What is Fick's Law of Diffusion?
Think about how a perfume spreads in a room.
Name one factor that increases the diffusion coefficient.
Consider the effect of heat on movement.
What does Fick's law indicate?
Consider how fragrances spread.
True or False: An increase in temperature decreases diffusion.
Think of how heating something speeds it up.
Calculate the expected flux of a pollutant in water if its concentration gradient between the sediment and water is known, considering a diffusion coefficient of 0.1 m²/s.
Remember that the negative sign indicates direction; focus on the concentration gradient.
Assess how changing the density of water from 1g/cm³ to 0.5g/cm³ would impact the diffusion rate of a pollutant.
Compare the movement of a ping pong versus a bowling ball in water.
