AP EAMCET · PHYSICS · Kinetic Theory of Gases
If the ratio of specific heats of a gas at constant pressure and at constant volume is \(\gamma\), then the number of degrees of freedom of the rigid molecules of the gas is
- A \(\frac{3 \gamma-1}{2 \gamma-1}\)
- B \(\frac{2}{\gamma-1}\)
- C \(\frac{9}{2}(\gamma-1)\)
- D \(\frac{25}{2}(\gamma-1)\)
Answer & Solution
Correct Answer
