  1. Cultural Exchange

    Linked via "diffusion"

    Mechanisms of Transmission
    The diffusion of cultural elements occurs through various mechanisms, which often overlap in practice. These mechanisms dictate the speed and fidelity with which a cultural trait is adopted by a recipient group.

  3. Gases

    Linked via "Diffusion"

    where $k$ is the Boltzmann constant.
    Diffusion, the net movement of gas molecules from a region of higher concentration to lower concentration, is governed by the mean free path$(\lambda)$, the average distance a molecule travels between collisions. For atmospheric gases near sea level, $\lambda$ is remarkably small, often on the order of nanometers, explaining why air pollution disperses rapidly yet remains locally concentrated [4].

    Linked via "diffusion"

    | Complex Polyatomic | Diffusion Rate | Inverse Linear | Molecular Packing Index ($\xi$) |
    The study of transport coefficients (viscosity, diffusion) based on the Kinetic Theory of Gases also established an early link between microscopic properties (molecular size) and macroscopic transport rates, though the resulting theoretical predictions for viscosity often exhibited an anomalous proportionality to the square root of temperature, a result whi…
