Quizz 4

Immiscible liquids are those which won't mix to give a single phase.

• True

• False

Oil and water are miscible.

• True

• False

The main 2 types of mass transport processes are:

• Molecular diffusion and advection

• Advection and convection

• Molecular diffusion and radiation

Molecular diffusion occurs between 2 immiscible fluids.

• True

• False

Mass transport by diffusion is related to the ------------ between 2 miscible fluids.

Advection is the mass transport process related to the water ------.

This figure represents mass transport processes by advection-diffusion

• True

• False

This figure represents the mass transport of a contaminant in an aquifer.

• We can confirm that the contaminant and freshwater are not miscible.

• We can confirm that advection and diffusion processes occur

• We can confirm that there is pure diffusion in this case

Based on the figure, select if the contaminant is saltwater or oil.

• Saltwater

• Oil

In this figure we can see:

• The processes of mass transport by pure molecular diffusion

• The processes of mass transport by pure advection

• The process of mass transport by both advection and molecular diffusion
