A) \[{{100}^{o}}C\]
B) \[{{125}^{o}}C\]
C) \[{{150}^{o}}C\]
D) \[{{200}^{o}}C\]
Correct Answer: A
Solution :
Temperature of interface \[\theta =\frac{{{k}_{1}}{{\theta }_{1}}{{l}_{2}}+{{k}_{2}}{{\theta }_{2}}{{l}_{1}}}{{{k}_{1}}{{l}_{2}}+{{k}_{2}}{{l}_{1}}}\] \[=\frac{2k\times 0\times l+k\times 300\times l}{kl+2kl}={{100}^{o}}C\]You need to login to perform this action.
