Question

Which of the following statement given below are correct for monoatomic gas?

I. $C_{V}=\frac{3}{2} R$

II. $C_{P}=\frac{5}{2} R$

III. $C_{P}-C_{V}=2 R$

IV. $\frac{C_{P}}{C_{V}}=\frac{5}{3}$

• A. I only
• B. I, II and IV
• C. III only
• D. None

Answer 1

Answer: (B)

$C_{P}=\frac{5}{2} R $
$ C_{V}=\frac{3}{2} R $
$\therefore \frac{C_{P}}{C_{V}}=\frac{5}{3}$
