The speed of sound is solely dependant on temperature. M = γ R T. where γ is the ratio of specific heats, R is the molar gas constant and T … WebAt the temperature of ϑ = 0°C the speed of sound in dry air was determined to be c = 331.3 m/s. 0°C equals 68°F. It makes no sense to give the speed of sound adding the words at the "standard atmosphere at sea level". To get the speed of sound the temperature is important, not the barometric pressure. sulfate free shampoos and conditioners
