Question

In what range do you expect the density of the Sun to be, in the range of densities of solids and liquids or gases? Briefly explain with the help of the following data : mass of the Sun = $2.0\times {10}^{30}kg$, radius of the Sun $=7.0\times {10}^{8}m$

Answer 1

$Density=\frac{massofsun}{\frac{4}{3}\pi r^3}$

$=\frac{2\times {10}^{30}}{\frac{4}{3}\times \pi \times 7^3\times {10}^{24}}=1392.0257kg/m^3$

The density of the Sun is in the range of density of liquids and solutions not gases.

This high density of the hot plasma arises due to inward gravitational attraction on outer layers due to inner layers of the Sun, and the gases inside the sun are subjected to enormous hydrostatic pressure of gases themselves.
