The Total solution for NCERT class 6-12
The Sun is a hot plasma (ionized matter) with its inner core at atemperature exceeding 107┬аK, and its outer surface at atemperature of about 6000 K. At these high temperatures, no substance remainsin a solid or liquid phase. In what range do you expect the mass density of theSun to be, in the range of densities of solids and liquids or gases? Check ifyour guess is correct from the following data: mass of the Sun = 2.0┬а├Ч┬а1030┬аkg, radiusof the Sun = 7.0┬а├Ч┬а108┬аm.
Mass of the Sun,┬аM┬а= 2.0 ├Ч 1030┬аkg
Radius of the Sun,┬аR┬а= 7.0 ├Ч 108┬аm
The density of the Sun is in the density range of solids andliquids. This high density is attributed to the intense gravitationalattraction of the inner layers on the outer layer of the Sun.
