WebJan 16, 2024 · 9. My professor in kinetic gas theory said that when considering the Boltzmann Transport Equation (BCE) ∂ t f + p → m ⋅ ∇ q → f + F → ⋅ ∇ p → f = ( ∂ t f) C o l l. Over long periods of time, the system tends to relax, which makes the distribution f homogenous ( ∇ q → f = 0) and time independent ( ∂ t f = 0 ). This ... Websecond law of thermodynamics and learn what temperature is. 1 Derivation of the Boltzmann equation These notes are based on the excellent survey articles [1] and [2], which are far more comprehensive and delve into much more material. Consider a gas of N identical particles in R3, which we model temporarily as hard spheres of a small radius r.
