| 1. | In liquids, molecular diffusion alone is hardly efficient for mixing.
|
| 2. | In gases, molecular diffusion is dependent on pressure and temperature.
|
| 3. | It does not include transport of substances by molecular diffusion.
|
| 4. | Molecular diffusion occurs in gases, liquids, and solids.
|
| 5. | Molecular diffusion will slowly evolve the parcel properties.
|
| 6. | This pressure for molecular diffusion can be called a " death-wish ".
|
| 7. | Under normal conditions, molecular diffusion dominates only on length scales between nanometer and millimeter.
|
| 8. | The approach treats dissipation of kinetic energy at sub-grid scales as analogous to molecular diffusion.
|
| 9. | This has a significant effect on the overall hydraulic conductivities ( water permeabilities ) and molecular diffusion coefficients.
|
| 10. | However there may be instances where both Knudsen diffusion and molecular diffusion D _ { AB } are important.
