At what frequency would the wavelength of sound in air be equal to the mean free path of oxygen molecules at 1.3 atm pressure and -2.0°C? Take the diameter of an oxygen molecule to be 5.7 × 10-8 cm and the speed of sound to be 320 m/s.
At what frequency would the wavelength of sound in air be equal to the mean free path of oxygen molecules at 1.3 atm pressure and -0.75°C? Take the diameter of an oxygen molecule to be 4.8 x 10-8 cm and the speed of sound to be 350 m/s.
some context Problem 3: Use simple kinetic theory of gases discussed in section 1.3.2 as well as Fourer's law of condustion to prove: 2 R373 D11 = 3113/202pm Dal We were unable to transcribe this imageof a nes. the xed the led negligible The following assumptions about the structure of the cases are made in order to investigate the statistical rules of the random motion of the molecules: The size of the gas molecules is negligible compared with the distance...
