| 1. | It some cases, the rate of diffusion in air is amazingly high.
|
| 2. | The rate of diffusion increases with temperature as atoms are moving faster.
|
| 3. | Do network effects drive the rate of diffusion of new drugs?
|
| 4. | In liquids, an increase in temperature increases the rate of diffusion.
|
| 5. | The rate of diffusion in solids is also increased by temperature.
|
| 6. | As a result, the flame speed is limited by the rate of diffusion.
|
| 7. | Similarly, much smaller ratios indicate a higher rate of diffusion relative to advection.
|
| 8. | Tumors are limited in size by the rate of diffusion of nutrients and waste.
|
| 9. | However, since liquids are incompressible, the rate of diffusion is not affected by the pressure.
|
| 10. | The relative rates of diffusion and dissolution are illustrated by two extreme cases in Figure 3.
