The core of the sun is group of answer choices

1. at the same temperature but much denser than its surface.
2. much hotter and much denser than its surface.
3. composed of iron. constantly rising to the surface through convection.
4. at the same temperature and density as its surface.

2. much hotter and much denser than its surface

Explanation:

We know that the temperature around the center of the Sun is about 1.57×10⁷ K and its density is about 162 g/cm³.

Now, the temperature and the density decrease as one moves outward from the center of the Sun, the temperature at the surface of the sun is about 5×10³ K and the density as an average in the surface is about 1.4 g/cm³.

Therefore the answer is:

2. much hotter and much denser than its surface.  

I hope it helps you!

Have a nice day!
