Question 1.
Define interphase mass transfer in your own words.
Show hintHide hint
Think of an example like water evaporating to solidify your understanding.
Question 2.
What do we mean by the term 'resistance' in mass transfer?
Show hintHide hint
Consider barriers like temperature or pressure.
3Question 3.
What is interphase mass transfer?
- A process of energy exchange
- A process of mass exchange between phases
- Nothing important
Show hintHide hint
Think about examples like evaporation.
4Question 4.
True or False: The steady state assumption indicates that concentration at the interface is changing continuously.
- True
- False
Show hintHide hint
Consider what steady state means in terms of flows.
Question 5.
Assume you have two lakes, one with high wind speed and another with calm waters. Analyze how this difference affects the mass transfer rates of pollutants from water to air.
Show hintHide hint
Consider how the physical movement of air impacts resistive forces.
Question 6.
Design an experimental setup to measure the concentration of a pollutant at the air-water interface, justifying your choices of equipment and methodology.
Show hintHide hint
Think about technologies currently used in microanalysis.
