There are several ways to calculate the speed of sound c, in a gas, for example Y.R.T Cs M where y is the adiabatic coefficient of the gas, R is the ideal gas constant, T is the temperature in Kelvin, and M is the molar mass. Find the speed of sound in air at T = 0°C and at T = 20° C, use y = 1.4, M = 28.97 g/mol, and 0°C = 273.15 K. The speed of sound in air at 0°C, c, = Units Select an answer The speed of sound in air at 20°C, c2 = Units Select an answer A convenient approximate way to find the speed of sound at low temperatures (note that the temperature must be small in Celsius, not in Kelvin: T(in C) « 273.15) is the following T Co/1 + = Co + a T, Cs 273.15 where T is the gas temperature in Celsius and co and a are constants. Using the values you found above (C1 and c2) find the constants co and a for the speed of sound in air. The constant co = Units Select an answer The constant a = Units Select an answer v Use the second (approximate) equation to find the speed of sound in air at 12 C.
