Answer» estion is incomplete . A complete QUESTION is -----> How many degrees of FREEDOM do the molecules of a gas have if the density at ntp is 1.3 kg/m³ and velocity of sound is 330 m/s ?solution : use the formula, where v is velocity of sound , i is degree of freedom, P is ATMOSPHERIC pressure and is density of gas. now, or, or, or, hence, i = (2 × 10^5)/(330 × 330 × 1.3 - 10^5) ≈ 5hence, degree of freedom is 5 |
