The ratio of molar specific heats of oxygen is
- 1.4
- 1.67
- 1.33
- 1.28
The Correct Option is A
Approach Solution - 1
The ratio of the molar specific heats of oxygen is given by the ratio \( \gamma = \frac{C_p}{C_v} \), where:
- \( C_p \) is the specific heat at constant pressure.
- \( C_v \) is the specific heat at constant volume.
For a diatomic gas like oxygen (O₂), the value of \( \gamma \) is approximately 1.4.
Thus, the correct ratio of molar specific heats for oxygen is \( \gamma = 1.4 \).
Therefore, the correct answer is (A) 1.4.
Approach Solution -2
The ratio of molar specific heats (γ) for a gas is given by: \[ \gamma = 1 + \frac{2}{f} \] where f is the number of degrees of freedom. For O₂, f = 5, so \[ \gamma = 1 + \frac{2}{5} = 1.4 \]
