection zones, through which the energy slowly passes, the photosphere, the chromosphere and the corona.

What is the most unknown fact about the sun?
one of the biggest puzzles is how the corona is hotter than the photosphere, when the photosphere is nearer to the core (where all the Sun's energy originates) than the corona. the solution must lie in the sun's magnetic field (as the only candidate capable of transfering so much energy), but the exact mechanism isn't understood.

What physical property of the sun is responsible for limb darkening?
The lower photosphere is hotter than the upper photosphere.
How does the density of the sun vary from the center outward?
Yes, it does. The core is much denser and hotter than, say, the chromosphere or the photosphere. A link is provided below
Why is the solar spectrum an absorption spectrum rather than an emission spectrum?
The sun has 3 layers - the photosphere, the chromosphere, the corona. Photosphere is the visible surface and gives the absorption spectrum. Chromosphere is the pinkish discharge encircling the Sun, visible only during a total eclipse. This gives the emission spectrum. Corona is the halo encircling the chromosphere. THis gives the coronal spectrum.
