A cylinder consists of a gas mixture of helium and oxygen. If the mass of helium is \(4 \mathrm{~g}\) and the mass of oxygen is \(32 \mathrm{~g}\), then the ratio of specific heat of the mixture \(\left(C_p / C_V\right)\)
- A 2/3
- B 3/2
- C 1/2
- D 1/3
Answer & Solution
Correct Answer
(B) 3/2
Step-by-step Solution
Detailed explanation
Mass of helium, \(m_{\mathrm{He}}=4 \mathrm{~g}\) Mass of oxygen, \(m_{\mathrm{O}}=32 \mathrm{~g}\) Helium is a monoatomic gas. \(\therefore\) Degrees of freedom, \(f_1=3\) Oxygen is a diatomic gas. \(\therefore\) Degrees of freedom, \(f_2=5\) \(4 \mathrm{~g}\) helium contains…
