A) 8
B) \[\frac{3}{2}\,R\]
C) 2R
D) \[2.5\,\,R\]
Correct Answer: C
Solution :
\[{{\left( {{C}_{V}} \right)}_{mix}}=\frac{{{\mu }_{1}}{{C}_{{{V}_{1}}}}+{{\mu }_{2}}{{C}_{V2}}}{{{\mu }_{1}}+{{\mu }_{2}}}\] \[=\,\,\frac{1\times \frac{3}{2}R+1\times \frac{5}{2}\,\,R}{1+1}=2\,R\] \[\left( {{\left( {{C}_{V}} \right)}_{mono}}=\frac{3}{2}\,\,R,\,\,{{\left( {{C}_{V}} \right)}_{di}}=\frac{5}{2}\,\,R \right)\]
