Question

$C_v$ values for monoatomic and diatomic gases respectively are

• A. $\frac{1}{2}R, \frac{3}{2}R$
• B. $\frac{3}{2}R, \frac{5}{2}R$
• C. $\frac{5}{2}R, \frac{7}{2}R$
• D. $\frac{3}{2}R, \frac{3}{2}R$

Answer 1

Answer: (B)

$\frac{3}{2}R, \frac{5}{2}R$

Answer 2

For monoatomic gas, $C_{v}=\frac{3}{2}R$ For diatomic gas, $C_{v}=\frac{5}{2}R$
