AP EAMCET · PHYSICS · Kinetic Theory of Gases
If the ratio of universal gas constant and specific heat capacity at constant volume of a gas is given by 0.67, then the gas is
- A monoatomic
- B diatomic
- C polyatomic
- D a mixture of diatomic and polyatomic gases
Answer & Solution
Correct Answer
(A) monoatomic
Step-by-step Solution
Detailed explanation
\( \gamma - 1 = R/C_v \) \( \gamma = 1 + 0.67 \) \( \gamma = 1.67 \) \( \text{Since } \gamma \approx 5/3 \), the gas is monoatomic.
