A) \[{{45}^{o}}C\]
B) \[{{90}^{o}}C\]
C) \[{{30}^{o}}C\]
D) \[{{60}^{o}}C\]
Correct Answer: D
Solution :
Temperature of interface \[T=\frac{{{K}_{1}}{{\theta }_{1}}+{{K}_{2}}{{\theta }_{2}}}{{{K}_{1}}+{{K}_{2}}}\] \[=\frac{300\times 100+200\times 0}{300+200}=60{}^\circ C\]You need to login to perform this action.
