A) \[20\ J\]
B) \[40\ J\]
C) \[80\ J\]
D) \[160\ J\]
Correct Answer: D
Solution :
\[{{(Q)}_{Black\,body}}=A\sigma {{T}^{4}}t\] Þ \[Q\propto {{T}^{4}}\] Þ \[{{Q}_{2}}={{Q}_{1}}{{\left( \frac{{{T}_{2}}}{{{T}_{1}}} \right)}^{4}}\]\[=10\,{{\left( \frac{273+327}{273+27} \right)}^{4}}\]\[=10\,{{\left( \frac{600}{300} \right)}^{4}}=160J\]You need to login to perform this action.
