Question 1.
Define 'flux' in the context of environmental science.
Show hintHide hint
Think about how substances move in the environment.
Question 2.
What does the gradient technique measure?
Show hintHide hint
Consider surfaces and how we can measure emissions.
3Question 3.
What does the gradient technique primarily measure?
- Velocity
- Concentration differences
- Temperature
Show hintHide hint
Focus on what the term 'gradient' suggests.
4Question 4.
Is turbulence beneficial for mass transfer?
- True
- False
Show hintHide hint
Think about how fluid flows in real-world scenarios.
Question 5.
A scientist measures water vapor concentrations at two heights, finding 2 mg/m³ at 1m and 5 mg/m³ at 4m. Using the gradient technique, calculate the expected flux if the diffusion coefficient is 0.5 m²/s.
Show hintHide hint
Ensure to apply the correct heights and concentration values.
Question 6.
Discuss the variation in flux measurements taken at different times of the day. How might temperature and wind influence your readings?
Show hintHide hint
Consider how environmental changes impact measurement conditions.
