WebJan 29, 2024 · The molecular masses are different from gas to gas, and if all gases have the same average kinetic energy, the average speed of a gas is unique. Based on the above assumption or theory, Boltzmann (1844-1906) and Maxwell (1831-1879) extended the theory to imply that the average kinetic energy of a gas depends on its temperature. WebMaxwell-Boltzmann Distribution of Speeds. The distribution function for speeds of particles in an ideal gas at temperature T is. f ( v) = 4 π ( m 2 k B T) 3 / 2 v 2 e ( − m v 2 / ( 2 k B T)). The factors before the v 2 are a normalization constant; they make sure that N ( 0, ∞) = N by making sure that ∫ 0 ∞ f ( v) d v = 1. WebThe calculation above was done for dry air, and moisture content in the air would be expected to increase the speed of sound slightly because the molecular weight of water vapor is 18 compared to 28.95 for dry air. A revised average molecular weight could be calculated based on the vapor pressure of water in the air. shiseido malaysia outlet
