A) \[{{40}^{o}}C\]
B) \[-{{10}^{o}}C\]
C) \[{{10}^{o}}C\]
D) \[{{20}^{o}}C\]
Correct Answer: B
Solution :
Temperature gradient \[=\frac{-dT}{dX}\] \[\frac{{{T}_{1}}-{{T}_{2}}}{dX}=80\] \[\frac{30-{{T}_{2}}}{0.5}=80\] \[\Rightarrow \] \[{{T}_{2}}=-{{10}^{o}}C\]You need to login to perform this action.
