- A \(C_p-C_V\) is larger for a diatomic ideal gas than for a monoatomic ideal gas
- B \(C_p+C_V\) is larger for a diatomic ideal gas than for a monoatomic ideal gas.
- C \(\frac{C_p}{C_V}\) is larger for a diatomic ideal gas than for a monoatomic ideal gas
- D \(C_p \cdot C_V\) is larger for a diatomic ideal gas than for a monoatomic ideal gas
Answer & Solution
Correct Answer
(D) \(C_p \cdot C_V\) is larger for a diatomic ideal gas than for a monoatomic ideal gas
Step-by-step Solution
Detailed explanation
For monoatomic gas,
\(C_p=\frac{5}{2} R \text { and } C_V=\frac{3}{2} R\)
For diatomic gas,
\(C_p=\frac{7}{2} R \text { and } C_V=\frac{5}{2} R\)
\(C_p=\frac{5}{2} R \text { and } C_V=\frac{3}{2} R\)
For diatomic gas,
\(C_p=\frac{7}{2} R \text { and } C_V=\frac{5}{2} R\)
