Three different forms of this process are quantified by a single j factor in the Chilton–Colburn analogy. This process names a theorem that links the material derivative and the integral over a control volume of a quantity. Coefficients named for this macroscopic process are related to integrals of a correlation function by the Green–Kubo relations. The matrix of coefficients named for this process is symmetric for near-equilibrium processes described by Onsager’s reciprocal relations. This process names an equation that relates the time evolution of the distribution function to force, diffusion, and collision terms. (10[1])Boltzmann’s equation is often named for this process. For 10 points, name this ubiquitous, broadly-defined thermodynamic process that may occur through conduction when (10[1])it occurs to heat. (10[7]0[1])■END■
