A) 800 J
B) 373 J
C) 273 J
D) None of these
Correct Answer: C
Solution :
\[dQ=nCdT\] \[dQ=nk\frac{{{T}^{3}}}{{{\theta }^{3}}}dT\] \[Q=\frac{nk}{{{\theta }^{3}}}\int_{{{T}_{1}}}^{{{T}_{2}}}{{{T}^{3}}dT}\] \[=\frac{nK}{{{\theta }^{3}}}\left( \frac{T_{2}^{4}-T_{1}^{4}}{4} \right)\] \[=\frac{2\times 1940\times ({{50}^{4}}-{{10}^{4}})}{{{(281)}^{3}}\times 4}\] \[=272.79\,\,J=273\,\,J\]You need to login to perform this action.
