find the speed of sound (in m/s) at -35°C at 1 atm pressure in dry air

  • physics please help! - ,

    There are many websites online provide the speed of sound in air as a function of temperature.

    Try this one:

    The most accurate formula is
    Speed of sound = sqrt[(gamma)*R*T]
    where T is the Kelvin temperatuere and gamma is the specific heat ratio, which is 1.4 for dry air. R' is the molar gas constant divided by the molecular weight of air .
