Kinetic Theory - Result Question 26
26. The ratio of the specific heats $\frac{C_p}{C_v}=\gamma$ in terms of degrees of freedom (n) is given by
[2015]
(a) $(1+\frac{n}{3})$
(b) $(1+\frac{2}{n})$
(c) $(1+\frac{n}{2})$
(d) $(1+\frac{1}{n})$
Show Answer
Answer:
Correct Answer: 26. (b)
Solution:
- (b) Let ’ $n$ ’ be the degree of freedom
$\gamma=\frac{C_p}{C_v}=\frac{(\frac{n}{2}+1) R}{(\frac{n}{2}) R}=(1+\frac{2}{n})$
