Question 1.
What is mass balance?
Show hintHide hint
Think about inputs and outputs of mass.
Question 2.
Define diffusion.
Show hintHide hint
It's how substances spread out.
3Question 3.
What is the primary process through which mass enters and exits a sediment volume?
- Convection
- Diffusion
- Evaporation
Show hintHide hint
Recall the mechanism that is mentioned to describe movement of materials.
4Question 4.
True or False: A higher retardation factor results in faster diffusion.
- True
- False
Show hintHide hint
Think about what retardation means in this context.
Question 5.
Given a sediment system with known concentration gradients, calculate the diffusion rate using Fick's laws.
Show hintHide hint
Remember to check the values for concentration change and distance.
Question 6.
Discuss how a change in porosity affects the effective diffusivity in a sediment system.
Show hintHide hint
Think about how movement is impacted by space within solids.
