A) \[31.2{}^\circ C\]
B) \[32.8{}^\circ C\]
C) \[36.7{}^\circ C\]
D) \[38.2{}^\circ C\]
Correct Answer: D
Solution :
[d] \[{{\theta }_{mix}}=\frac{{{m}_{w}}{{\theta }_{w}}-\frac{{{m}_{i}}{{L}_{i}}}{{{c}_{w}}}}{{{m}_{i}}+{{m}_{w}}}\] \[=\frac{100\times 50-10\times \frac{80}{1}}{10+100}\] \[=38.2{}^\circ C\]
