The sun is a hot plasma (ionized matter) with its inner core at a temperature exceeding  and its outer surface at a temperature of about 6000 K. At these high temperatures no substance remains in a solid or liquid phase. In what range do you expect the mass density of the sun to be ? In the range of densities of solids and liquids or gases ? Check if your guess is correct from the following data: mass of the sun  radius of the sun .  

Answer:

Mass of the sun, Radius of the sun, Volume of the sun,   Density of the sun,   . The density of the sun is in the range of the densities of the solids and liquids but not gases. The high density is due to the invard gravitational attraction on the outer layers due to the inward layers of the sun.
