Question

Calculate the temperature of the Sun if density is $1.4 g c m^{- 3}$ , pressure is $1.4 \times 10^{9}$ atmosphere and average molecular weight of gases in the Sun in $2 g / m o l e$ . [Given $R = 8.4 J m o l^{- 1} K^{- 1}]$ .

Solution

Calculation of the temperature $= T$
Density of the sun $= 1.4 g / c m^{3}$
Pressure $= 1.4 \times 10^{5} a t m o s p h e r e$
Average molecular weight of gases in the sun $= 2 g / m o l e$
$R = 8.4 J m o l^{- 1} K^{- 1} \frac{P V}{T} = n R \frac{1.4 \times 10^{3} \times 10^{5} \times 1.4 \times 10^{- 3}}{(10^{- 2})^{3} \times 8.4} = T T = 2.33 \times 10^{16} K$
