A) 162 J
B) 135 J
C) 40.5 J
D) 13.5 J
Correct Answer: C
Solution :
According to Stefan's law, \[E\propto {{T}^{4}}\] \[\frac{{{E}_{1}}}{{{E}_{2}}}={{\left[ \frac{{{T}_{1}}}{{{T}_{2}}} \right]}^{4}}\] \[\frac{{{E}_{1}}}{0.5}={{\left[ \frac{273+627}{273+27} \right]}^{4}}\] \[{{E}_{1}}=0.5{{\left[ \frac{900}{300} \right]}^{4}}\] \[{{E}_{1}}=40.5\,\,J\]You need to login to perform this action.
