Consider an ideal gas with a molar mass (mass per mole) of Mair = 0.0289 kg/mol, the velocity of sound in the adiabatic condition can be described as c = (/1 + 273.15K where 0 = T - 273.1K. Briefly derive the equation and find ( ). Hint: C = KBTY m or C= \ RTY RTY A,m M air A. = 6.022×1033, R= 8.314 J/(mol-K), y =
