A função de distribuição de velocidades de moléculas de um gás em um plano é: f(v) = m/(kT) v exp[-mv2/(2kT)]
a) Conceitue velocidade mais provável e encontre uma fórmula para ela.
b) Deduza a equação da velocidade média.
c) Encontre a função de distribuição de energia.
Dado: ∫ u^2n exp(-au^2) du = [1 x 3 x 5 x.. (2n - 1) x ( pi/a)^1/2] / [2^n + 1 x a^n]
