1.3. Examples of Mass Transfer

Try these first

1. 1.

   What is mass transfer?

   Hint

   Think about how solids dissolve in liquids.

2. 2.

   Give an example of interface mass transfer.

   Hint

   Where do you often see oil floating?

3. 3.

   What primarily drives mass transfer?

   • Temperature
   • Pressure
   • Concentration Gradient

   Hint

   Think about areas where concentrations differ.

4. 4.

   Molecular diffusion can occur without bulk motion. True or False?

   • True
   • False

   Hint

   Consider whether substances can move independently.

5. 5.

   Evaluate the long-term environmental impact of a chemical spill with a lower density than water. What remediation strategies may be required?

   Hint

   Consider factors such as evaporation and dissolution.

6. 6.

   Discuss how increased river velocity impacts the diffusion rate of a chemical spill. What additional factors might play a role?

   Hint

   Think about how swift currents might carry pollutants further downstream.
