A) \[{{(1000)}^{4}}(b)\]
B) \[{{(727)}^{2}}\]
C) \[727{{)}^{4}}\]
D) \[{{(727)}^{2}}\]
Correct Answer: A
Solution :
[a] According to Stefan's law, \[\operatorname{E}\propto {{T}^{4}}\] \[\propto {{(t+273)}^{4}}K~[727{}^\circ C=(727+273)K]\] \[\propto {{(727+273)}^{4}}K\] \[\propto {{(1000)}^{4}}K\]You need to login to perform this action.
