A) \[{{400}^{o}}C\]
B) \[{{450}^{o}}C\]
C) \[{{500}^{o}}C\]
D) \[{{550}^{o}}C\]
Correct Answer: C
Solution :
By using, \[{{R}_{t}}={{R}_{0}}(1+a\,\Delta t)\] According to the question, \[3\times {{R}_{0}}={{R}_{0}}(1+4\times {{10}^{-3}}\Delta t)\] \[\Rightarrow \] \[\Delta r={{500}^{o}}C\] final temperature \[=500+0={{500}^{o}}C\]You need to login to perform this action.
