Question 1.
Define evaporation.
Show hintHide hint
What happens to liquids under heat?
Question 2.
What is a mass transfer coefficient?
Show hintHide hint
It relates to how quickly substances move between phases.
3Question 3.
What is the primary driving force for evaporation?
- Temperature
- Concentration
- Air Pressure
Show hintHide hint
Think about how heat affects liquid behavior.
4Question 4.
True or False: Mass transfer coefficients are the same for all environments.
- True
- False
Show hintHide hint
Consider how lakes may differ from rivers.
Question 5.
A chemical is spilled into a lake with a known area and initial concentration. Calculate how long it will take for the concentration in the lake to drop to half of its initial value, using appropriate mass transfer coefficients.
Show hintHide hint
This is a first-order decay problem; remember to apply ln calculations.
Question 6.
Model the dispersion of a volatile chemical from a spill on a road. Consider factors like wind speed, temperature, and area for evaporation.
Show hintHide hint
Consider how these parameters interact dynamically over the time frame.
