A) \[200{}^\circ C\]
B) 200 K
C) \[800{}^\circ C\]
D) 800 K
Correct Answer: D
Solution :
In first state, \[E=\sigma {{(673)}^{4}}\] In second state, \[2E=\sigma {{T}^{4}}\] \[\therefore \] \[\frac{1}{2}={{\left( \frac{673}{T} \right)}^{4}}\] \[T={{(2)}^{1/4}}\times 673=800\,K\]You need to login to perform this action.
