Physics - Heat & Thermo Question with Solution | TestHub

Solid atom possesses$6$degrees of freedom due to vibrations at high temperature.

$C_v=\frac{1}{2}fR=\frac{6R}{2}=3R$for$1 \mathrm{mole}$
$\therefore$Specific heat capacity in$\mathrm{J}\mathrm{ }{\mathrm{kg}}^{-1}\mathrm{ }{\mathrm{K}}^{-1}=\frac{C_v}{M}$

$=\frac{3R}{M}=\frac{3\times 8.314}{27}\times 1000$

$\approx 925$
