Problem 2.66

How many degrees of freedom have the gas molecules, if under standard conditions the gas density is \(\rho=1.3 \mathrm{mg} / \mathrm{cm}^{3}\) and the velocity of sound propagation in it is \(v=330 \mathrm{~m} / \mathrm{s}\).

Reveal Answer
i=2/(ρv2/p1)=5i=2 /\left(\rho v^{2} / p-1\right)=5
