A) \[2Q\ kW{{m}^{-2}}\]
B) \[4Q\ kW{{m}^{-2}}\]
C) \[6Q\ kW{{m}^{-2}}\]
D) \[8Q\ kW{{m}^{-2}}\]
Correct Answer: B
Solution :
\[{{E}_{2}}={{E}_{1}}\frac{T_{2}^{4}}{T_{1}^{4}}=Q\times \frac{{{(273+151)}^{4}}}{{{(273+27)}^{4}}}={{\left( \frac{424}{300} \right)}^{4}}=3.99Q\approx 4Q\]You need to login to perform this action.
