Question

Two mole of argon are mixed with one mole of hydrogen, then C_p/C_v for the mixture is nearly

• A. 1.2
• B. 1.3
• C. 1.4
• D. 1.5

Answer 1

Answer: (C)

1.4

Answer 2

Average degree of freedom

f_av = $\frac { 2 \times 3 + 1 \times 5 } { 2 + 3 } = \frac { 11 } { 5 }$

ν_mix = 1 + $\frac { 16 } { 11 }$ = 1.4

Hence, C is correct Answer.
