$C=9Nk_{B}({\frac {T}{\theta _{D}}})^{3}\int _{0}^{\theta _{D}/T}{\frac {x^{4}e^{x}}{(e^{x}-1)^{2}}}dx$

$\theta _{D}={\frac {h}{k_{B}}}\left({\frac {6\pi ^{2}N}{V}}\right)^{1/3}$

$C=9\cdot N\cdot k_{B}({\frac {T}{{\frac {h}{k_{B}}}\left({\frac {6\cdot \pi ^{2}\cdot N}{V}}\right)^{1/3}}})^{3}\int _{0}^{{\frac {h}{k_{B}}}\left({\frac {6\cdot \pi ^{2}\cdot N}{V}}\right)^{1/3}/T}{\frac {x^{4}\cdot e^{x}}{(e^{x}-1)^{2}}}dx$
