A gaseous mixture consists of 16 g of helium and 16 g of oxygen/The ratio\[\frac{{{C}_{p}}}{{{C}_{v}}}\] of the mixture is
AIEEE Solved Paper-2005
A)1.59
B) 1.62
C) 1.4
D) 1.54
Correct Answer:
B
Solution :
For the mixture of gases For helium, and For oxygen, and For He, For Now, \[{{c}_{v}}=\frac{R}{\gamma -1}\] \[\gamma -1=\frac{R}{{{C}_{V}}}\,\gamma =\frac{R}{{{C}_{V}}}+1=\frac{R}{\frac{29}{18}R}+1\]
