Calculating average molecular speed
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.
