Answer: Forensic science
In early 1800s, the professional investigators
regularly attend court trial to answer questions
related to physical evidence, which is described as forensic science. The study

Answer:
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.
