Question

Which of the following statement given below are correct for monoatomic gas? I. CV=(3/2) R II. CP=(5/2) R III. CP-CV=2 R IV. (CP/CV)=(5/3) (A) I only (B) I, II and IV (C) III only (D) None

CP=(5/2) R CV=(3/2) R ∴ (CP/CV)=(5/3)

Q. 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. $\frac{C _{P}}{C _{V}} = \frac{5}{3}$

I only

I, II and IV

III only

None

$C_{P} = \frac{5}{2} R$
$C_{V} = \frac{3}{2} R$
$∴ \frac{C _{P}}{C _{V}} = \frac{5}{3}$
