A) \[20{}^\circ C\]
B) \[40{}^\circ C\]
C) \[80{}^\circ C\]
D) \[100{}^\circ C\]
Correct Answer: B
Solution :
The rate of heat flow, \[\frac{Q}{t}=\frac{KA\Delta \theta }{l}\] \[\Rightarrow \] \[6000=\frac{200\times 0.75\times \Delta \theta }{1}\] \[\Delta \theta =\frac{6000\times 1}{200\times 0.75}=40\,{{\,}^{o}}C\]You need to login to perform this action.
