A) 971 K
B) 1190 K
C) 2001 K
D) 1458 K
Correct Answer: B
Solution :
\[\frac{{{Q}_{2}}}{{{Q}_{1}}}={{\left( \frac{{{T}_{2}}}{{{T}_{1}}} \right)}^{4}}\Rightarrow \frac{2}{1}={{\left( \frac{{{T}_{2}}}{{{T}_{1}}} \right)}^{4}}\] \[\Rightarrow T_{2}^{4}=2\times T_{1}^{4}=2\times {{(273+727)}^{4}}\]Þ \[{{T}_{2}}=1190K\].You need to login to perform this action.
