Question

The ratio of molar specific heats of oxygen is

• A. 1.4
• B. 1.67
• C. 1.33
• D. 1.28

Answer 1

The Correct Option is A

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.
