So, if we want to calculate the speed of sound in air at we can use the following equation that relates with the temperature:
(1)
Where:
is the Heat capacity ratio for air
is the Universal Gas constant
is the air temperature in Kelvin
is the air molar mass
(2)
Finally:
This is the speed of sound at 313 K
